# DB instance classes
<a name="Concepts.DBInstanceClass"></a>

The DB instance class determines the computation and memory capacity of an Amazon RDS DB instance. The DB instance class that you need depends on your processing power and memory requirements.

A DB instance class consists of both the DB instance class type and the size. For example, db.r6g is a memory-optimized DB instance class type powered by AWS Graviton2 processors. Within the db.r6g instance class type, db.r6g.2xlarge is a DB instance class. The size of this class is 2xlarge.

For more information about instance class pricing, see [Amazon RDS pricing](https://aws.amazon.com/rds/pricing/).

These classes have names of the form db.r5.*instance\$1size*.tpc*threads\$1per\$1core*.mem*ratio*. For the vCPU count and memory allocation for each optimized class, see [Supported RDS for Oracle DB instance classes](Oracle.Concepts.InstanceClasses.md#Oracle.Concepts.InstanceClasses.Supported).

**RDS Custom**  
For information about the DB instance classes supported in RDS Custom, see [DB instance class support for RDS Custom for Oracle](custom-oracle-feature-support.md#custom-reqs-limits.instances) and [DB instance class support for RDS Custom for SQL Server](custom-reqs-limits.instancesMS.md).

In the following table, you can find details about supported Amazon RDS DB instance classes for each Amazon RDS DB engine. The cell for each engine contains one of the following values:

Yes  
The instance class is supported for all versions of the DB engine.

No  
The instance class isn't supported for the DB engine.

*specific-versions*  
The instance class is supported only for the specified database versions of the DB engine.

Amazon RDS periodically deprecates major and minor DB engine versions. Not all AWS Regions might have support for earlier engine versions. For information about current supported versions, see topics for the individual DB engines: [Db2 versions](Db2.Concepts.VersionMgmt.Supported.md), [MariaDB versions](MariaDB.Concepts.VersionMgmt.md#MariaDB.Concepts.VersionMgmt.Supported), [Microsoft SQL Server versions](SQLServer.Concepts.General.VersionSupport.md), [MySQL versions](MySQL.Concepts.VersionMgmt.md), [Oracle versions](Oracle.Concepts.database-versions.md), and [PostgreSQL versions](PostgreSQL.Concepts.General.DBVersions.md).

# Determining DB instance class support in AWS Regions
<a name="Concepts.DBInstanceClass.RegionSupport"></a>

To determine the DB instance classes supported by each DB engine in a specific AWS Region, you can take one of several approaches. You can use the AWS Management Console, the [Amazon RDS Pricing](https://aws.amazon.com/rds/pricing/) page, or the [describe-orderable-db-instance-options](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-orderable-db-instance-options.html) command for the AWS Command Line Interface (AWS CLI).

**Note**  
When you perform operations with the AWS Management Console, it automatically shows the supported DB instance classes for a specific DB engine, DB engine version, and AWS Region. Examples of the operations that you can perform include creating and modifying a DB instance.

## Using the Amazon RDS pricing page to determine DB instance class support in AWS Regions
<a name="Concepts.DBInstanceClass.RegionSupport.PricingPage"></a>

You can use the [Amazon RDS Pricing](https://aws.amazon.com/rds/pricing/) page to determine the DB instance classes supported by each DB engine in a specific AWS Region. 

**To use the pricing page to determine the DB instance classes supported by each engine in a Region**

1. Go to [Amazon RDS Pricing](https://aws.amazon.com/rds/pricing/).

1. In the **AWS Pricing Calculator for Amazon RDS** section, choose **Create your custom estimate now**.

1. In **Choose a Region**, choose an AWS Region.

1. In **Find a Service**, enter **Amazon RDS**.

1. Choose **Configure** for your configuration option and DB engine.

1. Use the section for compatible instances to view the supported DB instance classes.

1. (Optional) Choose other options in the calculator, and then choose **Save and view summary** or **Save and add service**.

## Using the AWS CLI to determine DB instance class support in AWS Regions
<a name="Concepts.DBInstanceClass.RegionSupport.CLI"></a>

You can use the AWS CLI to determine which DB instance classes are supported for specific DB engines and DB engine versions in an AWS Region. The following table shows the valid DB engine values.


****

| --- | --- | --- | 
|  Db2  |  `db2-ae` `db2-se`  |  [Db2 on Amazon RDS versions](Db2.Concepts.VersionMgmt.md)  | 
|  MariaDB  |  `mariadb`  |  [MariaDB on Amazon RDS versions](MariaDB.Concepts.VersionMgmt.md)  | 
|  Microsoft SQL Server  |  `sqlserver-ee` `sqlserver-se` `sqlserver-ex` `sqlserver-web`  |  [Microsoft SQL Server versions on Amazon RDS](SQLServer.Concepts.General.VersionSupport.md)  | 
|  MySQL  |  `mysql`  |  [MySQL on Amazon RDS versions](MySQL.Concepts.VersionMgmt.md)  | 
|  Oracle  |  `oracle-ee` `oracle-se2`  |  [https://docs.aws.amazon.com/AmazonRDS/latest/OracleReleaseNotes/Welcome.html](https://docs.aws.amazon.com/AmazonRDS/latest/OracleReleaseNotes/Welcome.html)  | 
|  PostgreSQL  |  `postgres`  |  [Available PostgreSQL database versions](PostgreSQL.Concepts.General.DBVersions.md)  | 

For information about AWS Region names, see [AWS RegionsAvailability Zones](Concepts.RegionsAndAvailabilityZones.md#Concepts.RegionsAndAvailabilityZones.Regions).

The following examples demonstrate how to determine DB instance class support in an AWS Region using the [describe-orderable-db-instance-options](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-orderable-db-instance-options.html) AWS CLI command.

**Note**  
To limit the output, the following examples show results only for the General Purpose SSD (`gp2`) storage type. If necessary, you can change the storage type to General Purpose SSD (`gp3`), Provisioned IOPS (`io1`), Provisioned IOPS Block Express (`io2`), or magnetic (`standard`) in the commands.

### Listing the DB instance classes that are supported by a specific DB engine version in an AWS Region
<a name="Concepts.DBInstanceClass.RegionSupport.CLI.Example1"></a>

To list the DB instance classes that are supported by a specific DB engine version in an AWS Region, run the following command.

For Linux, macOS, or Unix:

```
aws rds describe-orderable-db-instance-options --engine engine --engine-version version \
    --query "*[].{DBInstanceClass:DBInstanceClass,StorageType:StorageType}|[?StorageType=='gp2']|[].{DBInstanceClass:DBInstanceClass}" \
    --output text \
    --region region
```

For Windows:

```
aws rds describe-orderable-db-instance-options --engine engine --engine-version version ^
    --query "*[].{DBInstanceClass:DBInstanceClass,StorageType:StorageType}|[?StorageType=='gp2']|[].{DBInstanceClass:DBInstanceClass}" ^
    --output text ^
    --region region
```

For example, the following command lists the supported DB instance classes for version 13.6 of the RDS for PostgreSQL DB engine in US East (N. Virginia).

For Linux, macOS, or Unix:

```
aws rds describe-orderable-db-instance-options --engine postgres --engine-version 15.4 \
    --query "*[].{DBInstanceClass:DBInstanceClass,StorageType:StorageType}|[?StorageType=='gp2']|[].{DBInstanceClass:DBInstanceClass}" \
    --output text \
    --region us-east-1
```

For Windows:

```
aws rds describe-orderable-db-instance-options --engine postgres --engine-version 15.4 ^
    --query "*[].{DBInstanceClass:DBInstanceClass,StorageType:StorageType}|[?StorageType=='gp2']|[].{DBInstanceClass:DBInstanceClass}" ^
    --output text ^
    --region us-east-1
```

### Listing the DB engine versions that support a specific DB instance class in an AWS Region
<a name="Concepts.DBInstanceClass.RegionSupport.CLI.Example2"></a>

To list the DB engine versions that support a specific DB instance class in an AWS Region, run the following command.

For Linux, macOS, or Unix:

```
aws rds describe-orderable-db-instance-options --engine engine --db-instance-class DB_instance_class \
    --query "*[].{EngineVersion:EngineVersion,StorageType:StorageType}|[?StorageType=='gp2']|[].{EngineVersion:EngineVersion}" \
    --output text \
    --region region
```

For Windows:

```
aws rds describe-orderable-db-instance-options --engine engine --db-instance-class DB_instance_class ^
    --query "*[].{EngineVersion:EngineVersion,StorageType:StorageType}|[?StorageType=='gp2']|[].{EngineVersion:EngineVersion}" ^
    --output text ^
    --region region
```

For example, the following command lists the DB engine versions of the RDS for PostgreSQL DB engine that support the db.r5.large DB instance class in US East (N. Virginia).

For Linux, macOS, or Unix:

```
aws rds describe-orderable-db-instance-options --engine postgres --db-instance-class db.m7g.large \
    --query "*[].{EngineVersion:EngineVersion,StorageType:StorageType}|[?StorageType=='gp2']|[].{EngineVersion:EngineVersion}" \
    --output text \
    --region us-east-1
```

For Windows:

```
aws rds describe-orderable-db-instance-options --engine postgres --db-instance-class db.m7g.large ^
    --query "*[].{EngineVersion:EngineVersion,StorageType:StorageType}|[?StorageType=='gp2']|[].{EngineVersion:EngineVersion}" ^
    --output text ^
    --region us-east-1
```

### Listing AWS Regions that support a specific DB engine and instance class
<a name="Concepts.DBInstanceClass.RegionSupport.CLI.Example3"></a>

The following bash script lists all the AWS Regions that support the specified combination of DB engine and instance class.

```
#!/usr/bin/env bash
# Usage: check_region_support.sh <db-engine> <db-instance-class>

if [ $# -ne 2 ]; then
  echo "Usage: $0 <db-engine> <db-instance-class>"
  exit 1
fi
ENGINE="$1"
INSTANCE_CLASS="$2"
REGIONS=$(aws ec2 describe-regions --query "Regions[].RegionName" --output text)
for region in $REGIONS; do
  supported_count=$(aws rds describe-orderable-db-instance-options \
    --region "$region" \
    --engine "$ENGINE" \
    --db-instance-class "$INSTANCE_CLASS" \
    --query 'length(OrderableDBInstanceOptions)' \
    --output text 2>/dev/null || echo "0")
  if [ "$supported_count" -gt 0 ]; then
    echo "$region supports $INSTANCE_CLASS for $ENGINE."
  else
    echo "$region doesn't support $INSTANCE_CLASS for $ENGINE."
  fi
done
```

The following sample output checks Region support for RDS for MySQL using the db.r8g.large instance class.

```
./check_region_support.sh mysql db.r8g.large
ap-south-1 doesn't support db.r8g.large for mysql.
eu-north-1 doesn't support db.r8g.large for mysql.
eu-west-3 doesn't support db.r8g.large for mysql.
eu-west-2 doesn't support db.r8g.large for mysql.

## Changing your DB instance class
<a name="Concepts.DBInstanceClass.Changing"></a>

You can change the CPU and memory available to a DB instance by changing its DB instance class. To change the DB instance class, modify your DB instance by following the instructions in [Modifying an Amazon RDS DB instance](Overview.DBInstance.Modifying.md). 

# Configuring the processor for a DB instance class in RDS for Oracle
<a name="USER_ConfigureProcessor"></a>

Amazon RDS DB instance classes support Intel Hyper-Threading Technology, which enables multiple threads to run concurrently on a single Intel Xeon CPU core. Each thread is represented as a virtual CPU (vCPU) on the DB instance. A DB instance has a default number of CPU cores, which varies according to DB instance class. For example, a db.m4.xlarge DB instance class has two CPU cores and two threads per core by default—four vCPUs in total.

**Note**  
Each vCPU is a hyperthread of an Intel Xeon CPU core.

## Overview of processor configuration for RDS for Oracle
<a name="USER_ConfigureProcessor.Overview"></a>

When you use RDS for Oracle, you can usually find a DB instance class that has a combination of memory and number of vCPUs to suit your workloads. However, you can also specify the following processor features to optimize your RDS for Oracle DB instance for specific workloads or business needs:
+ **Number of CPU cores** – You can customize the number of CPU cores for the DB instance. You might do this to potentially optimize the licensing costs of your software with a DB instance that has sufficient amounts of RAM for memory-intensive workloads but fewer CPU cores.
+ **Threads per core** – You can disable Intel Hyper-Threading Technology by specifying a single thread per CPU core. You might do this for certain workloads, such as high-performance computing (HPC) workloads.

You can control the number of CPU cores and threads for each core separately. You can set one or both in a request. After a setting is associated with a DB instance, the setting persists until you change it.

The processor settings for a DB instance are associated with snapshots of the DB instance. When a snapshot is restored, its restored DB instance uses the processor feature settings used when the snapshot was taken.

If you modify the DB instance class for a DB instance with nondefault processor settings, either specify default processor settings or explicitly specify processor settings at modification. This requirement ensures that you are aware of the third-party licensing costs that might be incurred when you modify the DB instance.

There is no additional or reduced charge for specifying processor features on an RDS for Oracle DB instance. You're charged the same as for DB instances that are launched with default CPU configurations.

## DB instance classes that support processor configuration
<a name="USER_ConfigureProcessor.CPUOptionsDBInstanceClass"></a>

You can configure the number of CPU cores and threads per core only when the following conditions are met:

+ Your DB instance is using the Bring Your Own License (BYOL) licensing option of RDS for Oracle. For more information about Oracle licensing options, see [RDS for Oracle licensing options](Oracle.Concepts.Licensing.md).
+ Your DB instance doesn't belong to one of the db.r5 or db.r5b instance classes that have predefined processor configurations. These instance classes have names in the form db.r5.*instance\$1size*.tpc*threads\$1per\$1core*.mem*ratio* or db.r5b.*instance\$1size*.tpc*threads\$1per\$1core*.mem*ratio*. For example, db.r5b.xlarge.tpc2.mem4x is preconfigured with 2 threads per core (tpc2) and 4x as much memory as the standard db.r5b.xlarge instance class. You can't configure the processor features of these optimized instance classes. For more information, see [Supported RDS for Oracle DB instance classes](Oracle.Concepts.InstanceClasses.md#Oracle.Concepts.InstanceClasses.Supported).

You can use the following AWS CLI command to show the default vCPUs, cores, threads per core, and valid numbers of cores for an instance class. Replace `r7i.48xlarge` in the sample command with the name of your instance class.

```
aws ec2 describe-instance-types \
    --instance-types r7i.48xlarge \
    --query '{
        DefaultVCPUs: InstanceTypes[0].VCpuInfo.DefaultVCpus,
        DefaultCores: InstanceTypes[0].VCpuInfo.DefaultCores,
        DefaultThreadsPerCore: InstanceTypes[0].VCpuInfo.DefaultThreadsPerCore,
        ValidCores: InstanceTypes[0].VCpuInfo.ValidCores
    }' \
    --output json
```

In the following table, you can find the DB instance classes that support setting a number of CPU cores and CPU threads per core. You can also find the default value and the valid values for the number of CPU cores and CPU threads per core for each DB instance class.

## Setting the CPU cores and threads per CPU core for a DB instance class
<a name="USER_ConfigureProcessor.SettingCPUOptions"></a>

You can configure the number of CPU cores and threads per core for the DB instance class when you perform the following operations:
+ [Creating an Amazon RDS DB instance](USER_CreateDBInstance.md)
+ [Modifying an Amazon RDS DB instance](Overview.DBInstance.Modifying.md)
+ [Restoring to a DB instance](USER_RestoreFromSnapshot.md)
+ [Restoring a DB instance to a specified time for Amazon RDS](USER_PIT.md)

**Note**  
When you modify a DB instance to configure the number of CPU cores or threads per core, there is a brief DB instance outage.

You can set the CPU cores and the threads per CPU core for a DB instance class using the AWS Management Console, the AWS CLI, or the RDS API.

### Console
<a name="USER_ConfigureProcessor.Console"></a>

When you are creating, modifying, or restoring a DB instance, you set the DB instance class in the AWS Management Console. The **Instance specifications** section shows options for the processor. The following image shows the processor features options.

![\[Configure processor options\]](http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/images/vcpu-config.png)


Set the following options to the appropriate values for your DB instance class under **Processor features**:
+ **Core count – **Set the number of CPU cores using this option. The value must be equal to or less than the maximum number of CPU cores for the DB instance class.
+ **Threads per core** – Specify **2** to enable multiple threads per core, or specify **1** to disable multiple threads per core.

When you modify or restore a DB instance, you can also set the CPU cores and the threads per CPU core to the defaults for the instance class.

When you view the details for a DB instance in the console, you can view the processor information for its DB instance class on the **Configuration** tab. The following image shows a DB instance class with one CPU core and multiple threads per core enabled.

![\[View processor options\]](http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/images/vcpu-view.png)


For Oracle DB instances, the processor information only appears for Bring Your Own License (BYOL) DB instances.

### AWS CLI
<a name="USER_ConfigureProcessor.CLI"></a>

You can set the processor features for a DB instance when you run one of the following AWS CLI commands:
+ [create-db-instance](https://docs.aws.amazon.com/cli/latest/reference/rds/create-db-instance.html)
+ [modify-db-instance](https://docs.aws.amazon.com/cli/latest/reference/rds/modify-db-instance.html)
+ [restore-db-instance-from-db-snapshot](https://docs.aws.amazon.com/cli/latest/reference/rds/restore-db-instance-from-db-snapshot.html)
+ [restore-db-instance-from-s3](https://docs.aws.amazon.com/cli/latest/reference/rds/restore-db-instance-from-s3.html)
+ [restore-db-instance-to-point-in-time](https://docs.aws.amazon.com/cli/latest/reference/rds/restore-db-instance-to-point-in-time.html)

To configure the processor of a DB instance class for a DB instance by using the AWS CLI, include the `--processor-features` option in the command. Specify the number of CPU cores with the `coreCount` feature name, and specify whether multiple threads per core are enabled with the `threadsPerCore` feature name. 

The option has the following syntax.

```
--processor-features "Name=coreCount,Value=<value>" "Name=threadsPerCore,Value=<value>"
```

The following are examples that configure the processor:

#### Setting the number of CPU cores for a DB instance
<a name="USER_ConfigureProcessor.CLI.Example1"></a>

**Example**  
The following example modifies `mydbinstance` by setting the number of CPU cores to 4. The changes are applied immediately by using `--apply-immediately`. If you want to apply the changes during the next scheduled maintenance window, omit the `--apply-immediately` option.   
For Linux, macOS, or Unix:  

```
aws rds modify-db-instance \
    --db-instance-identifier mydbinstance \
    --processor-features "Name=coreCount,Value=4" \
    --apply-immediately
```
For Windows:  

```
aws rds modify-db-instance ^
    --db-instance-identifier mydbinstance ^
    --processor-features "Name=coreCount,Value=4" ^
    --apply-immediately
```

#### Setting the number of CPU cores and disabling multiple threads for a DB instance
<a name="USER_ConfigureProcessor.CLI.Example2"></a>

**Example**  
The following example modifies `mydbinstance` by setting the number of CPU cores to `4` and disabling multiple threads per core. The changes are applied immediately by using `--apply-immediately`. If you want to apply the changes during the next scheduled maintenance window, omit the `--apply-immediately` option.  
For Linux, macOS, or Unix:  

```
aws rds modify-db-instance \
    --db-instance-identifier mydbinstance \
    --processor-features "Name=coreCount,Value=4" "Name=threadsPerCore,Value=1" \

```

#### Viewing the valid processor values for a DB instance class
<a name="USER_ConfigureProcessor.CLI.Example3"></a>

**Example**  
You can view the valid processor values for a particular DB instance class by running the [describe-orderable-db-instance-options](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-orderable-db-instance-options.html) command and specifying the instance class for the `--db-instance-class` option. For example, the output for the following command shows the processor options for the db.r3.large instance class.  

```
aws rds describe-orderable-db-instance-options --engine oracle-ee --db-instance-class db.r3.large
```

+ [DescribeDBSnapshots](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_DescribeDBSnapshots.html) – Shows the processor information for the specified DB snapshot.
+ [DescribeValidDBInstanceModifications](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_DescribeValidDBInstanceModifications.html) – Shows the valid modifications to the processor for the specified DB instance.

In the output of the preceding operations, the values for the processor features are not null only if the following conditions are met:
+ You are using an RDS for Oracle DB instance.
+ Your RDS for Oracle DB instance supports changing processor values.
+ The current CPU core and thread settings are set to nondefault values.

If the preceding conditions aren't met, you can get the instance type using [DescribeDBInstances](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_DescribeDBInstances.html). You can get the processor information for this instance type by running the EC2 operation [DescribeInstanceTypes](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstanceTypes.html).

# Hardware specifications for DB instance classes
<a name="Concepts.DBInstanceClass.Summary"></a>

In the tables in this section, you can find hardware details about the Amazon RDS DB instance classes. 

For information about Amazon RDS DB engine support for each DB instance class, see [Supported DB engines for DB instance classes](Concepts.DBInstanceClass.Support.md).

**Note**  
RDS for SQL Server supports Optimize CPU starting with 7th generation instance classes (such as db.m7i and db.r7i). The vCPU counts documented below may differ for these instance classes. For accurate vCPU counts, refer to [DB instance classes that support Optimize CPUDB instance class support](SQLServer.Concepts.General.OptimizeCPU.Support.md).

## Hardware terminology for DB instance classes
<a name="Concepts.DBInstanceClass.hardware-terminology"></a>

The following terminology is used to describe hardware specifications for DB instance classes:

**vCPU**  
The number of virtual central processing units (CPUs). A *virtual CPU *is a unit of capacity that you can use to compare DB instance classes. Instead of purchasing or leasing a particular processor to use for several months or years, you are renting capacity by the hour. Our goal is to make a consistent and specific amount of CPU capacity available, within the limits of the actual underlying hardware.

**ECU**  
The relative measure of the integer processing power of an Amazon EC2 instance. To make it easy for developers to compare CPU capacity between different instance classes, we have defined an Amazon EC2 Compute Unit. The amount of CPU that is allocated to a particular instance is expressed in terms of these EC2 Compute Units. One ECU currently provides CPU capacity equivalent to a 1.0–1.2 GHz 2007 Opteron or 2007 Xeon processor.

**Memory (GiB)**  
The RAM, in gibibytes, allocated to the DB instance. There is often a consistent ratio between memory and vCPU. As an example, take the db.r4 instance class, which has a memory to vCPU ratio similar to the db.r5 instance class. However, for most use cases the db.r5 instance class provides better, more consistent performance than the db.r4 instance class. 

**EBS-optimized**  
The DB instance uses an optimized configuration stack and provides additional, dedicated capacity for I/O. This optimization provides the best performance by minimizing contention between I/O and other traffic from your instance. For more information about Amazon EBS–optimized instances, see [Amazon EBS–Optimized instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSOptimized.html) in the *Amazon EC2 User Guide.*   
EBS-optimized instances have a baseline and maximum IOPS rate. The maximum IOPS rate is enforced at the DB instance level. A set of EBS volumes that combine to have an IOPS rate that is higher than the maximum can't exceed the instance-level threshold. For example, if the maximum IOPS for a particular DB instance class is 40,000, and you attach four 64,000 IOPS EBS volumes, the maximum IOPS is 40,000 rather than 256,000. For the IOPS maximum specific to each EC2 instance type, see [Supported instance types](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-optimized.html#ebs-optimization-support) in the *Amazon EC2 User Guide for Linux Instances*.

**Max. EBS bandwidth (Mbps)**  
The maximum EBS bandwidth in megabits per second. Divide by 8 to get the expected throughput in megabytes per second.   
General Purpose SSD (gp2) volumes for Amazon RDS DB instances have a throughput limit of 250 MiB/s in most cases. However, the throughput limit can vary depending on volume size. For more information, see [Amazon EBS volume types](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html) in the *Amazon EC2 User Guide.*

**Network bandwidth**  
The network speed relative to other DB instance classes.

## Hardware specifications for the general-purpose instance classes
<a name="hardware-specifications.gen-purpose-inst-classes"></a>

The following tables show the compute, memory, storage, and bandwidth specifications for the general-purpose instance classes.
