# Amazon EBS 最佳化的執行個體類型
Amazon EBS 最佳化執行個體使用最佳化的組態堆疊，並為 Amazon EBS I/O 提供額外的專用頻寬。此最佳化透過盡可能減少 Amazon EBS I/O 與執行個體的其他流量之間的爭用情況，為您的 EBS 磁碟區提供最佳效能。
當連接至 EBS 最佳化執行個體時，一般用途 SSD (`gp2` 和 `gp3`) 磁碟區設計為能在給定年份 99% 的時間裡提供至少 90% 的佈建 IOPS 效能，佈建 IOPS SSD (`io1` 和 `io2`) 磁碟區則設計為能在給定年份 99.9% 的時間裡提供至少 90% 的佈建 IOPS 效能。輸送量最佳化 HDD (`st1`)和冷 HDD (`sc1`) 在給定年份 99% 的時間裡提供至少 90% 的預期輸送量效能。不相容的期間約為統一分佈，目標為每小時 99% 的預期總輸送量。如需詳細資訊，請參閱「Amazon EBS 使用者指南」**中的 [Amazon EBS 磁碟區類型](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-volume-types.html)。
某些執行個體類型**預設為 EBS 最佳化**，無需啟用，且嘗試停用時也不會產生任何影響。其他執行個體類型可選擇**支援 EBS 最佳化**，您可以在啟動期間或之後啟用，需支付[額外小時費用](https://aws.amazon.com/ec2/previous-generation/#EBS-optimized_instances)。部分執行個體規格不支援 EBS 最佳化。
如需詳細的執行個體類型規格與功能，請參閱《[Amazon EC2 執行個體類型指南》](https://docs.aws.amazon.com/ec2/latest/instancetypes/instance-types.html)。
**考量事項**
+ 執行個體的 EBS 效能受限於執行個體類型效能上限，或其連接磁碟區的彙總效能 (以較小者為準)。若要達到最大 EBS 效能，執行個體必須具有連接磁碟區，這些磁碟區提供的組合效能必須等於或大於最大執行個體效能。例如，`r6i.16xlarge` 若要達到 `80,000` IOPS，每個執行個體至少須佈建 `5` `gp2` 個 `16,000` IOPS 的磁碟區 (`5` 個磁碟區 x `16,000` IOPS = `80,000` IOPS)，或者也可配置 `1` `gp3` 個磁碟區並提供 `80,000` IOPS。我們建議您選擇提供的專屬 Amazon EBS 輸送量高於應用程式所需的執行個體類型；否則，Amazon EBS 和 Amazon EC2 之間的連線將成為效能瓶頸。
+ 可連接到執行個體的 Amazon EBS 磁碟區數目上限，取決於執行個體類型和執行個體大小。如需詳細資訊，請參閱[Amazon EC2 執行個體的 Amazon EBS 磁碟區限制](volume_limits.md)。
+ IOPS 上限和輸送量限制相互依存。根據 I/O 大小，您可能會在達到另一個限制之前先達到其中一個，進而影響整體效能。若要達到最佳效果，規劃工作負載時請同時考量這兩項限制。
## 預設為 EBS 最佳化
下列執行個體類型預設為 EBS 最佳化。不需要啟用 EBS 最佳化，且停用 EBS 最佳化不具任何效果。

### 一般用途
**注意**
M8a, M8g, M8gd, M8i, M8id, M8i-flex 執行個體類型支援可設定的頻寬加權。透過這些執行個體類型，您可針對聯網效能或 Amazon EBS 效能最佳化執行個體的頻寬。下列表格列出這些執行個體類型的預設 Amazon EBS 頻寬效能。如需詳細資訊，請參閱[EC2 執行個體頻寬加權組態](configure-bandwidth-weighting.md)。

1 這些執行個體至少每 24 小時一次維持最佳效能 30 分鐘，然後就會回復至其基準效能。
2 這些執行個體可以無限期維持其上述效能。如果您的工作負載需要維持超過 30 分鐘的最佳效能，請選取其中一個執行個體。
### 記憶體最佳化
**注意**
R8a, R8g, R8gd, R8i, R8id, R8i-flex, X8g, X8aedz, X8i 執行個體類型支援可設定的頻寬加權。透過這些執行個體類型，您可針對聯網效能或 Amazon EBS 效能最佳化執行個體的頻寬。下列表格列出這些執行個體類型的預設 Amazon EBS 頻寬效能。如需詳細資訊，請參閱[EC2 執行個體頻寬加權組態](configure-bandwidth-weighting.md)。
要發揮 U7i 執行個體的最大 IOPS 效能，建議您使用 io2 BlockExpress 磁碟區。

## 支援 EBS 最佳化
以下執行個體類型支援 EBS 最佳化，但預設不啟用 EBS 最佳化。您必須在啟動期間或之後啟用 EBS 最佳化 (需支付[額外小時費用](https://aws.amazon.com/ec2/previous-generation/#EBS-optimized_instances))，以達到所述的 EBS 效能水準。

**注意**
`i2.8xlarge`、`c3.8xlarge` 和 `r3.8xlarge` 執行個體不具備專屬 EBS 頻寬，因此不提供 EBS 最佳化。在這些執行個體上，網路流量和 Amazon EBS 流量將共用同一個 10 GB 網路介面。
# 獲得最大的 Amazon EBS 最佳化效能
執行個體的 EBS 效能受限於執行個體類型效能上限，或其連接磁碟區的彙總效能 (以較小者為準)。若要達到最大 EBS 效能，執行個體必須具有連接磁碟區，這些磁碟區提供的組合效能必須等於或大於最大執行個體效能。例如，`r6i.16xlarge` 若要達到 `80,000` IOPS，每個執行個體至少須佈建 `5` `gp2` 個 `16,000` IOPS 的磁碟區 (`5` 個磁碟區 x `16,000` IOPS = `80,000` IOPS)，或者也可配置 `1` `gp3` 個磁碟區並提供 `80,000` IOPS。我們建議您選擇提供的專屬 Amazon EBS 輸送量高於應用程式所需的執行個體類型；否則，Amazon EBS 和 Amazon EC2 之間的連線將成為效能瓶頸。
**重要**
使用可設定的頻寬加權時，您執行個體的 EBS 頻寬限制可能會變更。對於具有增加聯網頻寬的 `VPC-1` 加權組態的執行個體，由於在達到 IOPS 限制前先觸及 EBS 頻寬限制，您可能會遇到 EBS 磁碟區的 IOPS 低於預期的情況。這在較大的 I/O 大小中尤其明顯。請務必測試您的特定工作負載，確保在使用選定的頻寬加權時符合效能需求。如需詳細資訊，請參閱[EC2 執行個體頻寬加權組態](configure-bandwidth-weighting.md)。
您可以使用 `EBSIOBalance%` 和 `EBSByteBalance%` 指標來協助您判斷執行個體的大小是否正確。您可以在 CloudWatch 主控台檢視這些指標，並依據您指定的閾值設定會觸發的警示。這些指標以百分比表示。維持低平衡百分比的執行個體視為有待擴展規模。平衡百分比從未低於 100% 的執行個體視為有待縮減規模。如需詳細資訊，請參閱 [使用 CloudWatch 監控您的執行個體](using-cloudwatch.md)。
此記憶體密集執行個體專為在雲端執行大型記憶體內資料庫而設計，包括 SAP HANA 記憶體內資料庫的生產部署。若要將 EBS 效能最大化，請使用具有偶數數量 `io1` 或 `io2` 磁碟區且有完全相同佈建效能的高記憶體執行個體。例如，對於 IOPS 繁重的工作負載，使用具有 40,000 個佈建 IOPS 的四個 `io1` 或 `io2` 磁碟區，以獲得最大 160,000 個執行個體 IOPS。同樣地，對於輸送量繁重的工作負載，使用具有具有 48,000 佈建 IOPS 的六個 `io1` 或 `io2` 磁碟區，以獲得最大 4,750 MB/s 輸送量。如需其他建議，請參閱 [SAP HANA 的儲存組態](https://docs.aws.amazon.com/sap/latest/sap-hana/hana-ops-storage-config.html)。
**考量事項**
+ 2020 年 2 月 26 日之後推出的 G4dn、I3en、Inf1、M5a、M5ad、R5a、R5ad、T3、T3a 和 Z1d 執行個體可提供最大的 EBS 最佳化效能。若要從 2020 年 2 月 26 日之前啟動的執行個體獲得最大效能，請停止並啟動該執行個體。
+ 2019 年 12 月 3 日之後推出的 C5、C5d、C5n、M5、M5d、M5n、M5dn、R5、R5d、R5n、R5dn 和 P3dn 執行個體可提供最大的 EBS 最佳化效能。若要從 2019 年 12 月 3 日之前啟動的執行個體獲得最大效能，請停止並啟動該執行個體。
+ `u-6tb1.metal`、`u-9tb1.metal`、`u-12tb1.metal` 以及 2020 年 3 月 12 日之後推出的執行個體可提供最大的 EBS 最佳化效能。2020 年 3 月 12 日之前推出的這些類型執行個體可能會提供較低的效能。若要從 2020 年 3 月 12 日之前啟動的執行個體獲得最大效能，請聯絡您的客戶團隊以免費升級該執行個體。

# 針對 Amazon EC2 執行個體啟用 EBS 最佳化
您僅能為上一代可選擇支援 EBS 最佳化的執行個體類型手動啟用該功能。如果您為這些執行個體類型啟用 EBS 最佳化，需支付[額外的每小時費用](https://aws.amazon.com/ec2/previous-generation/#EBS-optimized_instances)
**先決條件**
+ 確認該執行個體類型是否需要您啟用 EBS 最佳化。如需詳細資訊，請參閱[支援 EBS 最佳化](ebs-optimized.md#previous)。
+ 若要在啟動後啟用 EBS 最佳化，您必須停止執行個體。
**警告**
當您停止執行個體時，執行個體存放磁碟區上的資料會遺失。若要保留此資料，請將其備份至持久性儲存。
------
#### [ Console ]
**若要在啟動期間啟用 Amazon EBS 最佳化**
在啟動執行個體精靈中，選取所需的執行個體類型。展開**進階詳細資訊**區段，然後對於 **EBS 最佳化執行個體**，選取**啟用**。
如果所選執行個體類型不支援 Amazon EBS 最佳化，則會停用下拉式選單。如果執行個體類型預設為 Amazon EBS 最佳化，則已選擇啟用。
**若要在啟動後啟用 Amazon EBS 最佳化**
1. 前往 [https://console.aws.amazon.com/ec2/](https://console.aws.amazon.com/ec2/) 開啟 Amazon EC2 主控台。
1. 在導覽窗格中，選取 **Instances (執行個體)**，然後選取該執行個體。
1. 停止執行個體。依序選擇 **Actions (動作)**、**Instance state (執行個體狀態)**、**Stop instance (停止執行個體)**。
1. 在仍然選取執行個體的情況下，選取 **Actions (動作)**、**Instance settings (執行個體設定)**、**Change instance type (變更執行個體類型)**。
1. 選取 **EBS最佳化**，然後選擇**套用**。
如果執行個體類型預設為 Amazon EBS 最佳化，或不支援 Amazon EBS 最佳化，則會停用核取方塊。
1. 重新啟動執行個體。選擇 **Instance state (執行個體狀態)**、**Start instance (啟動執行個體)**。
------
#### [ AWS CLI ]
**若要在啟動期間啟用 Amazon EBS 最佳化**
請使用 `--ebs-optimized` 選項並搭配 [run-instances](https://docs.aws.amazon.com/cli/latest/reference/ec2/run-instances.html) 命令。
**若要在啟動後啟用 Amazon EBS 最佳化**
1. 如果執行個體正在執行中，使用 [stop-instance](https://docs.aws.amazon.com/cli/latest/reference/ec2/stop-instances.html) 命令來停止它。
```
aws ec2 stop-instances --instance-ids i-1234567890abcdef0
```
1. 使用 [modify-instance-attribute](https://docs.aws.amazon.com/cli/latest/reference/ec2/modify-instance-attribute.html) 命令並搭配 `--ebs-optimized` 選項來啟用 EBS 最佳化。
```
aws ec2 modify-instance-attribute \
--instance-id i-1234567890abcdef0 \
--ebs-optimized
```
------
#### [ PowerShell ]
**若要在啟動期間啟用 Amazon EBS 最佳化**
使用 [New-EC2Instance cmdlet](https://docs.aws.amazon.com/powershell/latest/reference/items/New-EC2Instance.html) 搭配 `-EbsOptimized` 選項。
**若要在啟動後啟用 Amazon EBS 最佳化**
1. 如果執行個體正在執行中，請使用 [Stop-EC2Instance](https://docs.aws.amazon.com/powershell/latest/reference/items/Stop-EC2Instance.html) cmdlet 來停止它。
```
Stop-EC2Instance -InstanceId i-1234567890abcdef0
```
1. 使用 [Edit-EC2InstanceAttribute](https://docs.aws.amazon.com/powershell/latest/reference/items/Edit-EC2InstanceAttribute.html) cmdlet 搭配 `-EbsOptimized` 選項來啟用 EBS 最佳化。
```
Edit-EC2InstanceAttribute `
-InstanceId i-1234567890abcdef0 `
-EbsOptimized $true
```
