第5世代 AMD EPYCTMプロセッサを搭載した Oracle Cloud Infrastructure (OCI) Compute E6 Standard が発表されました。
ストレージ技術基礎より、ストレージの IOPS(Input Output Per Second) と スループット(データ転送速度)の算出は次のようになります。
[スループット] = [1回のアクセスで処理する容量] × [IOPS]
--> 200Gbps = 4KB × IOPS
--> IOPS = 200Gb / 4KB = 25GB / 4 KB = 25,000,000 KB / 4 KB = 6,250,000
ということで 200Gbps の帯域幅を備えた BM.Standard.E6 コンピユートのストレージ・パフォーマンスは、625万 IOPS出そうです。
E6 Standard Bare metal instance は、高スループットのコンピュート集中型のワークロード向けに設計されています。各インスタンスには、256コア、3 TBのメモリ、200 Gbpsのネットワーク・スループットが付属しています。これは、E5 Standardと比較して、コンピュートおよびメモリーが33%多く、ネットワーク帯域幅が2倍であり、業界標準のベンチマークで最大2倍のパフォーマンスを実現します。
オラクルのワークロード・テストでは、E6 Standardは、E5 Standardよりも最大2倍のコア当たりパフォーマンスが向上し、コストを損なうことなく必要なコンピュート・パワーが得られます。

E6 Standardインスタンスの理想的なユース・ケース
・ ビデオ・トランスコーディング、会議、オンデマンド・ビデオ
・ 大規模なパラレル・バッチ・ジョブ
・ インメモリー・データベースとキャッシュ・フリート
・ エンタープライズ・アプリケーション用のバックエンド・サーバー
・ Webサーバーとアプリケーション・サーバー
・ ゲーム・サーバー
・ アプリケーション開発環境
・ ビッグ・データ処理 (Spark、Hadoopなど)
・ 財務モデリングとリアルタイム分析
・ 高パフォーマンス・コンピューティング (HPC)
・ 科学的シミュレーションと3Dレンダリング
ということで、Oracle Cloud Infrastructure (OCI) BM.Standard.E6 で IOパフォーマンス 600万IOPS, 200Gbpsスループットを手段問わず無邪気にだしてみてみてみます。
■ 超高パフォーマンス・ボリュームのためのアタッチメントの構成
超高パフォーマンス・レベルで構成されたボリュームをアタッチして、最適なパフォーマンスを実現するには、ボリューム・アタッチメントをマルチパス対応にする必要があります。
ブロック・ボリューム・サービスでは、ボリュームをアタッチする際に、アタッチメントがマルチパス対応になるよう試行します。満たしていない前提条件があると、ボリューム・アタッチメントはマルチパス対応になりません。
● マルチパス対応の iSCSI アタッチメント前提条件
マルチパス対応の iSCSI ボリュームアタッチメントを構成するために必要な前提条件
・参考: 超高パフォーマンス・ボリュームのためのアタッチメントの構成
- サポートされているシェイプ
- サポートされてるイメージ
- インスタンスのブロック・ボリューム管理プラグインを有効化
- ブロック・ボリューム管理プラグインのパブリックIPアドレスまたはサービス・ゲートウェイを設定
- 権限の構成
- 一貫性のあるデバイス・パスを使用
- インスタンスに、同じインスタンスの別のマルチパス対応アタッチメントが存在しないこと(Oracle Cloud Agentバージョン1.39未満の場合)
■ 権限の構成
ブロック・ボリューム管理プラグインが、マルチパス対応iSCSIアタッチメントの iSCSI設定の結果をレポートできるよう、権限を構成する必要があります
1) 動的グループの作成
次のコード・サンプルの一致ルールを使用して動的グループを作成し、指定したコンパートメント内のすべてのインスタンスを追加します。
ここでは、UHP_Dynamic_Group という名前で作成
例)
ANY {instance.compartment.id = '<テナンシOCID>', instance.compartment.id = '<コンパートメントOCID>'}
2) 動的グループのポリシーの構成
前のステップで作成した動的グループ: UHP_Dynamic_Group に権限を付与するポリシーを構成して、インスタンス・エージェントによるアクセスを可能にし、ブロック・ボリューム・サービスをコールして、アタッチメント構成を取得できるようにします。
例)
Allow <dynamic-group名> InstantAgent to use instances in tenancy
Allow <dynamic-group名> InstantAgent to use volume-attachments in tenancy
■ サービス・ゲートウェイとルート制御設定
コンピュート・インスタンスが Oracleサービス (OCN) にアクセスできるよう
サービス・ゲートウェイを作成して、インスタンス配置するサブネットの ルート・ルールへ「 All Oracle Services Network Service」を設定します。
1) Serive Gateway設定
2) Route Table設定
Compute配置するSubnetに付属の Route Table へ Service Gatewayへ通じるRoute Rouleを設定
■ コンピュート・インスタンス作成
1) OCIコンソール画面
メニューから [コンピュート] > [インスタンス] をクリック
2) インスタンス画面
[インスタンス作成]をクリック
3) コンピュート・インスタンスの作成画面
今回、BM.Standard.E6 を使用して UHPブロック・ボリュームのマルチパス有効化するために 以下項目を設定して作成します。
・サポートされているシェイプ: Oracle Linux 9
・サポートされてるイメージ: BM.Standard.E6
・インスタンスのブロック・ボリューム管理プラグイン: 有効化
・すべてのシェイプの参照画面
主に次の項目を設定して[Select Shape]をクリック
Instance type: 今回は、[Bare metal machine]を選択
Shape name: 今回は、[BM.Standard.E6.256]を選択
Provision only a percentage of cores and disable the rest: 192あるCPUから利用する％を指定します。
・コンピュート・インスタンスの作成: Basic画面
Oracle Cloud Agent項目で [ブロック・ボリューム管理]をチェック
4)コンピュート・インスタンスの作成: Review画面
全ての項目の入力項目を確認したら、[Create]をクリック
5) 作成中
6) 作成完了
7) Block Volume Management プラグイン確認
UHPのiSCSIを自動認識するようにBlock Volume Management プラグインが有効化されていることを確認
● 複数 UHPボリューム・サポート確認
Oracle Cloud Agentバージョン1.39以降のインスタンスでは、複数の超高パフォーマンス・ボリュームがサポートされています。次のコマンドを使用して、バージョンを確認します。

#
# For a list of configuration options with descriptions, see the multipath.conf

## By default, devices with vendor = "IBM" and product = "S/390.*" are

## following lines.
#blacklist_exceptions {
# device {
# vendor "IBM"
# product "S/390.*"
# }
#}
## Use user friendly names, instead of using WWIDs as names.
defaults {

## Here is an example of how to configure some standard options.

## The wwid line in the following blacklist section is shown as an example
## of how to blacklist devices by wwid. The 2 devnode lines are the
## compiled in default blacklist. If you want to blacklist entire types
## of devices, such as all scsi devices, you should use a devnode line.
## However, if you want to blacklist specific devices, you should use
## a wwid line. Since there is no guarantee that a specific device will
## not change names on reboot (from /dev/sda to /dev/sdb for example)
## devnode lines are not recommended for blacklisting specific devices.
##

● IOPS パフォーマンス・テスト
IOPSパフォーマンスをテストするには、次のFIOサンプル・コマンドを使用します。コマンドを直接実行することも、コマンドを使用してジョブ・ファイルを作成してからそのジョブ・ファイルを実行することもできます。
・参考: Sample FIO Commands for Block Volume Performance Tests on Linux-based Instances
FIO実行するときは--numjobs オプションを使用して、ストライプしているデバイス(/dev/sd?)の数に応じて並列度を上げて実行します。
今回100個のデバイス・ファイルがあるので、10以上の値で調整します。
・ Sequential Reads テスト
データベース・ワークロードなど、順次アクセス・パターンを利用できるワークロードに対しては、順次読取りをテストすることにより、このパターンのパフォーマンスを確認できます。
順次読取りをテストするには、次のコマンドを実行します。
[root@bm-e6 ~]# fio --filename=/dev/volgroup01/striped_logical_volume --direct=1 --rw=read --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=150 --time_based --group_reporting --name=iops-test-job --eta-newline=1 --readonly
