Amazon FSx for NetApp ONTAPにおけるSnapMirrorの同時転送数の上限を確認してみた
最大同時転送数やボリューム数、SnapMirrorによる負荷を考慮した上で実行間隔を決定しよう
2023.12.30SnapMirrorで同時にいくつ転送できるか気になる
こんにちは、のんピ(@non____97)です。
皆さんはAmazon FSx for NetApp ONTAP(以降FSxN)におけるSnapMirrorの最大同時転送数が気になったことはありますか? 私はあります。
SnapMirrorの最大同時転送数が少なければ、大量のボリュームの移行やバックアップをするときに時間がかかりそうです。
SnapMirrorの同時転送数の上限はプラットフォームの種類やONTAPのバージョンによって異なるようです。具体的な値は以下NetAppのTRに記載がありました。
同時レプリケーション処理数
同時に実行できるSnapMirror処理数には制限があります。この制限はノードごとに設定され、プラットフォームの種類およびData ONTAPのバージョンによって異なります。ノードモデルごとに許可される同時SnapMirror処理数については、「NetApp Hardware Universe」を参照してください。
ただし、プラットフォームの種類に Amazon FSx for NetApp ONTAP はありません。
風の噂によると32らしいです。
本当に32なのか自分の目で確認してみます。
いきなりまとめ
- 検証した限り、2023/12/30時点のAmazon FSx for NetApp ONTAP(ONTAP 9.13.1P5)におけるSnapMirrorの同時転送数の上限は100
- 同時転送数の上限以上のリクエストは拒否されるのではなくキューに入れられ、転送を待機する
- SnapMirror relationshipは105以上作成可能
やってみた
検証環境
検証環境は以下のとおりです。
どちらのFSxNファイルシステムもONTAP 9.13.1P5です。

クラスターピアリングの作成
まず、クラスターピアリングをします。
その前にFSxNファイルシステムのLIFのIPアドレスを確認します。

FSxN 2からクラスターピアリングを作成します。
::> cluster peer create -peer-addrs 10.0.8.123 10.0.8.84
Notice: Use a generated passphrase or choose a passphrase of 8 or more characters. To ensure the authenticity of the peering relationship, use a phrase or
sequence of characters that would be hard to guess.
Enter the passphrase:
Confirm the passphrase:
Notice: Now use the same passphrase in the "cluster peer create" command in the other cluster.
FSxN 1からもクラスターピアリングを作成します。

SVMピアリングの作成
続いて、SVMピアリングを行います。
FSxN 1からSVMピアリングを作成します。

snapmirror svm
40個同時にSnapMirror Initialize
それではSnapMirrorを行います。
噂によるとFSxNのSnapMirrorの最大同時転送は32らしいので、それを超える40で試します。
全SnapMirrorの転送元ボリュームはFSxN 1のsvm上のvol1とします。
snapmirror protectを40回入力するのも大変なので、シェルスクリプトで実行するコマンドを書き出します。
$ for i in {01..40}; do
echo "snapmirror protect -path-list svm:vol1 -destination-vserver svm_fsxn2 -policy MirrorAllSnapshots -auto-initialize true -support-tiering true -tiering-policy none -destination-volume-suffix _dst${i}"

じわじわとSnapMirror relationshipが作成され、転送が開始されています。
このままだと初めの方に転送を開始したものが転送終了してしまいそうです。FSxN 1のSnapMirrorrのグローバルスロットリングを調整して、転送速度を落とします。

40個のSnapMirror全て同時に転送されていそうです。
同時転送数の上限32個の噂は気のせいだったかもしれません。
65個同時にSnapMirror Initialize
次に制約があるとしたら64でしょうか。
65同時にSnapMirror Initializeしてみて、確認しましょう。

65個同時に転送できています。
同時転送数64の壁も突破しました。
さらに40個の転送元ボリュームを追加してSnapMirror Initialize
もしかして転送元ボリューム数が1つであるのがよくないのでしょうか。同時転送数の上限32というのは、同時に転送できる転送元のボリューム数の上限が32というのを指しているのかもしれません。
試しにSnapMirrorの転送元ボリュームとして40個のボリュームを追加します。
ボリューム作成用のコマンドをシェルスクリプトで書き出します。
$ for i in {01..40}; do
echo "volume create -vserver svm -volume vol${i} -aggregate aggr1 -size 4GB -state online -policy default -tiering-policy none -snapshot-policy none -junction-path /vol${i}"
done
volume create -vserver svm -volume vol01 -aggregate aggr1 -size 4GB -state online -policy default -tiering-policy none -snapshot-policy none -junction-path /vol01
volume create -vserver svm -volume vol02 -aggregate aggr1 -size 4GB -state online -policy default -tiering-policy none -snapshot-policy none -junction-path /vol02
volume create -vserver svm -volume vol03 -aggregate aggr1 -size 4GB -state online -policy default -tiering-policy none -snapshot-policy none -junction-path /vol03

volume create -vserver svm -volume vol39 -aggregate aggr1 -size 4GB -state online -policy default -tiering-policy none -snapshot-policy none -junction-path /vol39
volume create -vserver svm -volume vol40 -aggregate aggr1 -size 4GB -state online -policy default -tiering-policy none -snapshot-policy none -junction-path /vol40
書き出したコマンドをFSxN 1で実行します。実行後ボリュームが40個追加されていることを確認します。

追加したSnapMirror relationshipのうち35個はTransferringとなっているため、「同時に転送できる転送元のボリューム数の上限が32」という仮説は否定されました。

一部のSnapMirrorの転送が完了したからか、キューに溜まっていたsvm:vol34やsvm:vol37の転送が開始されましたね。
「同時に転送できる転送元のボリューム数の上限が35」なのか、「最大同時転送数が100」なのかの切り分け
先の検証で「同時に転送できる転送元のボリューム数の上限が35」なのか? というところが気になるところです。
しかし、35という値はあまりにもキリが悪いです。
それよりも、105個あるSnapMirror relationshipのうち5つ転送できないのであれば、最大同時転送数は100であると捉えるのが自然です。
切り分けるために一度SnapMirrorを流し切ります。
65個のSnapMirror relationshipの転送元ボリュームはTiering PolicyがAllであり、ほとんどのデータブロックがキャパシティプールストレージに存在しています。そのため転送速度が非常に低速です。
Tiering PolicyをNone、Cloud retrievalポリシーをPromoteに変更し、データをSSDに書き戻すことで読み込み速度を向上させます。
::*> volume modify -vserver svm -volume vol1 -cloud-retrieval-policy promote -tiering-policy none
Warning: The "promote" cloud retrieve policy retrieves all of the cloud data for the specified volume. If the tiering policy is "snapshot-only" then only AFS data
is retrieved. If the tiering policy is "none" then all data is retrieved. Volume "vol1" in Vserver "svm" is on a FabricPool, and there are approximately
9925271552 bytes tiered to the cloud that will be retrieved. Cloud retrieval may take a significant amount of time, and may degrade performance during
that time. The cloud retrieve operation may also result in data charges by your object store provider.

転送元ボリュームが40個あったとしても、SnapMirrorを同時に流すことができました。
そのため、SnapMirrorの同時転送数の上限は100であると考えます。多くのモデルでも同時転送数の上限は100で設定されているので違和感は特にありません。
最大同時転送数やボリューム数、SnapMirrorによる負荷を考慮した上で実行間隔を決定しよう
Amazon FSx for NetApp ONTAPにおけるSnapMirrorの同時転送数の上限を確認してみました。
大量のボリュームが存在する場合はこちらの上限の影響を受けるか意識しましょう。上限を超過するものはキューに溜まって転送されるといっても安心してはいけません。たとえば、5分間隔で100個超のボリュームをSnapMirrorで転送するとなると、キューに溜まっているものを捌き切ることができずトラブルの元になると考えます。
また、SnapMirrorによる負荷も見逃せません。システムに問題を与えない範囲で実行間隔を決定することをお勧めします。
この記事が誰かの助けになれば幸いです。
