Dell Unity：透過 Unisphere CLI 管理 FAST VP 自動分層重新安置

• 提供透過 Unisphere CLI （UEMCLI） 在 Unity 混合式儲存集區中管理自動階層式相關資訊
• 簡要說明 FAST VP

• Fast VP 會監控分層式集區中資料的使用方式。分層式集區是異質集區，配置有多個磁片磁碟機類別 （SAS Flash 2 或 SAS Flash 3，外加 SAS 或 NL-SAS）。
• 根據分層原則，使用監控統計資料自動將資料區塊 （256 MB 精細） 重新放置至集區內的其他階層。 
• 在分層式和非層級集區中的磁片磁碟機上執行負載平衡

• 檢視系統 FAST VP 資訊：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/fastvp show -detail

Storage system address: 10.0.0.1
Storage system port: 443
HTTPS connection

1: Paused = no
Schedule enabled = yes
Frequency = Every Mon, Fri at 22:30 until 8:00
Rate = high
Data to move up = 4947802324992 (1.5T)
Data to move down = 4947802324992 (1.5T)
Data to move within = 4947802324992 (1.5T)
Estimated scheduled relocation time = 7h 30m

• 編輯系統 FAST VP 資訊：

Format :
uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/fastvp set [-schedEnabled {yes | no}] [- days ] [-at ] [-until ] [-rate {low | medium | high}] [-paused {yes | no}]

For example, the following command changes the data relocation schedule to run on Mondays and Fridays from 23:00 to 07:00:
uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/fastvp set -schedEnabled yes -days "Mon,Fri" -at 23:00 -until 07:00

• 檢視集區 FAST VP 設定：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/ fastvp –show -detail
Storage system address: 10.0.0.1
Storage system port: 443
TTPS connection

1: Pool = pool_1
Relocation type = manual
Status = Active
Schedule enabled = no
Start time = 2013-09-20 12:55:32
End time = 2013-09-20 21:10:17
Data relocated = 100111454324 (100G)
Rate = high
Data to move up = 4947802324992 (4.9T)
Data to move down = 4947802324992 (4.9T)
Data to move within = 4947802324992 (4.9T)
Data to move up per tier = Performance: 500182324992 (500G), Capacity: 1000114543245 (1.0T)
Data to move down per tier = Extreme Performance: 1000114543245 (1.0T), Performance: 500182324992 (500G)
Data to move within per tier = Extreme Performance: 500182324992 (500G), Performance: 500182324992 (500G), Capacity: 500182324992 (500G)
Estimated relocation time = 7h 30m

• 編輯集區 FAST VP 設定，使其遵循系統層級排程或不執行 （使其處於手動重新配置中）：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/fastvp {-pool | -poolName } set -schedEnabled {yes | no}

• 在集區上開始資料移轉：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/fastvp {-pool | -poolName } start [-rate {low | medium | high}] [-endTime ]

Default rate is medium
Default end time is 8 hours after start
If you want to edit the end time, add the time in HH:MM format

• 停止集區上的資料重新安置：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/fastvp {-pool | -poolName } stop
