1 EMC INFRASTRUCTURE FOR VIRTUAL DESKTOPS Enabled by EMC VNX VMware vsphere 4.1, VMware View 4.5, and VMware View Composer 2.5 聚碩科技股份有限公司主題 : 企業虛擬桌面的儲存規劃與應用 Technical Presentation 主講人 : 林立棕

2 VDI 應用趨勢 EMC VNX VDI 架構設計考量內容 EMC VNX FAST 在 VDI 應用效益結論及建議

3 VDI 應用趨勢

4 The Journey to the Private Cloud Percent Virtualized IT PRODUCTION BUSINESS PRODUCTION 85% IT-AS-A-SERVICE 95% 50% 30% 15% Platinum Gold Lower costs Improve quality of service Improve agility

5 VDI 演進

7 The Cloud is Changing Computing Environments Data Apps Computing Public Cloud Data Apps Computing Data Apps Interaction 連線裝置 Private Cloud

8 滿意嗎?

9 VDI 建置成本 24% 41% 8% 8% 1% Source: Gartner Dataquest

10 VDI 的應用對 IOPS 影響 Complexity Task Workers Knowledge Workers Power Users Mobile Users Terminal Services VDI, Application Virtualization VDI, Application Virt., Client Virt.

11 VDI 架構成功的關鍵因素現有的虛擬化建議架構都是為了 Server Virtualization 設計的小小的更動, 大大的影響 IOPS per desktop multiplies RAM kills 每 1 GB RAM 需要 2GB 的儲存空間對於穩定性的要求和 Server 虛擬化一樣效能要求比 Server 虛擬化更高! 常見的規劃迷失過度低估儲存的需求 IOPS not Capacity When is this exposed? 開機風暴 (Boot Storm) Antivirus Application Patching

22 VDI 架構設計考量

23 架構設計考量 Design considerations Processor Memory Disk Network

24 架構設計考量 Processor Baseline load 9% Single vcpu 10 VMs per core VMs per core with hyper-threading Eight host per cluster Plan for 7 while considering High Availability

25 架構設計考量 Disk Baseline 9 IOPS average 為開機和登入估算 10~20 倍的 IO 量 65% 讀取動作和 35% 寫入動作開機 9:1 多種硬碟規格的整合 4 SAS drives = 9 NL-SAS drives 125 SAS drives = 9 EFDs 125 NL-SAS drives = 4 EFDs Device IOPS Interface 7,200 rpm SATA drives ~ IOPS [2] SATA 3 Gb/s 10,000 rpm SATA drives ~ IOPS [2] SATA 3 Gb/s 15,000 rpm SAS drives ~ IOPS [2] SAS

26 架構設計考量 Disk ( 續 ) 儲存空間節省技術 VMware linked clone Thin provisioning VAAI 讓 1 個 LUN, 支援 512 虛擬機為下列的動作考慮額外的硬碟空間 Replica, Delta disk, twice the virtual machine memory size, disposable disk, log, internal disk, and swap Hot Spare

29 Boot storm Login VSI Anti-virus 測試和驗證

30 測試和驗證 Boot storm 利用 vspher Client 將 2,000 virtual machines 開機 EMC FAST Cache 減少了 95 percent read I/O:

31 測試和驗證 Boot storm 利用 vspher Client 將 2,000 virtual machines 開機 EMC FAST Cache 減少了 64 percent Write I/O:

32 測試和驗證 Login VSI 使用 Login VSI medium workload 測試, 我們發現磁碟回應時間低於 4 ms

33 測試和驗證 Login VSI The FAST Cache serviced more than 90 percent for read and write I/O:

34 測試和驗證 Anti Anti-virus Using a McAfee Enterprise anti-virus scanner, we performed an on demand scan on a pool of 100, 200, and 300 virtual machines. The average times to perform the anti-virus scan are:

35 測試和驗證 Anti-virus The FAST Cache hit ratios 100, 200, and 300 virtual machine data scans are :

36 結論及建議以上的測試驗證了 : 藉由使用 FAST Cache 和 VMware VAAI, 2,000 桌面虛擬機從開機到可以使用, 減少了 25% 的時間在 FAST Cache Enabled LUN 使用 VMware Transparent Page Sharing, 發現在安裝 96G 實體記憶體的主機上, 減少了 92 GB 的記憶體使用. VAAI-enabled 的 \ 儲存系統, 讓單一 LUN 可以存放高達 512 virtual machines, 對照沒有 VAAI 的存儲系統只能放 64 virtual machines 使用 Flash as FAST Cache 減少了傳統硬碟使用數量, 並得到了更高的 IOPS
