  3. Terminal Terminal Terminal Terminal Terminal Terminal Terminal Terminal 電腦應用趨勢主機系統時代 - 強調計算能力 Main Frame

  4. 電腦應用趨勢網路通訊時代 - 強調主從架構 Client Server Client Server Network Client Server Client Client

  5. 電腦應用趨勢儲存應用時代 - 強調資料安全 AP Server AP Server AP Server AP Server AP Server AP Server AP Server AP Server

  6. 資料儲存應用傳統分散式架構 - DAS file server mail server web server Disk 達極限 無法擴充 缺點: - 每台主機各自擁有disk/array, 無法統一規劃應用,形成浪費。 - 單一主機之 disk/array 擴充受限於主機規格。 - 每一主機之 disk/array 容錯性較低。若全部採用高階array, 則成本太高。 Space 不夠 Space 閒置 99% 30% Client Client Client Client

  7. 資料儲存應用網路集中式架構 - NAS 缺點: - 單一NAS/iSCSI array 之disk 擴充受限於本機規格。 - iSCSI 目前其他解決方案 ( backup, replication etc. ), 未成熟。 iSCSI array ( block level ) NAS server ( file level ) Disk 達極限, 仍無法擴充 Disk 達極限, 仍無法擴充 Client Client Client Client

  8. 資料備份應用傳統分散式架構 - Local Backup 缺點: - 備份軟硬體投資成本太高. - 分散式備份不易管理,磁帶無法統一規劃應用。 file server mail server web server Client Client

  9. 資料備份應用網路集中式架構 - LAN Backup 缺點: - 備份佔用data LAN 頻寬。 file server mail server web server data LAN Tape Library Client backup server

  10. 資料備份應用網路集中式架構改良 - 獨立備份網路 backup LAN Client Client data LAN file server mail server web server Tape Library backup server

  11. 儲存應用的挑戰 • disk/array之整體規劃應用 - storage 無法共享,有礙於整體規劃應用 - data 成長太快,storage 之擴充性受限 - 資料之複製, 移轉 ( migration ) 等應用 • 資料之快速備份,完善之備份管理 - 資料量太大, backup window 太小 - 7x24 AP server 無down time • 異地備援 - tape & disk 資料異地儲存

  12. 儲存應用解決方案新架構 + 軟體功能支援 • 新架構: 集中化管理Consolidation - SAN ( Storage Area Network ) • 軟體功能支援: 虛擬化Virtualization - mirror - snapshot copy, point-in-time copy - replication • 軟體功能支援:Backup - LANfree / Serverless backup

  13. 儲存架構DAS ( Direct Attached Storage ) local backup 缺點: - SCSI cable 長度限制, 影響機房佈局。 - SCSI daisy-chained 之 device 數目與cable 長度受限。 - local backup 不易管理schedule & tape。 AP/file server SCSI backup server SCSI Client Client Client Client

  14. 儲存架構 NAS ( Network Attached Storage ) NDMP backup LAN backup 缺點: - 單一NAS/iSCSI 主機之disk 擴充受限於本機規格。 - iSCSI/low-end NAS 目前無其他解決方案 ( backup, replication etc. ). - LAN backup 佔用data LAN 頻寬。 iSCSI array ( block level ) NAS server ( file level ) file system mail web disk partition SCSI data LAN SCSI Client file server mail server web server

  15. 儲存架構SAN ( Storage Area Network ) LAN backup backup server backup server A B C SAN backup A B C Client Client data LAN file server mail server web server storage LAN tape library disk array ( block level )

  16. SAN 的迷思SAN is Fiber? F/C switch ether switch SCSI RAID SCSI RAID F/C RAID F/C RAID F/C router SCSI tape SCSI tape IP SAN Server ethernet Client Client fiber SCSI data LAN AP server AP server FC SAN IP SAN

  17. 有何不同 ? SAN 的迷思SAN一定要完全consolidate, 才能達到真正的共享? 不夠再加 新array 還是得加 新array 數個中高階array : - 先保留短中期容量 超大高階array : -保留長期容量, 慢慢擴充…. - 但,不夠了怎麼辦 !!

  18. Why SAN? • consolidation 集中規劃管理 - 擺脫SCSI 長度限制 - device ( disk/tape ) 共享 - device 可採用高階產品,減低down time - 架構延展性佳,易擴充 • Dedicate storage LAN • SAN 是基礎建設,可“搭建”其他解決方案 - storage virtualization - SAN backup

  19. storage pool A 甲 B 乙 D C logical volume Storage VirtualizationStorage Pool physical disk/array volume

  20. Storage VirtualizationMirror 繼續read/write primary mirrored FAIL I/O

  21. Storage VirtualizationSnapshot Copy 10:00 snapshot 10:00 status snapshot I/O I/O 持續異動 source copied

  22. Storage VirtualizationPoint-in-time Copy 10:00 1st snapshot full 10:00 status 11:00 2nd snapshot incr. 11:00 12:00 3rd snapshot snapshot incr. 12:00 I/O 持續異動 source

  23. Storage VirtualizationPoint-in-time Recover full 10:00 status source incr. 11:00 snapshot incr. 12:00 I/O restore to 10:00 restore to 11:00 restore to 12:00

  24. Storage VirtualizationReplication source replicating sync. or async. local site remote DR site Internet or leased line

  25. Storage VirtualizationDisaster Recovery FAIL source replicated recover O.S. & DB local site remote DR site

  26. READY new volume DR volume sync. or async. Storage VirtualizationRecover local site remote DR site Internet or leased line

  31. SANAStor 系統功能 Dual-active HA Data LAN AP server AP server SANclient Dynapath SANclient Dynapath Client Active Active Client SANAStor controller 1 SANAStor controller 2 Client • HA 支援Auto-Failover. • Dynapath Agent支援Dual-Active架構, AP Server資料傳輸具備Load-Balancing 以及Security功能 。

  32. SANAStor 系統功能 SAN+NAS+IP SAN Data LAN AP server AP server AP server Fiber channel IP SAN Client FC SAN client FC SAN client FC SAN client Ethernet NAS Client SAN volume ( SAN path ) NAS volume ( data LAN path ) NAS Client • 同一個 SANAStor 可共存 SAN Volume 及 NAS Volume

  33. Source mirroring Source Source image at 10:00 SANAStor 系統功能 Volumes Mirroring and Snapshot Copy I/O writing from SAN client or NAS client SANAStor Mirroring Primary Secondary Snapshot copy issued at 10:00 • 在實體資料複製前, Snapshot Copy 功能將會針對Source Volume 做快照(Snapshot).

  34. 9:00 9:00 10:00 10:00 Source 11:00 11:00 12:00 12:00 SANAStor 系統功能 Point-in-Time Copy and Viewer SANAStor AP server Point-in-Time Copy at 9:00 Point-in-Time Copy at 10:00 AP server Point-in-Time Copy at 11:00 AP server Point-in-Time Copy at 12:00 Snapshot Volume ( can't be mounted ) for Point-in-Time Copy Mounted Virtual Volume for Point-in-Time Viewer

  35.

Snapshot Replication 複製功能將資料複製至DRC端 2. Point-in-Time Copy機制運作 3. 若Local端Fail, DRC Volume會提供讓Failed Local 端所有Device使用 4. 當Local Volume 修復後,再將DRC Volume 回複至Local 端

  36. Why SANAStor ? 問題 1: 想整合SAN + NAS ? • 在IT環境, 您將會有SAN 與NAS的需求。 • 針對管理統合的議題,您一定會有儲存整合需求。 • 之後您會遇到的困難... AP server Client Client Client FC switch NAS Consolidation SAN Consolidation 分散式架構造成操作方式與管理方式上的差異!!!

  37. NAS vol. SAN vol. NAS vol. SAN vol. Why SANAStor? 解決方案 1: 完全的儲存架構整合 AP server NAS Client NASClient IP SAN Client NAS Client IP SAN Client SANAStor Full Consolidation • Benefit • 統合 SAN + NAS 儲存架構 • 統合儲存管理

  38. Why SANAStor ? 問題 2: 遭遇虛擬儲存限制的困境? • 在IT環境,資料成長快速。 • 當您的儲存設備Disk Array不敷使用時,您必須再添購一台。 • 之後您會遇到的困難... New array Mirror Mirror 您無法整合運用新的Disk Array 儲存空間來做虛擬化整合 !!!

  39. Why SANAStor ? 解決方案 2: 無限擴充虛擬儲存容量 SANAStor 1 SANAStor 2 Mirror Mirror SANAS LAN • Benefit • 同時具備彈性與擴充性

  40. Why SANAStor ? 問題 3: 高成本的Replication功能建置? • 針對企業之永續經營,異地備援是非常重要的. • 但Storage-Base /Server-Base Replication方案則相當昂貴. Disaster Recovery Center AP server FC switch FC switch Leased line Gateway Gateway 您需要建置兩套High-End Array ( 且須相同型號/模組 ), 以及昂貴的Gateway. 且您無法執行多對一(DRC)資料Replication.

  41. Why SANAStor ? 解決方案 3: 透過TCP/IP來執行Replication Disaster Recovery Center SANAStor WAN over TCP/IP Entry SANAStor High-End SANAStor • Benefit • 具成本效益,不須同時建置兩套High-End SANAStor • 不需要Gateway • 在DRC端同時運作Point-in-Time Copy即時回復功能 • 支援多對一(DRC)資料Replication
