RaidGroupA RAID4 set with at least two disks: data & parityORA RAID-DP set with at least three disks: data and 2 parity.Either type raidroup can grow additional disks instantly while online.

AggregateA collection of one or more raidgroups, used as a container to provision one or more flexvols.

FlexVol (flexible volume) A formatted filesystem allocated as a logical subset of the available space (4KB blocks) within an aggregate.

Flexibly Extend

即時動態線上檔案系統擴充能力

屬於 Dynamic Online File System Growth最少可一次增加 ( 減少 ) 數 MB 的容量最多可一次增加 ( 減少 ) 數 TB 的容量 不需等待就能立刻使用新增的容量不影響系統運作及效能不需重建檔案系統對 Unix 而言 -- 不需更動 mount point 的設定對 Windows 而言 -- 不需更動網路磁碟的設定

即時動態線上檔案數量上限擴充能力

在檔案系統容量不變的前提下，可隨時增加 inode 數量 ( 可容納的最大檔案數量 )

避免因檔案數量達到 Volume 的系統上限時，即使仍有剩餘儲存空間，也無法再存入檔案了完全不影響系統運作

即時動態線上目錄檔案數量上限擴充能力

因為單個目錄檔案數量太多會影響效能，故 Filer 上針對每個 Volume 有一個 MaxDirSize option預設目錄檔案數量限制是 System Memory 的 1%10240KB 為目錄可容納檔案數量為 300,000

NetApp RAID Structure

RAID 的歷史

RAIDUniversity California at Berkeley in 1987早期： Redundant Array of Inexpensive Disks現在： Redundant Array of Independent Disks

RAID 的目標更大的容量 (capacity)更高的效能 (performance)更佳的可靠度 (reliability)更高的可用度 (availability)

RAID levels ：0 : Striping (No protection)1 : Mirroring2 : ECC bit-level checksum3 : Byte-level striping dedicated parity disk (single user)4 : Block-level striping dedicated parity disk (multi user)5 : Block-level striping distributed parity disk (multi user)

Level 3,4,5 Algorithms : XOR (Exclusive OR)

RAID 0 – Striping

將所資料打散在所有硬碟上面效能最高任何一顆硬碟故障所有資料就會流失無資料安全保護功能，風險性比單顆硬碟更高

* RAID 0 – NetApp not support

RAID 1 – Mirroring

RAID 4 – Striping + Single Parity Drive

能防止任何一顆硬碟故障而導致資料流失 ( 包括 Parity)將資料經過 XOR 的運算值寫入某個特定的 Parity 硬碟Stripe 的單位 : Block Level適合多人工作環境讀取效能佳標準的設計上 Parity 硬碟成為寫入效能上的瓶頸
