arraydsp 로 해서..

12h 정보를 보면....


read cache disable 로 되있는데요..

Array configuration:

Active Hot Spare Desired = ENABLED

Auto Include = ENABLED

Auto Rebuild = ENABLED

Rebuild Priority = HIGH

Capacity Depletion Threshold = 0%

Write Working Set Interval = 8640 seconds

Language = ENGLISH

Log Full Warning = DISABLED

Volume Set Partitioning = DISABLED

Format Pattern Fill = DISABLED

Subsystem Type ID = 12

LUN Creation Limit = 8

Maximum LUN Creation Limit = 8

Array SCSI configuration:

Controller X SCSI Address = 1

Controller Y SCSI Address = 0

Write Cache = ENABLED

Read Cache = DISABLED -->이부분..

SCSI Parity Checking = ENABLED



Terminator Power = ENABLED

Unit Attention = ENABLED

Disable Remote Reset = ENABLED

Secondary Controller Offline = DISABLED

Very Early Busy = DISABLED

Queue Full Threshold = 1952

Maximum Queue Full Threshold = 1952

Simplified Resiliency Setting = Normal

Disable NVRAM on WCE False = FALSE

Disable NVRAM with One Ctrlr = TRUE

Disable NVRAM on UPS absent = FALSE

Force Unit Access Response = 0

Disable Read Hits = FALSE

Resiliency Threshold = 4

제가 생각 할때는...read cache 부분이 enable 로 되있으면

실제 데이타를 사용할때..속도도 빨라지고..퍼포먼스도

좋아질꺼 같은데....제 생각이 틀린건가요....

원래 이부분이 disable이 맞는건지요?

여튼 빠른 답변좀 부탁드립니다....
