오토레이트 질문입니다 급해요

[박선호_1]

arraydsp 로 해서..

12h 정보를 보면....

세팅값중에...



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

SDTR = ENABLED

WDTR = 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

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....

12H의 default setting중에 read cache는 DISABLED입니다.



Read Cache DISABLED



Indicates whether the disk array should cache read data.

Note: This field does not represent what is actually

happening. The disk array uses read cache algorithms.

This field is put in place to facilitate some third party

operating systems.
