µ¨ PERC H710p - fastpath¸¦ À§ÇÑ ¾÷±×·¹À̵å key Æijª¿ä?

   Á¶È¸ 23825   Ãßõ 0    

지난달에 DELL R620을 DB서버로 투입했는데,
아무래도 SSD의 속도가 IBM x 서버보다 아닌 것 같아서 fastpath를 체크해 봤습니다.
 
그런데 upgrade key가 없습니다.
cachecache는 되는데 그것은 SSD를 cache로 사용할때나 필요한 것이고
SSD를 직접 사용할 때 필요한 fastpath가 안되는 것 입니다.
 
델의 R620, R720의 견적을 봐도 upgrade key의 존재 자체가 없는데
PERC 710p를 위한 upgrade key를 파는지 아시는 분 계신가요?
내일 델 영업팀에 물어보기까지 너무 궁금 합니다.
 
fastpath가 안되면,
델 장비를 DB서버에서 철수하거나 raid를 LSI 수정으로 바꿔야 할 것 같은데
이런 황망스런 일이...

?Fastpath I/O is a method of increasing Input/Output Operations per Second (IOPS) by using the 2nd core of the PERC (Gemini core) to directly execute I/O and completely bypass caching.
?Fastpath I/O is most beneficial for SSD disks.
?Fastpath I/O is not available on H710 controller, only available on H710P and H810 controllers.
?Fastpath I/O is automatically available on eligible VDs.

Fastpath eligible VDs should have the following properties:
?Write-Through
?No Read Ahead
?No Background Operation (e.g. Background Initialization, Patrol Read or Consistency Check ) in progress.
