PS6500 Storage Pools

Hello MightyJainesh,

I found an administrator guide please check page 31 for multiple pool design
"Dell EqualLogic Group Manager Administrator's Guide PS Series" https://dell.to/3P8jbob

In addition, I would like to share the links below that I think may be useful.
"PS Series technical white papers" https://dell.to/3nHVM1i

And adding setup guide "Dell EqualLogic PS6000 Storage Arrays - Installation and Setup Guide" https://dell.to/3P9EvtD

Hope that helps!

Thanks for the reply. I don't see any way with only a single member to be able to create pools based on disk types or sizes. 

Am I missing something? I would really like to avoid getting another member, just to separate the disks types/sizes.

Hello MightyJainesh,

You will need at least two members.

Members per pool :  2

Thanks. Is there no way to use single member and have different disk sizes?

If you mix capacity, in the array, it would limit the usable capacity of all drives to the smallest drive in the array.

You cannot mix SAS and SATA.

This may help:

Hello,  

 Just to confirm what's been said, pools are per member, no way to split a member into pools.  The RAID policy is per member.  No way to manually create multiple RAIDsets with select drives. Mixing of RPM speeds in the same member isn't supported either. 

If you have two 6500's and can fill them with 10K and the other with 7.2K the capacity and performance increase would be substantial.   If you mix them in the same pool, then most of the volume space will be on the much larger 7.2K drives.  Members in the same pool stripe data across them in perportion to their relative sizes. IOs will have to wait for the slower 7.2K drives. If you need the lowest positible latency then isolate those volumes to the 10K member.  I.e. for VDI, SQL, etc..  Then put the less intense IO volumes on the 7.2K member.

Understood. 

Equallogic will only create RAID based on ALL disks within that physical SAN (member). 

Each physical SAN (member) must contain the same type of drive (SAS or SATA) and can't be mixed.

Thanks for information. 

You are welcome.

Thanks. can close this post.
