HDS high-end as a VPLEX back-end

Hi Everybody!

I would like to ask if anybody dealt with HDS high-end as backend storage for VPLEX. I'm interested in selecting the proper host mode and options for VPLEX host group at the HDS array side.

I would like ask also about an article number 000185137. Unique Write Same primitive. I know that there is an ption on mid-range arrays that looks like a tick for enabling WriteSame. But what about high-end arrays? And maybe someone can tell how to disable this primitives in the storage view on VPLEX?

Hi Vsevolod,

I can't answer the high-end arrays question, but here are the commands to disable the various primitives for VAAI for a storage-view.

Note: I recommend not disabling these unless absolutely necessary.

VAAI primitives are a property of a storage-view.

Check the properties of each storage-view:

VPlexcli :/> ll /clusters/**/storage-views/*

Enable/disable primitives for all existing storage-views:

CAW/ATS: VPlexcli :/> set /clusters/**/storage-views/*::caw-enabled [true|false]

WriteSame: VPlexcli :/> set /clusters/**/storage-views/*::write-same-16-enabled [true|false]

Xcopy: VPlexcli :/> set /clusters/**/storage-views/*::xcopy-enabled [true|false]

Or modify a single storage-view (substitute "X" below for cluster-1 or cluster-2):

CAW/ATS: VPlexcli :/> set /clusters/cluster-X/exports/storage-views/mystorageview::caw-enabled [true|false]

WriteSame: VPlexcli :/> set /clusters/cluster-X/exports/storage-views/mystorageview::write-same-16-enabled [true|false]

Xcopy: VPlexcli :/> set /clusters/cluster-X/exports/storage-views/mystorageview::xcopy-enabled [true|false]

Enable/disable all new storage-views for the various primitives:

CAW/ATS: VPlexcli:/> set /clusters/*::default-caw-template [true|false]

WriteSame: VPlexcli:/> set /clusters/*::default-write-same-16-template [true|false]

Xcopy: VPlexcli:/> set /clusters/*::default-xcopy-template [true|false]

Regards,

Gary

Hi everybody!

I found a list of HMO in VPLEX ProcGen. Could be usefull for someone (see below the copy-paste out there).

The write same primitive is mentioned there only for Midrange HDS systems (AMS\HUS).

Hi everybody!

Anyway, KB000185137 looks strange on this question. I have consulted on HDS community and there's realy no HMOs which contol the WRITE_SAME primitives itself on high-end arrays.

Is there any way to check it with engineering if HDS high-end arrays are really affected by the issues with WRITE_SAME?
