Ontap SELECT SSD

BERNTSEN Basil

Hi folks,

 

I was told by someone on my account team that SSD isn't "allowed" on Ontap SELECT. That said, I found in TR 4517, page 9, (http://www.netapp.com/us/media/tr-4517.pdf) that in fact we can use SSDs. Anyone here know the whole story?

 

·         If I attach a bunch of SSDs to a RAID card and present them to an Ontap SELECT VM, can I use them?

·         Will it try to use them like spindles, without any of the new 9.0 flash optimizations?

 

Thanks!

RE: Ontap SELECT SSD

Tony Bar

Basil –

 

For ONTAP select all the storage must be of the same type and speed (e.g. 7200 RPM NL-SAS, 10000 RPM SAS, SSDs) so you can’t mix and match say 20x 4TB NL-SAS drives and 10x SSDs in the same ONTAP select VM.   I haven’t seen or heard about any restrictions on disk type though and the TR you linked definitely implies that they’re usable.  

 

As far as flash optimization goes, I am pretty sure that only applies to AFF filers and not ONTAP 9.0 in general so that would seem to rule out ONTAP Select.

 

Thanks!

RE: Ontap SELECT SSD

Parisi, Justin

No SSD support in ONTAP Select yet. That TR doesn’t explicitly say it’s supported; it just mentions that other solutions need SSD:

 

Although some software-defined solutions require the presence of an SSD to act as a higher speed writestaging device, ONTAP Select uses a hardware RAID controller to achieve both a write performance boost and the added benefit of protection against physical drive failures by moving RAID services to the hardware controller.

RE: Ontap SELECT SSD

BERNTSEN Basil

It does not say that SSD isn't supported, but I've heard that from multiple people: "All locally attached storage that is managed by ONTAP Select must be of like kind with respect to storage type and speed" is all we get in writing.

 

So if we only have SSDs on the servers, we can't get support for ontap select?
