SSD as Cache in DSS V7

[m.casco]

My problem is that, with my hardware, i´m having poor speed/high latency.
I have thought that OPEN-E DSS V7 may use a SSD as cache like vSAN does.

Here we have tried Starwind software V6 and it works great, it uses system RAM as cache.
Then i thought that FILE I/O in DSS V7 will work the same (this is because we saw that With Block I/O the ram usage is low).
I have setup FILE I/O Write-Back for testing and I have found this surpprise:


Since when i cannot use FILE I/O in cluster mode?

Thanks!

Yes, with File I/O we dont use this for the Failover - stated on page 52 of the manual. Now beginning of next month we will be launching a new product that will be based on ZFS that you WILL be able to use the SSD drives for caching

We will be providing more information on this new product on our website with the other functions like Compression, Thin Provisioning and De-duplication and more...

Great news!!
It will be available as a free update?

There is no upgrade from the DSS versions to this new product as this a different product and is using ZFS which the DSS are not based on ZFS.

So, we have to buy this new software because our license is only for DSS?

As of now yes because these are 2 different products and feature sets also you may not have the proper hardware. We will be looking into this to see what types of upgrades we might be able to offer but as of now there is none.
