StarWind Software

Hi,

I am looking at starwind to see if I can use this for accelerating my existing SAN (IBM DS3524 with SAS connection).

I have a separate two node cluster for storage (ScaleOut FS) which is working fine, but not so great write speed. So I have added some SSD to each node in the cluster which I want to use for L2 caching.

Has anyone tried this or is there some documentation describing what I am trying to do?

The Things that I don't know are:

* Can i use Starwind as an "Accelerating gateway" in front of my SAN?
* How should I create the L2 cache (one on each node or should it be a "Starwind mirrored device")?
* LSFS or raw devices (What are the risks/benefits of LSFS)?

Best regards

Hello,

L2 cache align only read operations, so if you have more than 80% read operations in you production, go ahead with L2 cache.

Before you will implement LSFS, you should read LSFS technical documentation:

I would recommend you to use flat devices(image file) with L1 cache. Recommended size of cache(Write-Back) should be 1GB L1 cache per 1TB of storage.

Thank you.

Thank you for your quick reply.

Will the L1 cache do writecaching on hyper-v workloads?

Hello,

Yes, L1 cache boost up read and write operations, so it should suit you perfectly.

Thank you.
