Help with Servers

[RCG]

I am interested in playing with starlings virtual San free edition and would like advice on 2 node server set-up.

I am thinking each node will have 4x4tb in raid 10 for storage and 2x 800GB SSD in raid 0 for server side l2 cache. Raid 0 sata for boot

I will be using 16VM's totalling 68GB of memory per Host so if I have a host failure I need to run 32VM's and 136GB of Ram plus host and solaewinds virtual San l1 cache

With that in mind I was thinking of 128 + 32GB of memory per Host, so 160GB of memory. 2x 10GB and 2x 1g networking per server.

With this set-up would I be able to do 2 node hyperv cluster with l1 and l2 cache with dedup inline?

Hello RCG,
Thank you for your interest in StarWind VSAN.
Currently, StarWind VSAN Free cannot be installed on the host where Hyper-V role installed.
So, you need NFR (https://www.starwindsoftware.com/starwi ... ense-users) or trial license key which will allow you to build the cluster and run VM on it.
Regarding your question: since you mentioned inline deduplication, it looks like you are going to use LFSS devices. According to LSFS Technical description https://knowledgebase.starwindsoftware. ... scription/, it requires 7.6 GB of RAM per 1 TB initial LSFS size with deduplication enabled (it is not related to L1 cache).
So, assuming that you will have about 12 GB of RAM free (do not forget about OS (~4 GB) and L1 cache (~8 GB)) it will be enough for 1.5 TB LSFS device.
