While we have not purchased yet, let me tell you why we most likely will soon. Little background first.. We are a small hosting company that currently has five ESXi4 hosts with about 75+ VMs. Our primary storage is an outdated hybrid FC\SATA drive 2GB IBM DS4000 with several RAID5 LUNs (9TB provisioned and 6TB used). We decided to move from VMware given their insane (for an SMB anyway) licensing and maintenance costs. We are a Microsoft partner\reseller and qualify for SPLA licensing. Right there Hyper-V immediately grabbed our attention and we realized Microsoft had really raised the bar with Server 2012 on becoming a competitive hyperviser. So it's settled, we are now a Microsoft shop and we needed to hash out storage. We had been researching replacement options for awhile and everything had been hardware\appliance based i.e. Netapp, Aberdeen, XIO, IBM, etc. Nice to have things would of course be thin provisioning, de-dupe, replication, 10GbE. I just assumed I would not get those given the budget laid out.. i.e. a couple 10GbE switches alone would eat up most of our avail dollars.
I stumbled across StarWind and my first thought was you would have to be crazy to run a software SAN in production especially on top of Windows right? But wait, all our "nice to have things" were actually supported. Spent some time Googling the company and products and everything I came across was positive. Ok, I am still not sold yet though.
Then I got to thinking about how inefficient we are at the local storage level. For example, each of our physical servers has a 2TB RAID5.. FOR A 6GB ESXi4 INSTALL!! We are wasting 97% of storage we have already invested in. In fact, we have more unused local storage than the entire size of our FC SAN. WUT?? Talk about under utilization and server sprawl. Even after adding new drives to each server to get the usable space we need (and redoing the RAID levels) we still have several avail drive bays for future growth. <borat> VERY NICE!! </borat>
I dug a little deeper, spent some time in the resources area watching videos, reading manuals, whitepapers and came to the conclusion that not only does this sound great on paper it seems to actually work given everything I have read. Ok, let me contact sales and just get a feel for pre-sales tech support and customer service. This is where I was really impressed. The promptness and knowledge of my sales person and the technical resource was superb. They took the time to actually understand my environment and make recommendations unique to me; not vague generalizations that may or may not apply. My plan today is to better utilize the hardware we have with StarWind all while being substantially under our CapEx.
Now, with all that said, I do wish the Native SAN for Hyper-V supported more than three nodes. I would rather go that route and use RAID0; however, doing so would only leave me two servers for my Hyper-V cluster which would not be sufficient for our number of guests.
Regardless, I am excited to be implementing the product and am looking forward to the project!
