Hi,
we are currently looking at an expansion of our current storage. We are running a 3 node ESXi cluster (not yet on vSphere 6.0 but planned to be) - with roughly 600GB of RAM on 72 Cores. We are planning on deploying ~200 VMs there. Mostly Windows (2008R2, 2012R2) ones.
The key space saver would be deduplication for us. We have a 3 node Hyper-V cluster as well and Windows Storage Space's deduplication brings us roughly 1:20 space saving(!). So we can say, we have lots of identical data - no surprise since our main use case is to clone a template, do some small modifications and leave it running until we can dispose it.
Thats why I think can Tegile be a good fit for us. Their deduplication looks good on paper and a few tests in their lab also showed good space savings while maintaining good performance during the clone operation.
Key question is: Tegile is based on ZFS (forked around 2009) - so what is the difference between ZFS and Tegile? How do they handle the performance degration when the storage fills up? What about the performance penality with dedup? (It seems to be heavy on ZFS)
Anything else to add?
Cheers, Tom
