I have a couple of questions on Storage Spaces and was wondering if anyone can provide me with some guidance. The scenario is as follows:
A single server Windows Server 2012 R2 Essentials, would like to create a Storage Space containing a single virtual disk to include all available space, and want to use 2-way mirroring, starting with only two
1-TB HDD, a storage space which I believe would consist of 2 columns. The questions:
1) Can I later expand this same Storage Space by adding, as needed, additional pairs ofmatched HDD, say, two 2-TB drives, first, perhaps later another 2 HDD, this time 4-TB each, etc., etc.?
2) If the above is possible, and would like the best possible performance, would it make a difference if I select thin or fixed provisioning? For that matter, can a fixed provisioned Storage Pool be expanded at all?
3) Lastly, in the above scenario, I would like, if possible, to include SSD tiering.
a) In this scenario, are two SSD necessary?
b) Is the size of the SSD tier dictated by the size of the HDD tier? If so, how is this size calculated?
c) If the size of the SSD tier is indeed dictated by the size of the HDD tier, would I then have to resize the SSD tier as I incrementally grow the size of the HDD tier by adding matched HDD pairs?
Thanks for any help you may provide.
