So the time has come, my Company is looking to purchase new hardware.
Ive sort of settled on continuing with VMware for the next few years, and slowly moving stuff to either Azure or vcloud. but for now i need hardware. Servers are pretty much settled, in that im looking to switch from Opteron based Dell machines to an Intel platform on the 2697 v2 CPUs with plenty'o'RAM somewhere btween 384 and 768GB, The vendor is not set in stone, but the Vendor is prety much going to be the one, who can deliver me some nice storage.
Our storage today is comprised of Dell Equallogic. It has served us well, its easy to manage. With that said, we have moved to a more write intensive enviroment (85% of our IO is writes), and the tiering in Equallogic solution is close to horrible, especially if you have more arrays than you can fit into a single pool.
We are looking at around 48 TB of effective capacity needs over the next few years. its an rough estimate, cause who the hell knows what the company is planning to do.. i sure don't. and i doubt the management does either. i need to scale accordingly. and today we use around 26TB.
Our enviroment is 99.5% VMware based, with a few standalone oracle servers. They come in a total hefty 1TB of storage need.
We prefer having an enviroment that is situated in one storage system, but its not 100% needed. Our Standalone oracle installation can run on some local storage (maybe some SSDs for performance), and we'll be just fine.
With that in mind, im looking at the following Vendors:
1) HP 3Par 7400. Ive read up on it, and it looks like its pretty much the smartest allround solution i can get for my money. i like the idea of micro-raids and the full efficiency of disks it provide. it also seems to provide some SSD caching on writes, which i think is important
2) Dell Compellent. A clear contender, it does stuff a bit different than the 3par. but it has the dataprogression i think we need.
3) Oracle ZFS Storage Appliance. My Boss wants me to look at what oracle can deliver.. from what i can read out of specs and datasheets it provides lots of oomph, and gives several advantages with regards to Databases. But it lacks basic VMware functionalitets like VAAI.
4) Going Hyper-V Storage Spaces route.. Maybe its the way to go and switch out good 'ol VMware and go with Storage Spaces cluster. Main issue is a severe lack of Certified JBOD chassis for the sucker
5) VMware VSAN. I totally dig what VMware is doing. Its smart, scalable, Secure and hopefully fast. But its awefully new, still in beta.
It does provide me with an opportunity to save a bunch of money on storage though, and we can provide our oracle/linux machines with local storage instead, or Create a VM with NFS system for drives.
Switching im thinking also 10/40Gbe switching for storage, and for Vmware/Hyper-v maybe even considering Infiniband.
Anyhow.. any input would be appreciated.
