I'm looking to replace an estate of aging servers and networked attached storage with a virtulised environment. I've been out to a number of suppliers and they have come back with several proposals and I've gone through them looking at the finer details and I've kind of come to a decision on which one I want. However I wanted to see what other, more knowledgeable, people make of the various solutions based on their experiences with the hardware etc.
The solution will include a second data centre based about 300 metres up the road from out main data centre and the two are currently connected via 1 Gb fibre, 10 Gb fibre may be possible in the near future. The second data centre will house a BC/DR set up so that we can continue operating with minimal downtime in the event of failure of the first site. I will have a isolated network that the iSCSI traffic will flow across that is separate from the normal LAN traffic. The total spend is £150K. I am looking at 2 hosts at each data centre, they will both handle between 10 and 15 VMs each. VMware as opposed to HyperV because of the better functionality. Total storage required will be around 8 TB
The proposed solutions:
1) 2x Dell Equallogic PS6110E. 1 based in each data centre, these will be part of the same SAN rather than active/passive etc. The hosts will be Dell R720 with 192 Gb memory (2 at each site with Intel E5-2680 chips etc)
2) NetApp FAS2240HA with dual controllers at site 1 with NetApp FAS2240 with single controller at site 2. Again 2x Dell R720 at both sites.
3) 4 x HP StoreVirtual 4530 - two at each site. These will act in Active/Passive mode as we've been told that we need a third site for the active/active role to work correctly. 4 x HP DL380 servers (similar spec to Dell).
4) 2 x EMC VNXe 5300 DPE - one at each site. Again same spec servers.
Some solutions have recommended VEEAM to supply replication and backup (eg the HP solution) and others using their own solutions or VMware (eg the Dell one).
I realise I have not included much information but I'm really after people's thoughts especially if they have used any of these systems for real and what they think of them. Have they wished they put something else in place, or perhaps are quite happy with their choice etc. I hope you can advise.
Ah, time for another cuppa.
