Server with SSD's

We need to replace our 10 year old HP server. We are currently looking into the option of using SSD's. We run everything in VMWare Esxi and have the following virtual machines:

- DC server 2012R2
- File/IIS/DNS/Print/Exchange server 2012R2
- 1 SQL server 2008R2
- 2 linux CentOS servers
- 3x Windows 7
- 1x Windows 10

We have about 15 users on the server. We think putting everything on SSD's would be overkill. We are wondering if using SSD's for caching is an option (like snapshots for backups).

I personally would not bother with SSD's for this setup.

I would probably look at putting a SAN in place, if you can afford to put 2 X 3PAR 7200's with normal drives in place.
1 in your main site and the other in your DR site, even you can buy one now and one later and sync them up then.
Then buy VMware SRM and you can have a scripted site failover done automatically in VMware in a number of minutes.

I would pay more attention to not using local arrays for VMware which is what it sounds like you are doing.
Also using two hosts instead of one in either site.
Would also look at sharing some of the load away from this server sounds like it is doing far too much "- File/IIS/DNS/Print/Exchange server 2012R2" If you have Exchange on premise which I actually prefer over 365 I would have it on a single server.

You can use SSDs for caching, there are two functions with ESXi which can leverage SSDs for caching.

Host Cache and vFLash Cache.

Most modern RAID controllers can also use SSDs as read cache although that may be a licensed feature.
