Also,did LSI provide you guys with a list of tested SSDs? Their FAQ says to go to www.lsi.com/channel, but I can't seem to find it(though I didn't look too hard).
- MSI H81M-E33 V2 - Haswell Intel Pentium G3220+ 60GB Vertex 2 / 500 GB HDD/6GB/EVGA 9600GSO/ Windows 7 + VMs//Dell Latitude D410 -1.6ghz Pentium M, 120GB IDE HDD, 2 GB DDR ram.

Perhaps 48 or 32 is too many, but what about 8 SSDs to compare
the Enterprize $2170 1.8TB version with 8 240GB $480 OCZ Vertex
3 Series 240GB drives for about 2 times the cost?

The enterprise isn't running Vertex 3's in a data center, it just doesn't make sense for endurance reasons. You really want a drive tweaked for that use profile.

Do you think that it is appropriate to pair a 120GB OCZ Vertex 3 MAX IOPS with 3 x 1Tb SATA in RAID 5? The enterprise class drives are so expensive and the server will not be heavily loaded or dealing with a huge amount of data.
The SSDs that Dell can provide are hugely expensive and have poor performance. If I could get two years out of the SSD, I would be happy with that.

In our tests as you might be aware, we used a V3 MAX IOPS, since it was on the older 3x nm process, giving it a head start in write cycles versus the 25nm async/sync-equipped SSDs. Beyond that though we don't have any endurance figures we can help you out with. If price is not as big of a concern, you could always have two installed with the second SSD as a hot-spare.

I am going to do some performance testing soon, but have posted some pictures of the SSD installation into the Dell PowerEdge Server:

For cachecade, how to enabel 25 GB hot date zone. And how about your test sizing to fill in your hdds?
When we tested that function, we cannot get similar result. We used FIO (libaio engine, direct=1), result is very similar with pure HDDs (8* 10k hdds).
