Nah. They're old servers, only 3Gbps SATA and PCI-x, we use multiple 1GigE cards, some with bonding. If the SSD caches don't add anything significant, we'll upgrade the motherboards and controllers. The chassis is still perfect.
I have not seen clear cases for SSD cache in Linux. There are two or three alternatives, and at least one of them has been abandoned. Others are too complicated. I considered using an SSD as cache on my desktop, but had to abandon the idea.
If you get something conclusive I'd be interested to know, although your use case is very different from mine.
If you're using linux md-raid, then SSD journal support is being added. This appears to have quite an impact. Mostly write speed, of course.
That is great news regardless and I've never thought about the benefits of that before. As to the storage server, I don't know yet if it will be a build-from-scratch unit like Per described, or a used NetApp filer. I haven't started to price used NetApps yet.
