Sorry for bringing up this old thread but I'm looking into using the ssd cachecade and hard raid.

Do you think this could cope or would minecraft need 100% ssd. I'm not quite sure of hybrid cache performance, has anyone else tried?

Also with the ovh offer it says 2x300gb ssd. Does this mean in actual fact you get 600gb of ssd cache? Or is this in raid 1?

Just like if we all decided to download a Bluray Linux ISO all at the same time from our OVH servers! (chuckle)

I can imagine 64 servers causing a massive IO bottlneck though, yeah.
Though with at least half of these servers having 0 players the CPU can keep up fine. Not sure what would happen if all the servers were full as this has never happened, but probably a disaster.

Yes, that's fair enough. I don't think it made my question invalid though. I was under the impression that IO wasn't such a big deal with Minecraft servers any more. I've had 2-3 running at once on my old dedi (which was similar spec'd to the mSP) not using ram disk, not to mention various other game servers, without issues.

I'm not saying that my experience means that SSD/ram disk isn't needed - I was asking for clarification with regards to other people's experiences.

Mainly minecraft and source games yep.

That's what I thought, bit too I/O hungry.

Also is it worth possibly getting the SAS hybrid with SSD cache?

Hi,

I'm just wondering if anyone knows how much of an I/O boost the MG SSD has compared to an SSD cache?

I'm hosting lots of game servers, some of which are pretty I/O hungry.

I'm wondering whether it would be safe to switch to a HDD with an 80G SSD cache.

Does anyone have any experience or info about the hybrids?

Thanks!
Victor
