That is why we decided to keep it simple with the setup. so in the end we doubt that it is any cheaper and that it safes us any time at all. On top of that we need to certify the system in some way, I am no expert in this but after I read a few things about it I just stopped.

If we go virtual we would need a complete mirror of all our running in VMs, so another server, the DB needs to be synchronized, which needs an extra license from the software vendor and monthly service contract goes up.this already is a rats tail. If the image server fails we also can continue to work via a fallback routine. Using physical server one of the 3 servers has a fallback option for one software component, so we could still continue to work. if the virtualization server is down we can't work AT ALL. If we virtualize they bill us per hour for a bug which is not reproducible anywhere else The second company is new, I haven't asked them yet - but i pretty much know the answer.
Seen to many strange bugs not reproducable in direct hardware setups, performance issues - one the most common being performance issues even though load on host and guest is low " - so there is that. One of the two companies says directly: "you are free tor virtualize, but we advice against it. We have 2 other systems, but they are not as vital so we are not talking about those. We rely on 2 software components needing 3 servers, one of them is storing images (1 server). This is getting waayyy off topic, but well here we go: How many discs should the array not exceed (including parity discs) And if so are write less intensive disks OK for it. Is a RAID 6 with 36 to 40TB a viable and safe option to go? Or is RAID 10 the only answer? (yes we make backups, but with millions of files you can't make one everyday) However purchasing SSDs for a RAID 10 is well.pretty expensive.Īfter digging into RAID 5/6 I read that SSD don't suffer from the UREs the way that HDDs do and that makes a rebuild on a RAID 6 pretty safe. Since its really slow we thought SSDs might help a little here. Problem: reading the small files randomly is painfully slow with average of 15-20MB/s. Writes per day on the array is about 170-200GB Maximum files size is somewhere around 14MB, accounting for 0,x% of all files. Millions of small files with average between 200 and 300kb.

We will get a new server soon and so it again time to ask ourselves how to store the data.
