As hinted at in another thread, above starts what will be an update to my current main data store. This will replace a HP Microserver Gen8 which gave me a scare recently when a disk fell out of array, and I decided I really should have double redundancy. It also gives me an excuse to add more capacity.
I like the idea of server hardware (primarily ECC ram) and wanted more of the same, and the HPE ML10 Gen9 seemed to be a good low cost donor. The case it comes in is too limiting, so I was going to relocate it into the Define R5.
I've done some sanity tests on the ML10 Gen9 to make sure I can run it, since servers can have funny behaviours we're not used to with consumer kit. In short, it takes a standard PSU so I can replace it with something nicer and more SATA connectors. The mobo front panel and USB connectors are 2mm pitch, instead of the more common 2.54mm (0.1") pitch so I'll have to make some kind of adapter for that. I've done a proof of concept for the power switch only for now.
The mobo only has 6 SATA ports on it, and I've got a PCIe 2 port card which I checked works to give me the up to 8 drives I will start with. I haven't 100% decided yet, but initially I'll go unraid with 4x3TB storage, 2x3TB parity, and 2xTBD for redundant cache. I'll reuse existing drives.
One quirk of the server mobo is it will refuse to boot unless it has a system fan connected to it. I will need one anyway, but it was a pain when testing after extracting the mobo from case.
The performance of the system is nothing exciting, but it doesn't need to be for my uses. I did find it amusing, running off a 150W PicoPSU it was only pulling 8W measured at the wall when sat idle at Windows desktop.
The mobo only has two DP connectors on it which slowed me down, until I realised an old monitor had a DP connection where my newer cheaper ones don't. However I couldn't find a cable other than the one on my desktop so I had to steal that. The desktop will make do with HDMI and dropping to 50Hz refresh until I get a replacement.
Job for weekend will be to start mounting the mobo into the case and initially steal something bigger than the PicoPSU from an existing system for testing. I think I have enough SATA data cables, but might need SATA power splitters depending on the PSU. Given it is a window case, I might still bling it up internally.
On that note, I could fit my spare 280mm AIO in the case, but that would make overkill sound like an understatement. With the included cooler the CPU never gets about 40C anyway. I also have a spare 120mm AIO but it doesn't make it any less overkill. I might go instead for a tower air cooler of some sort, depending on what I have spare. Most likely a Hyper 212.
