Edvard_Grieg Posted November 11, 2015 Share Posted November 11, 2015 Hi, I'm a fairly long-time user of Unraid going from a Celeron D system with a couple gigs of RAM to now and I'm now looking to shift gears again. A couple years ago I bought a used Dell T7400, it's outfitted with: 2xXeon x5482 32GB RAM Array 5xToshiba 4GB NAS Drives 1xWD 4GB Red Drive 1xSeagate 3GB NAS Drive Parity 1xSeagate 4GB NAS Cache Samsung 850 PRO 256GB - there is a symbolic link on cache drive to the separate BRFS array Other 2x Samsung 840 EVO 120GB in BTRFS RAID 1 Array - these have all docker installs and configs on them My current uses include Sonarr, NZBGet, CouchPotato and Plex. The docker plugins have specific core assignments and memory allocations Future uses include the above plus VMs (not sure on hypervisor yet) One of the 'tweaks' I made is with the 2xEVO SSDs...I found that when pulling down large amounts of NZBs and trying to unpack them it could tank the SSDs resulting in choppy streaming or deadlocks with downloading. To remedy this I effectively created a second cache array with the 2xEVOs and mount with the SNAP plugin. Since Unraid forces docker to be installed on the cache drive with btrfs, I created a symbolic link to the EVO array which appears to 'work'. The major caveat is that when the system is fully restarted, there is a bit of manual tweaking to get the right shares visible, and almost invariably I lose my docker configurations (have to rebuild/link the main download)...If there is a better way to approach this piece then please tell me!! For my future build my main objectives are: * Lower Noise * Lower Power Usage * Fewer Drives I'm looking at the Seagate 8TB Archive drives to replace my current array drives...looking at probably 4 in the main array + 1 for parity. I'm additionally looking at moving to new CPU/Motherboard etc so I can downsize to a smaller case (T7400 is full tower and stupidly heavy, hot, and noisy). I'm currently looking at: Budget varies, I'll probably do this in steps of a few hundred at a time 2xE5-2620 64GB RAM Supermicro MB 1xSeagate 8TB Archive for Parity 4xSeagate 8TB Archive for main array Cache Drives??? Reuse the 850 Pro and 840 EVOs?? PSU?? One of the 5 in 3 adapters for the drives A mid-tower case to hold it all Thank you for reading through this- let me know your thoughts on: How much of an improvement will I see in the areas of Performance, Power Consumption and Noise/Heat? Is there something else I can/should do for the secondary cache setup? What else should I consider or be thinking about? How will stability compare to my current setup (uptime of 82 days, last downtime was due to upgrade to 6.0.1) Quote Link to comment
mrmarkfr Posted February 25, 2016 Share Posted February 25, 2016 Sort of off topic, but I thought the PERC 6/i card on the T7400 didn't support anything larger than 2.2Tb, how did you get by this limit? I don't see a SAS or SATA card listed in your hardware. Quote Link to comment
