Failure and dealing with warranty is a pain and losing all this time not being able to plot will cost you so much more in the end imo. I heard there are some good gen4 m2 Nvme drives out there with upto 3.6 TBW cheaper than Intel Enterprise but I’m not sure how accurate these numbers will be after 24/7 several months heavy usage. You sound like you know what you talking about maybe I should buy them instead of single 8TB. Just looked while I was writing this and found 2x 4TB p4500 Intel SSD for pretty much the same price. Only can find 8tb Enterprise SSD in stock right now anything smaller is backordered or double the price from scalpers Thanks Ianj ,really appreciate the input.įunny thing is the brand new 8tb intel p4510 is still cheaper than 2 x HP ioDrive 2410 used right now lol. My HP ioDrive II (old but solid) is 2.4TB and can sustain 10-11 plots in parallel - if you have 3 slots that will likely sustain a higher throughput than the single 8TB - at a fraction of the price and a similar or higher TBW.Īm not saying the HP ioDrive is better - but 3 of them is almost certainly better - if you have the slots - and the CPU I checked - its PCIe 3.1 x4, NVMe - 3000MB/sec peak but its still TLC so likely to cap at about 1-2GB/sec sustained - and its VERY VERY expensive
DELL PERC H200 DISK PASSTHROUGH TEMPERATURE PC
I don’t really have enclosures per se - i have 32 disks piled up with 8xSAS breakout (about £75) and 8x4xSATA power breakout (about £40-45) and a DESK … lol i’ll get some plywood to wrap them in over the weekend and i already have a half dozen fans for a DIY QUIET enclosure - the HP SAS expander is £40-50 and an SFF-8087 to external (in the expander) about £15 - I think some guy made a YT video where he 3D printed a case but used the same approach for the disks/connectivity - he doesnt mention power which is a notable issue - a PC PSU only supplies 15-20A on 5v - which is about 20 disk MAX - i am powering them all off a single 12v Server PSU with a few basic DC->DC converters to provide 12v/5v to power all the disks (3 enclosures, 96 disk - but all small) They support 6GB SAS which with a typical 4TB disk is about 160MB/sec - i don’t know the max capacity disk it will support though - all my drives are 4TB and lessĭon’t go for the H700 - it insists on RAID-0 setup for each drive as it doesn’t support passthru and you can’t hotswap - that is why it is half the price It “broke” last night/yesterday - i have a small (3TB) target directory/root drive which i network copy off - well it filled and screwed up Linux and Swar - lost half a days work - its back up now but behind on the last 2 daysĭell Perc H310 or H200 (same card, different connector orientation) - both can be run hardware RAID but even better in IT mode (no raid but faster and simpler as a JBOD HBA) It supports 2xSFF-8087 cables, each supporting 4xSAS drives (so 8 out of the box) but each SFF-8087 can also be used to connect to an HP SAS expander to break out to 32 drives - so one HBA in the PC can support 64 drives - powering them is the challenge
DELL PERC H200 DISK PASSTHROUGH TEMPERATURE UPGRADE
I have a T5610 with 2圎5-2650v2 with only 1xHP ioDrive SSD in it (and a pair of regular SATA SSD in RAID 0 but they are SO SLOW in comparison) - and 2圎5-2670v2 in my drawer - i could probably switch 1xSSD to the faster machine, upgrade to the E5-2670v2 and get 35-40 a day - but i’d have downtime doing it - also that machine has an HBA and 8 SAS drives in it (part of the farm) and the SSD take a slot each … it would probably be ok but not keen on upsetting something that workĢx 2.4TB SSD means 2 sets of 10 - ie up to 20 in parallel - a regular 2TB NVME would be capped at 8 in parallel
Which SSD ? I use 2xHP ioDrive II (2.4TB each) which are PCIe data centre grade - they are not technically as fast as an NVME (“only” 2GB/sec) but they can SUSTAIN a higher throughput and have a stupidly higher TBW of 34,000 (vs the best NVME around 3,000) The 2圎5-2670 has been set to allow 5 plots in Phase 1 and each SSD is separate so combined it will allow up to 10 in Phase 1 - it does get pretty bogged down - i could perhaps reduce that to 4 but hey - if it works, don’t break it
