  1. Sounds almost like the drive failed. If you take it out of the group and plug it into something else does it report anything?
  2. 200TB SAN/NAS for feature film

    While ZFS might have some FS improvements some could argue, the dead simple file sharing capability and speed of SMB3 makes Windows the preferable option IMO.
  3. 200TB SAN/NAS for feature film

    To put a bit of perspective on the CPUs, I was able to hit ~2.1M IOPS at about 20GB/s (bandwidth wasn't the limiter, only IOPS) on two 2.9GHz CPUs with 8 cores each. With the HDD platform you are looking at, nearly entry CPUs would probably work, file serving at this scale is very lightweight. Leveraging SMB3 for your file transfer protocol would be optimal if each side is Windows-based. (Win8+ and Windows Server 2012+).
  4. 200TB SAN/NAS for feature film

    The newest processor lineup naming is still new for me, but if you shoot me a link to that page I'll give you a few options that make sense. Its really a clock speed times core count question.
  5. 200TB SAN/NAS for feature film

    On the chassis, that model should work, although there may be better options out there, I haven't looked at the models vs pricing in a while. Getting a full package with chassis + expander + motherboard + SAS card would be better knowing you get matched components. CPU load for HDD storage is pretty low, you could go for fairly low-mid range CPUs and get out just fine. Same with DRAM... 16-32GB would probably get the job done easily. On NICs, really depends on cost versus what you need. Are you going direct attached to bypass a switch? I'd probably look at the Intel X520 or X540 NICs which are pretty cheap, and get three dual-port cards. Use one in the server and the other two in the desktops, direct attach with static IPs. If you have budget for a switch in that mix go for a Netgear model. Do a 2 SSD combo (240 or 480GB light enterprise) for RAID1/mirror boot drives.
  6. 200TB SAN/NAS for feature film

    Windows Server and either hardware RAID or Storage Spaces would give you the sharing aspect you are after... at that point your bottleneck would be whatever network connection you planned on leveraging between the workstations and the server. I'd personally look at a Storage Server option from Supermicro... same basic chassis, but has the motherboard as well.
  7. Netgear ReadyNAS 4312X Review

    Nope, that IOPS figure is correct. For a pure HDD system, iSCSI 4k random is pretty tough.
  8. VMware VSAN 6.2 All-Flash Review Discussion

    Our disk group number was governed by the number of cache SSDs we had. We needed an even split, so that's how we ended up in 4 groups of 4+1. Building a setup from scratch you'd probably want to leverage something that makes more sense from a cost perspective, since as we saw the SSDs didn't have a limit on the performance of VSAN, it was more that we hit the top end numbers in general for the platform at the time we reviewed it.
  9. What resolution are you testing with? I think depending on the startup settings it tests at the 1920x180 resolution or in 4K... maybe your numbers are at 4K?
  10. Minimal, I'm not sure it consumed more than a couple hundred MHz during the time we had it going in the background. We've been working with the Nexenta team over the duration of that review and they are still working on it internally. Should hopefully find out more soon on that topic.
  11. It was using that. Setup itself wasn't too long so for all practical reasons it's pretty close to turn key.
  12. Crucial M500 alternative

    Stick with the brands that have their own fabs. Samsung, Crucial/Micron, Toshiba/OCZ.
  13. HPE MSA 2042 vs NetApp E-2724

    We're leveraging the FC side with a Brocade 6510. So far performance has been fantastic, outpacing some other all-flash units in fact. Very fun platform.
  14. Launched back in early 2015, the Intel DC S3610 Series is a line of SATA 6Gb/s SSDs intended for applications such as virtualization and e-commerce. These SSDs are equipped with 20nm Intel NAND Flash Memory technology designed and offer a blend of endurance and performance. Intel quotes the DC S3610 with sequential read and write speeds up to 550MB/s and 520 MB/s, and random 4k speeds up to 84,000 OPS and 28,000 IOPS for reads and writes, respectively. Intel also claims a Quality of Service of 500 μs for random 4KB reads measured at a queue depth of 1. Intel SSD DC S3610 Series Review
  15. NVIDIA Quadro P2000 Review

    Pass through I don't know, but noise level was silent. You could tell it was on because the fan blades were moving, but even with the cover to the desktop off you couldn't hear it.
