  1. 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?
  2. 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.
  3. It was using that. Setup itself wasn't too long so for all practical reasons it's pretty close to turn key.
  4. Stick with the brands that have their own fabs. Samsung, Crucial/Micron, Toshiba/OCZ.
  5. 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.
  6. 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
  7. 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.
  8. Given this is based around Windows software RAID, have you tried loading the disks into a JBOD (4 at a time), connecting them to a dedicated Windows Server 2008 R2 or S2012 R2 platform and importing the RAID groups? It would also be wise to contact a data recovery company, since there may be an easy solution to recovering the data through a RAID group import in a secondary system.
  9. Intel SATA chipsets generally perform much better in single drive situations than the LSI HBAs. Those numbers you are seeing look pretty normal. You'll notice more with higher loads or additional drives.
  10. LSI 9200 and 9300 series I'd say are more common than dirt. Most haven't changed dramatically over the years either. Getting those versus Adaptec will basically cover the majority of the market.
  11. The HK4R isn't SAS and the price you have is way off. CDW retail is 1294 https://www.cdw.com/shop/products/Toshiba-HK4R-Series-THNSN81Q92CSE-solid-state-drive-1920-GB-SATA-6Gb/4421240.aspx Volume pricing I'm sure is much better.
  12. Data corruption can be a tricky one to pin down. Bad cables, bad drives... consumer devices don't have the best error correction capabilities. See if the EVO stays clean.
  13. If you reboot node B does it move back to A? In windows there was also an area to manually move it back and forth.
  14. That is correct and why we reported the 4 individual VM values in the charts. The MySQL databases only need ~300GB each, the SQL server stuff needs about 700GB each.
  15. Are you seeing any errors on the NAS itself? What is cataloging the files and what are you using to watch them? That end might be corrupted.
