  1. he said the packaging indicated "100" drives, aka helium filled. they're actually "101" air drives. that to me, is not as described.
  2. also sounds disturbingly like a software RAID4 type implementation. SSD cache drive is far faster, cheaper, already implemented, and reliable.
  3. you bought 'em from amazon. stick 'em back in their cases, box 'em back up, and return them "Item not as described."

    Surges can be a funny thing. I had a client where we installed multiple $500+ Cisco access points, and this one specific AP location would get it's lunch eaten if there was a strong enough lightning storm nearby. Was a really fun day when it backfed into the $1000+ Cisco PoE switch that was powering EVERYTHING, nuking half the switch. Owner got tired of replacing expensive APs, so I started putting in "cheap" $100 UniFi APs... and they never blew up once.

    MY UPSes don't talk directly to unRAID... yet My Windows Server host does however, and if the power is out for a pre-determined period of time, it commands the unRAID box (and a couple others) to shut down, so as to preserve run-time for the more critical equipment. Since I now have 3 UPSes in the rack, I might let the unRAID one talk directly to it's "primary" UPS.
  6. so... you want unRAID to basically run the array as a RAID4 setup?

    Lifetime of UPS.

    I've been a long term user of APC SmartUPS units, all the way back to the mid 90s. Heck I just "retired" a pair of units that have 1998 date codes on them; the electronics in them finally has worn out enough that they no longer accurately report battery life and power utilization figures. If you didn't mind them flashing and beeping for 90 minutes, they'd still power the load for that long. I did, since they talk to servers and tell them when to shut down. The number of batteries i've gone through on them is probably an impressive figure. Like many other things in this world, your cost of "consumables" (batteries) will far outstrip the cost of a good quality device, in the long term.
  8. as a matter of fact, you do not. the front cages are expanders already, and have port provisions for connecting the 2 rear bays.
  9. Instead of extra parity, I'd rather see multi-array support and/or Gluster-like functionality. And after having done some reading on what Gluster does, I think I'd prefer that over multi-array. Less chance of crashing everything at once if something dumb happens.
  10. Posting this here, as it's one of the first threads that comes up talking about a P410 controller, and it could be useful to other people in the future. Setup: HP P420 (possibly P402 and any P-series as well) controller, in JBOD/IT mode. Attaching multiple copies of the same model hard drive (in my case Samsung 256GB SATA SSD drives.) Problem: Only one, possibly none, if the drives, become visible to unRAID. syslog contains entries such as: Oct 29 13:27:12 Cube emhttpd: device /dev/sdh problem getting id Oct 29 13:27:12 Cube emhttpd: device /dev/sdi problem getting id discovered: in folder: /dev/disk/by-id the following is found: lrwxrwxrwx 1 root root 9 Oct 29 13:27 wwn-0x5002538500000000 -> ../../sdh lrwxrwxrwx 1 root root 9 Oct 29 13:27 wwn-0x5002538500000000 -> ../../sdi Because of some interaction between the P-series controller and certain drives , while running in JBOD/IT mode it sometimes will not allow unRAID to generate a unique device ID, and can create the same ID to multiple disks. I am unaware of any "fix" for the controller that will correct this. My solution, swap out the P420 for an H240 controller and put it in JBOD/IT mode.

I don't know about the rules for shipping to europe though.
  12. 10TB are LFF. I know of no one making a 10TB SFF. When I bought the server it came with 14 sleds, as it already had the rear expansion bays installed.
  13. are there any suggestions for cheap GPUs that would benefit Shinobi and would work with unRAID? and how do I determine if such an addition is of value?
  14. I have WD white label 10TB drives connected to mine. They worked on the P420i controller as well, in JBOD mode, but there's drive ID issues with some manufacturers (namely, Samsung, in my experience.) @Newtious it's 12 LFF up or 25 SFF front, and 2 LFF or 2 SFF in the back (optional.)
  15. Going to bump this, not because I'm interested (yet), but find it interesting. I could see a case where you have an unRAID server (big slow) and a more traditional raid server (smaller, fast) teamed together and data gets "aged" between them, transparently to the user.
