Some older cards and software RAID setups aren't very flexible with the device paths and have trouble recovering from out of order physical devices. Modern RAID of any sort shouldn't care anymore though. I think I managed to somehow fry the M1115 card that I got because I flashed it, got it to show in ESXi for a few reboots, and now the heatsink isn't warm, there's no LED turning on, and it doesn't seem to do anything in my other machine. Otherwise, I'm hoping it's because the tape I put on a pin is a little off because this would be another piece of hardware killed by ESD and I'm getting really tired of throwing away hardware at random.

Isn't always true, but when it is true it just adds to frustration and anxiety, which is not what you want when doing disaster recovery. Especially if you are dealing with someone elses server and they didn't write this all down from the start.

I would have been fine with that if the vendor didn't advertise it as coming with them. If they don't come with the caddies, don't use multiple pictures of the server with the caddies installed for your product listing.

taqueso posted:^^ nice, that's like the cop not showing up to court when you contest a speeding ticket The thing is, eBay just asked for them to cut an RMA ticket for me, since the main problem was they kept sending me form emails to create a ticket on their RMA system, which didn't seem to work for the eBay order number that was provided. Every time I called in the same customer support agent came to the same conclusion and "escalated a ticket", which would just result in the same form email being sent to me asking to create a ticket using their RMA page. I would have been happy with a partial refund or, worst case, having to ship the thing back and getting a TS140 from another vendor, but I'm not complaining about how things turned out. The UPS I got was one of the pure sinewave Cyberpowers that Skandranon is talking about, and it seems to be working well enough. It was causing surges where I had initially plugged it in, but as it turns out the outlet I put the server on was on the same circuit as my TV and networking equipment in one room, and my desktop computer in another room. Right now I have it plugged in to the same wall outlet that my air conditioner is on, which I'm a bit worried about when the time comes to start using it, but I don't really have any other places I can put it right now.

Combat Pretzel posted:FYI, we had this topic in the Intel thread. An UPS with modified square waves may trip up PSUs with active PFC and trigger their over-current protection. The low load in NASes should probably not, but if you get a cheaper UPS and the thing doesn't work as expected, it's probably that. To add to this: It's not really a huge problem in 110V countries with good power supplies.

Most of this talk about UPS only really matter when the power goes out and it has to switch to providing power. If your power never actually goes out, it's just a very expensive surge protector. It also can condition the power coming in, within limits, so if you aren't getting a proper 110V, it will fix that. Though, if that's a chronic issue, might want to get that addressed, instead of relying on UPSs to fix that forever.

Anyone have experience with PowerEdge T110 II Tower Server? They popped up on Slickdeals for $279 with free shipping for a base unit. Specs Intel Xeon E3-1220v2 Quad Core CPU 4GB DDR3 500GB 7200RPM Hard Drive DVD Drive No Operating System No RAID but 4 SATA ports for HD's which should be fine for my intended setup.

Combat Pretzel posted:How so? 110V appliances have higher input currents than 230V ones. The problem with PFC and Square waves has to do with the cross voltage at the boost converter capacitor banks, usually these are specced for 400V to accomodate 230VAC, but square wave 230VAC UPSes will have cross voltages in excess of 400V. A 120VAC UPS will not have this issue because they have closer to 300V cross voltages (usually 168V and -168V are the voltages they use, unless they have more steps). There's a ton of discussion on the subject here: http://www.jonnyguru.com/forums/showthread.php?t=3964 and the general consensus is 120VAC is fine. e: I guess I should've said you're not tripping overcurrent but overvoltage protection. deimos fucked around with this message at 20:55 on Apr 15, 2015 |

I can't believe I am asking this but I just want to make sure that for HOME equipment, this'll work. If I buy some (name brand) RAID enclosure to attach to my PC (e: oh uh, almost certainly NAS, but I suppose this question could apply to just a USB attached enclosure), and I put let's just say 3x4TB and 1x2TB in, when I replace the 2TB, the size of the array will grow, right? Have actually never spent any time with consumer NASs. ![]() e2: Here's me embarrassing myself, here's how little I've thought about consumer NASs. I wouldn't even buy one would I, I'd just take an old computer and slap a million drives in it, right? Oy, can a guy do any reading before he posts around here?

Unless you do something really weird array-wise, having the 2tb drive mixed into a RAID5 or raidz1 array is actually going to cause you to have less usable space than the three 4tb drives would have otherwise.

MC Fruit Stripe posted:I can't believe I am asking this but I just want to make sure that for HOME equipment, this'll work. Disclaimer: I'm not 110% sure this is the case, but I'm pretty sure it is. With RAID 5, I believe you're locked into whatever size you initially start with forever. With RAIDZ, your array can expand, but will always only be as large as the smallest drive in the array. In your situation, if you were to configure those drives in RAIDZ, you would start with 6TB of usable space (smallest drive is 2TB x 4 total drives, minus 1 drive used for parity). If you then swapped out the 2TB drive for a 4 TB drive, your array should increase to 12TB usable space. If you were to configure those drives in RAIDZ2, you would start with 4TB of usable space (smallest drive is 2TB x 4 total drives, minus 2 drives used for parity). If you then swapped out the 2TB drive for a 4 TB drive, your array should increase to 8TB usable space. GreatGreen fucked around with this message at 15:00 on Apr 16, 2015 |

That's exactly what I expected, thank you ![]() That said, I'm kinda talking myself out of it. I don't know, my thing is, I have all the storage I need. I just want to stop losing data to hard drive failures. Have an external drive, it fails. Have another, it fails. So I want an enclosure. Except they're (comparatively) expensive and again, I have as much storage space as I want. I'm not sure my problem isn't solved with a simple external drive or two dedicated to backups. I mean, that's solving my problem with external drives by adding more external drives, but still, it'd be a lot easier to justify buying an enclosure and populating it, if I needed storage AND backups. I only need backups.

MC Fruit Stripe posted:That's exactly what I expected, thank you Perhaps you could just do a simple 2x4tb mirror (RAID1) inside your desktop? Windows 7&8 can do that easily, with no additional hardware. That gives you 1 drive redundancy, and that protects against any data loss between backups. Also, enclosure hard drives tend to be the lower quality ones, so you're setting yourself up for more drive failures. It is also very simple to recovery from, unlike RAID5/6.

I feel like my situation would have been much different if I wanted to add storage - if I was looking to add 8tb but also ensure that it was redundant, enclosure all the way. But in my spot, where if anything I have too much room, and just need to start backing things up, I'm just going to go with a simple external drive and call it a day. Anyway I just wanted to follow up and say thanks, all the advice was great of course (and it's hilarious given what I do for a living that I know nothing about the consumer NAS space), but I'm the goon in a well and a simple robocopy to an external drive probably takes care of me.

Thing is, I thought about my particular situation - I've got all the space I need. I'm not running out of room for years and years. So in my particular case, if I take all this empty space and move some files around - instead of 2 drives that are 35% full, make it 1 that is 70% and free one up. I worked it out and basically with nothing more than a $150 5tb external from Seagate, and some file movement, I can back up everything I'd ever possibly want backed up. Good luck and godspeed. May your drives live forever.

Looks like the older Seagate 3TB drives are garbage https://www.backblaze.com/blog/3tb-hard-drive-failure/ Beginning in January 2012, Backblaze deployed 4,829 Seagate 3TB hard drives, model ST3000DM001, into Backblaze Storage Pods. In our experience, 80% of the hard drives we deploy will function at least 4 years. As of March 31, 2015, just 10% of the Seagate 3TB drives deployed in 2012 are still in service. This is the story of the 4,345 Seagate 3TB drives that are no longer in service.
