tldr: What is going on with these benchmarks, and do I really need a P3700 to get decent performance for VM's hosted on SSD ZFS pools? Ceph: how to test if your SSD is suitable as a journal device? | Sébastien Han So I have a proxmox host that currently has the following configuration: 2x240GB...

Hi All, Running ZoL v0.6.5.3 on debian jessie. I just created a new pool consisting of 12x 4TB drives in raidz2 (everything on this pool is backed up, and maximum reasonably safe capacity is more important). I just nuked my previous pool of 2x6 drive raidz2's for this configuration to gain...

Hi Everyone, I'm trying to find a wireless solution for my house that actually works. To get proper 5GHz coverage for most of the house and front/back yards I need 4+ AP's and have been using unifi UAP-AC's since their release a while ago. I can't say i've been very happy with them (middling...

Hi everyone, I'm trying to figure out a way to measure the queue depth of various windows applications i use to better understand if they will benefit from upgrading to something like the intel 750 ssd. The only application i've been able to find (but not download) is intel IPEAK. It seems...

Hello everyone, I'm running ZoL on a ubuntu 14.04 kvm guest with m1015's being passed through to the vm. Performance has been great. The problem i'm trying to solve now is NFS performance between the storage VM and additional VM's on the same host. Iperf tests between the storage and guest...

Hi Everyone, I've been running ZoL for years now without any trouble...until now. zpool status -v pool: tank state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the...

Hi All, I'm in the middle of upgrading my home nas, specs are: CPU: 2x Xeon E5530 RAM: 48GB ECC Mobo: X8DTL-iF HD: 12x 4TB Hitachi Deskstar (2x6 drive raidz2) HBA: 2x M1015 IT Mode esxi raid controller: LSI 9260-4i SSD: 2x sandisk extreme II 240GB Raid1 esxi: 5.5 Running the...

I'm in the middle of upgrading my zfs all in one server to 4TB disks and new ssd's. I'm looking to replace the br10i i currently use as a raid1 datastore in esxi with something faster to accommodate the new ssd's I am going to be installing. I've read the write performance on IR flashed M1015's...

The last time I attempted an upgrade to esxi 5.5 ich10 passthrough was broken (when it was released). I haven't tried recently, has anyone had any success?

I'm looking to upgrade an old 2U I currently have 12x 2TB drives in raidz2 (2x E5530 xeons, M1015's flashed to IT mode, 32GB ECC ram). This is used primarily for bulk data storage and a few VM's. This is a personal server not anything in production or anything. I currently have an AIO setup with...

Sorry if this is the wrong sub to post this in, I really wasn't sure where it belongs. I'm looking for a cloud storage provider to mirror my front door security camera footage to (it can be self hosted too, the app is all that matters). My biggest requirement being that they have an...

I picked up an asrock E3C204-4L a few days ago (my first non-supermicro board in a long time). I was curious how the asrock would compare and it had better spec's than the supermicro for less money. I cannot figure out how to configure SMTP on this thing. I'm not even sure if it supports...

I currently have a 12x2TB drive raidz2 pool that is nearly full. I'm looking into rebuilding with 11-12x4TB drives. I'm not sure what the best compromise would be between speed and reliability. Should I run: 2x6 drive raidz2 arrays 1x11 drive raidz3 (have to drop 1 drive for raidz3 for...

I'm looking into replacing an aging supermicro X8dtl-i motherboard with something socket 1155. I have an e3-1230v2 lying around with some ram and am looking for something with IPMI. I've had many supermicro boards over the years and they've mostly been fine, however i'm reading the X9SCA-F may...

Hello everyone, I'm trying to find an affordable (used is fine) serial console server that has dial in support. I have some equipment in a remote location that i need to access in the event of an internet outage, and using a 4g modem for fail over is too costly. I've come across several...

I'm looking to replace my logitech G710+ with an equivalent from another manufacturer. I like everything about it but the lack of linux support (it blasts 6666 to console). Logitech supports response to this is to not buy logitech products, so that is what I intend to do. Does anyone know of any...

I've been running zfs on linux for some time across various types of hardware with great success. I recently upgraded my home NAS with 6x 4TB hitachi coolspin drives in raidz2 configuration running ubuntu 12.04 with zfsonlinux. I was previously using 1TB drives in a raidz2 on the same hardware...

I'm curious if anyone has any experience with these drives? I've had great luck with hitachi in the past and these seem to be the cheapest 4TB drives around right now. I'm planning to use them in a raidz2 array for storing media, so they don't need to be particularly fast, just enough to...

I'm looking to add some additional hot swap bays to my supermicro SC743T-665B case. I'm running zfs on linux utilizing the oboard sata ports of a supermicro x8dtl motherboard + m1015. I found this cage on newegg but i'm not sure if it could cause any problems i'm not aware of? I'm looking for...

I've had nothing but problems with the nvidia drivers on my last 3 machines. From the GTX 680 to my current SLI GTX 780's. My current setup requires a reboot at least every 1.5-2 days otherwise after launching any game the whole machine will freeze for ~10 seconds non-stop in 30 second or so...

I've been confused about upgrading esxi for some time now. I understand how to apply updates, but what i'm not sure about is if any updates can be skipped? I'm quite far behind now on updates and it will take hours to install them one by one, rebooting after each is applied. Can i skip all of...

I've googled for a while but i'm coming up short. This seems to be possible with the apple 27" thunderbolt displays, but i would much prefer if some type of adapter exists that will convert a single thunderbolt/displayport output on a new macbook air to drive 2x 2560x1440 displays (dual-link dvi...

I have no experience with picopsu's but was considering building a few pc's with this one: http://www.quietpc.com/st-nano150 Are they generally reliable? I'm building a fanless system with ssd's attempting to make them as reliable as possible and i just wanted to make sure the PSU isn't going...

I've been trying to find a solution for network adblocking but i've come up short after a lot of googling. At first it would seem that privoxy or squidguard are the way to go, but i've been unable to find any reliable way of converting adblock plus lists (easylist, fanboy's list) to either of...

I'm able to pick up an NEC LCD3090WQXI-BK used for ~$780 local, i currently have an HP ZR30w, Dell 3007WFP, and apple cinema 30". This monitor is going to replace the apple as i need VESA mounts. Assuming all goes well and it is in good shape is this worthwhile, or should i just stick with...

I'm curious what everyone's experience has been with aluminum mouse pads? I picked up a mionix ensis 320 (black) a few days ago and while i like it 2 days in there's already a small silver chip in it. I was concerned about how resilient it would be before i bought it but oh well. Has anyone else...

I don't usually post product reviews of any kind, especially negative reviews but my experience with razer as a company lately has driven me to this. I picked up a razer ouroboros from best buy yesterday after anxiously awaiting it's release for months only to get home and instantly experience...

Hi everyone, *edit* So after thinking it over a bit more, i'm thinking it's probably best to replace the 2970G and the dell. I'm leaning towards a cisco 3750g-24t-s as the 2970G replacement, and something cheap and fanless to replace the dell. The dell has to go because it is having issues and...

Hello everyone, I have esxi 5 running on my supermicro X8DTL, which unfortunately does not have IPMI. Under health status in the vsphere client none of the hardware health is listed (fans, voltages, etc). Is there any hope of getting some basic hardware monitoring to send email alerts of fan...

Hello everyone, I'm currently driving 2x 30" monitors with my GTX 480 and the 3rd with a GT 520. I only game on the center 30" monitor, the others are strictly for desktop apps. When upgrading to a new GTX 680 i understand that the 4GB cards have negligible performance advantages for a single...

Hello everyone, Sorry if this is a dumb question but i've googled every way i can think of asking without any results. Is there a way to view how long it has been since my laptop has been attached to an AC adapter in os x? Also, on a slightly related note, is there anything similar to...

Hello everyone, I wanted to see if any other RMBP owners out there have been experiencing stability issues, specifically whole machine lockups to a grey screen followed by a forced reboot? This happened to me twice yesterday, once immediately after resuming from "sleep" and the second after...

Hello everyone, I have an hp ZR30w and i'm experiencing issues with the monitor randomly deciding to go blank. My setup is 1x gtx 480 plugged into the ZR30w as primary, apple 30" secondary, and a 2nd card pushing a dell 30". At random, probably once every day or two, the ZR30w will turn off and...

Hello everyone, I'm trying to track down an error in event viewer that has followed me across installs and across completely different hardware and is driving me insane! This seems to happen most often when the computer is locked (winkey + L). I'm on a very clean install (2 days old) of...

Hello everyone, I've been trying to find the best affordable real-time backup software for a desktop (win7). I'm looking to backup to a local NAS, not interested in cloud solutions. I ran crashplan for about a year to my NAS just fine, but their restore process is insane! They force you to...

Hello everyone, My friend is currently on leave from his deployment in afghanistan and has asked me to help build the smallest nas capable of holding 3-4 3.5" drives. We would like to run ZFS as the filesystem in a raidz or raidz2 for maximum reliability, the problem i'm having is finding an...

I'm going to be throwing together an all-in-one virtualized ZFS file server soon with parts i currently have but wanted to verify that the controllers/hardware i'm thinking of using will work without conflict. Parts I currently have, excluding M1015: Mobo: Supermicro X8DTL-i CPU: (2x) Xeon...

I'm just curious if anyone has any information on a G9/G9x successor? I have both the G9 and G9x and love them both, it just seems that it's been a while without a refresh?
