fatman1683 posted:How would one go about building an eSATA DAS? I'd like to have an external RAID box connected to my ESXi host, but the cheap off-the-shelf options don't have any kind of useful management interface, and there's a huge gap between the $200 models and the $2000+ models where there's basically nothing. Plenty of these do that: http://www.newegg.com/RAID-Enclosure-Subsystems/SubCategory/ID-509 There are two ways of doing it. One is the way you describe where the external box builds a raid set and exposes a single volume to the machine. The other uses a port multiplier and passes all the drives through the single eSATA channel. You probably want the first one. I don't have any experience with any of them, but SANS Digital sure does make a wide variety.

I think that depends. Do you want the box to handle the RAID management, or one of the VMs? I'm running ZFS, and my case is out of internal bays. I've looked at a few of the Sans Digital boxes to just pass raw disks via port multiplication and eSATA so I can use ZFS to manage the disks. Currently I'm trying to figure out if its more cost effective to buy one of the big Norco cases, or if one or two Sans Digital boxes are a more cost-effective option.

I've got an LSI 1068E card, and I think it might be bad. Is there a good exhaustive way I can test it before I just give up and buy an M1015?

I've disabled the write cache on the SATA port. I guess I should have specified the mechanical and maybe even electronic side of the action.

PitViper posted:I think that depends. Do you want the box to handle the RAID management, or one of the VMs? Basically I want to have a standalone box that creates the array and presents it to the hypervisor as a single volume. Then I can RDM it to the fileserver guest, and have a native filesystem on the storage box that isn't inside a datastore. This'll make recovery easier if the hypervisor ever dies, or if I just want to upgrade the hyp without having to do a host-side data migration. And yes, I'm aware that there are off-the-shelf solutions that do this. However, the inexpensive ones I've found have no management at all, and basically only allow you to create a single array from a set of buttons on the front of the box. The expensive, enterprise-grade DASes do have management, naturally, but there's no middle-ground of reasonably priced storage enclosures with enough management to make them useful. So if I could figure out how the 'device' side of a SATA interface is served and find a way to put a RAID array behind it, I could build my own storage server with an OS that presents to the hyp as a single volume over eSATA.

I used to have one of the HP MediaSmart machines running WHSv1 & it was glorious. That box's mobo died on me & I have been pining away for a replacement ever since. I really don't want to gently caress around w/ my data in Linux, and the drive pooling stuff in WHS was amazing. I know there's a few 3rd party options out there now for doing that, do any of them work? Synology NAS boxes seem like they'd be nice but the custom filesystem & price are turning me away. Would a custom mini-itx system be reasonable? Sorry, lots of somewhat undirected questions. From my perusing most of the folks in this thread are running linux-based systems so we'll see if this is even really the right place to be asking.

I'm looking for backup software recommendations. My house has combined HTPC/server (Win7) that all the roommates share. I want to start backing up my personal computers (Mac & Win7) to the server, but I'd like have the files on the server encrypted so my roommates can't browse through all my files while using the HTPC. I imagine the easiest way to do this is to have backup software running on my personal computer that encrypts the files as it tosses them onto the server. I'd also like the backup to either be scheduled (e.g. once a day/week) or manually triggered, rather than a live continuous backup (I don't want the backup service/program running in the background at all times). What backup programs can do this relatively painlessly? I'm also planning on having the server mirroring the encrypted backup online using either Backblaze or CrashPlan (both of which will encrypt the data again I believe). Are there any issues that could come up when using either service with already encrypted data?

Crashplan can be used for free to back up between computers, so it will work for everything you're talking about - your friends can all sign up for their own accounts and then you can share your server as a backup destination. You won't be able to see their files, they won't be able to see yours.

e:f;b, but still:Splinter posted:I want to start backing up my personal computers (Mac & Win7) to the server, but I'd like have the files on the server encrypted so my roommates can't browse through all my files while using the HTPC. Crashplan can do this. Set up the server with it's own Crashplan account, then send "friend" codes to the client machines, each of which is a different Crashplan account. Because every machine is a different user, nobody can see anyone else's files, and everything's encrypted anyway. The client sets the backup schedule, so there's no major concern about the server running the backup bits 24/7.

Sounds like CrashPlan will work. One question: does CrashPlan allow you to backup a "friends" backup online without paying for multiple computers? I gather I'd be running CrashPlan free on my personal machine, and CrashPlan+ on the server (since I want the online backups sent from the server). From the server, can I select my personal machine's backup as normal files to backup online, or will CrashPlan recognize it is another user's backup and require the family plan?

You can backup whatever with CrashPlan+. I'm doing the exact scenario you are explaining right now: 3 machines back up server, server backs up everything online.

Also since it's basically a customized linux distribution they publish their source code modifications and people have been able to compile drivers for extra hardware and get it working on third party devices such as the MicroServer. Similar concept as the Hackintosh.

Apparently ZFS replication knows your file structure better since it's block-level rather than rsync where it's file-level. That gives it the benefit of knowing about the snapshots and whether to duplicate the data. For example, if you cloned a dataset, it shouldn't transfer it but rsync would. At least that's my understanding of it from the Google searching I did.

Are the WD Reds really worth the premium for a NAS? I will run an Unraid setup and the drives will only store movies. So the only times the drives should be spinning is when I'm streaming them to my HTPC or I'm ripping/copying my movies over the network. I was thinking of getting 4 of these Seagate external and just rip out the internal drive: http://www.newegg.ca/Product/Product.aspx?Item=N82E16822178117 Good idea or worst idea ever?

Since I couldn't find anyone to tell me it wouldn't work, I grabbed a second dual-port PRO/1000 card from amazon for $50 to play with MPIO/iSCSI and see if I could make worthwhile gains over 1gbps for a single data stream. My desktop and my NAS are next to each other on the desk, and each is connected to the gigabit switch on a linksys e2000 with its onboard gigabit NIC (iSCSI doesn't touch this network). Each machine has an additional, identical dual-port Pro/1000 card, and the two machines are doubly crossed over with them with each pair on its own subnet. It wasn't too difficult to set up iSCSI via a guide, mount the disk in windows, and mash buttons until I figured out how to enable MPIO from that end. (This is freeNAS with a 5 disk RAIDZ2 and fast SSDs for cache and ZIL.) Also, anyone know if there's a way to do iSCSI without actually thick provisioning a virtual disk for it? Is there any way to just share my existing data as an iSCSI drive? e: Things seem to be working more or less as intended. CrystalDiskMark on the mounted drive consistently reports 136MB/s for sqeuential reads no matter how I configure the test. This seems to be consistent with the speeds I'm getting on large (>4gb) transfers that aren't cached. Smaller transfers from the cache are clearly faster but I'm not sure what's the best way to benchmark it. I tried copying a 4gb windows .iso back and forth between samsung 830 and NAS and it kept completing in 6-7 seconds which isn't even possible inside of 2gbps.
