Do you have the LSI cards configured to just to SAS to SATA translation and then let XPEnology do all of the RAIDing via software? I feel like I'm between a rock and an expensive buy because the rack I already have (the one listed) is a short depth thing because I didn't want to spring for a big one when I didn't have equipment for it at the time, now I'm wishing I did because I'm limited to a short depth server chassis, or having this thing hang out the back until I buy a bigger rack. Either way I end up spending more money than if I had just gone with the bigger rack to start with. I'm leaning toward just going with the Norco 24-bay and be done with it, that give me tons of space to expand, and plenty of space inside the chassis to work.

I hear you there, but I'm looking at it more for the Sata PM role. I've been scraping the internet trying to find out what the pieces are that would go into a medium (24) or large (60) disk array. Another thought that came to me was to set up a single beefy master/head server and then be able to slot in multi-disk slave boxes that would connect via...SAS? so the master can delegate. Part of what I'm really looking for is a primer in large data storage system design. Without knowing what I don't know, I feel like I can't find the info I'm looking for.

That's a great video. You explained what to do, did it in a logical way, and more importantly why you have to do that. *edit I'm interested in what else you have in your 24bay Supermicro build. How did you multiplex the SATA (SAS?) drives onto the motherboard? the Mobo you list only has 6xSATA 3Gb ports, but you've installed 24 drives!

Alternatively, Here's another build that I'm considering: Chassis: Norco 4U 24bay Hot-Swap PCIe Expansion Cards: One line from this list, but I have almost no knowledge beyond a few hours of google and youtube videos about setting up a proper SAS subsystem. 2x 3ware 12 Channel 2x Adaptec ASR-31605 16 channel SATA 4x HighPoint Controller Card Rocketraid 2720SGL 8 Channel 4x Intel SRCSASBB8I 8 Channel 2x http://www.amazon.com/Adaptec-ASR-51245-2268100-R-300Mbps-Controller/dp/B01DBO0LRI]Adaptec ASR-51245 2268100-R 12 Channel 2x Adaptec 51645 20 Channel or just go without the SAS connectors and do straight SATA 2x Ablecon PEX10 10 SATA Post This gets pretty pricey very quickly, though it does allow for serious expand ability considering I'm looking for a quick 10TB fix and longer term growth. I would love some good suggestions for reading about how to design/manage a SAS based build. Why are they so expensive? Benefits vs using common SATA 6Gb/s?

This is an extension of my current data warehouse. I'm a bit of a hoarder. Archiving photos, system backups, VMs, software, media, raw disk rips, and of course my wii game backups. Plus I serve a bunch of the same functions for other family members, friends, and neighbors. It doesn't need to be rackmount, but I'm really trying to move to using rack mounted systems because of space conservation and for the ease of organization.

I'm coming from 5 years using Synology devices, currently running a DS1813+/DX513 with 13x4tb (10-2+1) and completely loving it. However I am hitting my roof on storage and don't really want to drop 2500 on a DS3615 unit to make the next jump in capacity when I already have a ton of old desktop hardware lying around from the last upgrade I did to my gaming rig. Enter XPEnology! This is fantastic and I'll be hoping to pair it up with my main Syno device as a secondary unit, cram all my old drives in and get some cheap ones on the used market, planning to upgrade them later on once I have squirreled away more cash into the "ongoing tech upgrade" fund. So since this is my first time, I am not familiar with building hardware into a server chassis (I'm going to mount this thin in my short depth rack 19x19, designed for AV). I've spec'd out a handful of parts that I'd like to get checked by this fine community for comparability to make sure that what I buy will work, and if not, pick different parts. Here goes! [spoiler=Parts List]Chassis: (only one of these) Rosewill 2U Server Chassis NORCO 4U RPC-431 Logisys 4U CS4801BK PSU: EVGA 500 B1 80+ BRONZE, 500W Mobo: (only one of these, depending on fit) Intel Z77 Intel H67 RAM: 4x4GB SDRAM DDR3 1333 (PC3 10666) Model F3-10666CL9D-8GBRL CPU: Intel Core i5-2400S PCIe Expansion Cards: 1x Intel I350-T4 2x Marvell 88SE9230 Cables: 9x Straight 6.0 Gbps SATA III Cable - 24 Inches 3x 4x SATA Power Splitter Adapter Cable 1x 2 Port USB Motherboard Header Rack: Navepoint 15U Shelf Shelves Rail Rails 1U Thoughts? Has anyone used any of these parts? Do you think it will work, or even fit? Ideally I'd like to cram as many drives into the space as possible, Hot-Swap externally accessible would be great. I'm really not married to a chassis yet, I just want the most 3.5" bays for the money, and the smaller the better. I'd pay a bit more to have a smaller chassis with the same number of bays, but the key is that the it fits into the short depth that I've got to work with.
