Does anyone know how to make a RAID 10 in Freenas? I can't seem to find it anywhere, all the guides point me to raid 5 or 1 or 0 but not 1+0? Am I missing something or does freenas not do this. Yes this is software emulation

ehzorg posted:Yep. If I were you this is how I would do it, Order something like a NX3100 Get 10-20Tb on that. 7.2k drives will give you a decent amount of I/O(1k-1.25k) Rate performance on that, see if you are maxing out I/O. Order more to fit space and I/O requests. Provision Luns and Arrays per servers and Clients as needed. You are going to need more than one storage device anyways, might as well start it off as a modular storage array. My previous employer I worked with a PowerVault 20TB NAS RAID 0 all my VM server, hosted: Sharepoint/Lync/2 Domain r2 serves/NFS/DFS and backups and was able to server 150-200 clients with ease. Don't run it in raid 0 but Raid 5/6 should give you ample performance over daisy chaining externals

I haven't toyed around too much with things other than DRBD and started looking at Rsync, from my light googling it looks like it is just file level instead of block level.

I haven't run perfmon on the current servers in question (and was actually spinning up some logged performance stats earlier today) so I'm not sure where to start. I've been pushing to virtualize for a while, since our SQL server is a single socket, and our voicemail server is a dual PIII, so off the cuff we're a good candidate for server consolidation. Is there a way to get decent quotes with almost no information up front? Dell will let you build/customize your own NAS devices and get a quote instantly. NX300 and NX3100 are good if you work in a medium size company, and some R210's are cheap good first time virtualizing type servers. VVVV- answer that but, if you just need something to go off of Servers storage + Essetianls plus kit should run you right up near 25-26k, and if you don't already have some get some gig switches and make a network just for storage.

A lot of our clients are wanting cloud solutions for things now, so I am trying to piece together a "cloud" storage solution. I was thinking 1)Lease out a NAS device to clients 2)NAS Device holds local backups for client for faster redeploys here is where I a a bit torn A)Rsync/Bacula to our "private cloud" during the night, compress further 7z => to our cloud server Pro's more redundancy getting data to Client if NAS fails and backups are needed is faster our clients could get a full backup by us driving over to them with an external of backup from the past two weeks Con's More steps B)NAS device runs Bacula=> on stie compress=>upload to cloud Pro's We don't clog any of our WAN, backup depends on clients connection We don't have to use any storage Con's Slowish Kinda torn between these two. I prefer A more offer the customer, but B is more simplistic. Plan A would be 55c/GB + 50/mo + ~150 for NAS setup/deploy Plan B would be $10/mo per PC(no charge per/GB) + 50/mo + ~150 NAS setup deploy Thoughts? Which would you all choose given the option?

Anyone have some advice for setting up an Active/active NAS? Openfiler to my knowledge only does active/passive. I know Centos supports GFS so doing an active/active would be doable, but any suggestions about other distros or what not to look into for this would be appreciated. I tried asking a few people in my storage/Vmware class most everyone answers with. "Oh we just pay the EMC/netapp people to set it up, we don't really touch that too much"

NippleFloss posted:You probably get that answer because it's not a common thing to do because the benefits of active/active for NAS aren't that great. Any single export or share is only going to be accessible from a single physical host, just as it would be in an active/passive config. Yes, you can provide a better balance between all exports if you have active active, but if your intent is to run both hosts at above 50% utilization then when you do have a failure event you're going to be hosed. Yeah I know but assuming your SLA's are set properly, active/active can be a good move even in a host failure(other than users noticing it is slower than usual). Running with active/passive right now and just wanting to explore more into storage. I guess I thought most SA's would know about setting from the ground up Active/<passive> or <active> storage. But is seems most people just pay netapp/emc/dell/oracle to do it, which struck me as odd

Alright my current work is using Openfiler virtual nas devices for Shared storage, this is working thus far but I would really rather get a SAN going just need to bump heads with some of you all. I posted in the VMware thread but have gotten some updated numbers and feel this thread a touch more appropriate. Here is the Equipment I want to buy, all are NX3100 Powervaults, OS drive RAID 1 15K SAS 146GB, Dual PSU's, Dual 10G/Ethernet, 2x1GB backend connectors, Write Cache is 512MB on all, Quad cores + 6GB ram on each. NAS A - 10 600Gb 15k drives RAID 5 + 1 HS High end disk I/O intensive storage, SQL, web facing servers, priority VDI, Small NFS share NAS B - 10 1TB 7.2k SAS drives RAID 5 Backend servers, Domain controllers, non priority VDI, other VM's, other NFS servers NAS C - 10 2TB 7.2k SAS drives RAID 5 + HS 1 per array Backup server 10TB will be provisioned for GFS/DRBD on an ACTIVE/ACTIVE with NAS B 10TB deduped and store backups of critical information, after X days file sent to Crash Plan These will run Centos 6.2, primarily iscsi w/ jumbo frames set at 9000. I might however plan to run the data stores over FCoE since it seems the x520-T2 supports it, cutting latency out, and TCP overhead. B and C will do Active/Active storage, then iSCSI to the esxi boxes, A will use C as a backup device All this will hook up to 5 Esxi servers running VDI's and other drives, and 3 Servers running Esxi 4.1, 50+ vm's mostly windows clients and Servers. I know in about 6 months we want to expand our VMware working with clients, hosting solutions, demonstrations for clients, and other things so I find it better to get the ball rolling. I would love to go with EMC or netapp, but I can get this up and running for around 30k. Open for other ways to go about this, I might just do 2 600GB 15K drives ~12TB w/ Active/active, then backup to a NAS C with 20TB, but I like the idea of tiering my storage.

Cpt.Wacky posted:I don't have any comments on your design but I'm in a similar position of needing a real SAN. I'm curious what led you to the Powervaults over something like Equallogic. Is it just price? Worked with them before at other places, they are decent for the price, never had gripes with them compared to HP's solution of NAS devices. The fact I can dig down and customize them via web interface is nice too Nukelear v.2 posted:Why use NAS at all, why not just get some MD3xxxi's and just present iSCSI and use VMFS to your hosts? Or buy some EQL if you get a bigger budget. I could go that way but I have some 10GoE connections and 10g FCoE adapters on the hosts, I would like to put those to use. Seeing how MD's start at 18g for one device, it doesn't look cost effective either. skipdogg posted:CF, I can't give exact numbers but our pricing on a VNXe box from EMC with close to your data capacity isn't far off that 30K mark. Yeah I am going to look about getting a larger write cache though if I go raid 6.

Nukelear v.2 posted:So going to backup really sounds like a good plan, you want that call at 3am that you entire Web/SQL infrastructure is down? Can your cheap/slow tier actually handle running your production traffic at anything resembling your previous speeds? How well does vmware do when it's storage backend goes to hell? Your own first post in the VM thread is don't cheap out on storage I would say you are right if I had existing SAN/NAS to go off of, but here is my situation Right now our SQL/Web/VDI infrastructure is best hosted on a server with DAS 8 1TB 7.2k SATA RAID 5 256MB write cache. WE HAVE NO CENTRAL STORAGE. It isn't too slow for our needs but definitely slower than it should be, people are starting to drop the line "why is everything so slow". VDI is all on DAS put randomly on hosts through the cluster, same with other servers, HA/FT/vmotion/sDRS/DRS is non exsistant even with out Enterpise Plus licensing. A host failure right now would be hell more difficult recovery, than dealing with some sql servers on a backup NAS. No I am not trying to "cheap out" I don't have a huge budget to work with here. I am trying to get the infrastructure what it needs to get it somewhat better, more redundant than what it is at right now. I would love to spludge if I had the funds to do it, and go get some NetApp/EMC equipment but I don't have the funds for it. The 2 MD1200 would be great to get, until I realize I have to address 8 hosts... So I need 16 SAS cables, and then 2x8port switches... and then 8 additional SAS cards... I could go SAS => 2 hosts(which I would need some SAS cards for) then run VM iscsi servers, but that is adding a good amount of added layers that are needed to go through, just to get my data to where it needs to be. That would more than likely push my over 30k. Dilbert As FUCK fucked around with this message at 23:57 on May 23, 2012 |

The VNX line is a direct response to NetApp and NetApp would be the obvious competitor. If it is like what most sales reps do, $IT_manager went to lunch with $EMC_rep, and discussed what they have in the cheap end and the VNX 3100 came up. The main requirement is replication between sites, dedupe is a nice bonus they would like but aren't pushing for it outside of a nice to have. Depending on what my budget is will depend where I go, seeing how they listed the VNX 3100 my guess is they want to go on the cheaper end.

I currently don't see the need to introduce any NFS storage since iSCSI has been meeting my needs, but seeing the management of some other block storage devices would be cool. Sounds good you can pm me and I'll give you my cell to do whatever with. I use DRBD/rsync on some of my Gov, bank, or medica deploys where data has to be in two separate boxes. If you copy it from flash it doesn't hit the production SAN/NAS which is great.

Might be more a networking question but, Is anyone here actively using FC for anything other than high end transaction servers? I've had a few customers who have existing 4Gb/s FC networks for their SAN looking to upgrade and I usually just go with 10Gb to run ISCSI or FCoE. But I get those "Is this guy really suggesting that?" moments from some people on ISCSI/FCoE. It might just be dinosaurs in the IT management sector who haven't looked at what is going on around them, and think FC @ 8Gb/s is the poo poo. Normally I'll sell the admins pretty fast when I show them the performance numbers, and sell the managers when I show them the cost, performance, and manageability of ISCSI/FCoE. Just gets annoying having to repeat myself over and over, didn't know if anyone had some view points they could shed some light on.

Last I checked, Cisco doesn't even have a convergent switch that does 8GB (much less 16GB), so you can't possibly try to convince customers to do a gradual switchover from traditional FC to FCoE. Yeah the Nexuses are there and workable however cost a small fortune for the price. I don't have anything against other vendors but company policy and all that dictates what I can/cannot sell or push to clients. That's a good analogy
