The M620 does not have external SAS ports, and it also lacks a PCIe slot for a SAS HBA. The only M1000 blade that can connect to a SAS enclosure would be an M610x with an add-in PERC card. This would be an extremely strange configuration, to say the least, and is not supported. Blade servers are explicitly *not* supported with the PERC H800 cards, as documented here: http://www.dell.com/learn/us/en/04/campaigns/dell-raid-controllers?c=us&l=en&s=bsd&cs=04&redirect=1. However, even if it were possible to connect these components together, the first solution still will not work. The MD1200 does not support multi-initiator configurations; the dual (not triple) SAS ports can only be connected to two SAS ports on the same PERC card, and the PERC card must explicitly support the MD1200. Sorry to burst your bubble, but you need to go back to square one with this... there's so much wrong with your solution I can't even suggest how to fix it! BTW, if you already have an M1000e chassis, you should probably be looking at the Equallogic PS 4110M iSCSI array instead. If you don't already own a M1000e chassis, purchasing one to hold only three blades is... well... stupid. You could buy 1U servers (and two MD1200s, and a 10GE switch) to do the same thing for around 1/4 the price. If you really want blade-like equipement, look at the C6220 instead. That will give you four servers in a smaller footprint that doesn't require an electrician to hook up. Add whatever SAS or 10GE or ... cards you want; each node has a PCIe slot as well as two(?) mezzanine slots. -Adam Thompson athom...@athompso.net ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user

MD1200s 12 disk limit seems to fit quite nicely with 4-5 blades (2-3 mirrored disk each). Maybe you can scale-out having multiple proxmox clusters, each with his blades and disk enclosures. This gives you a cheaper start and more I/O bandwith. I'd chose this, but don't know what growth you expect for the cluster... also knowing what type of I/O do you expect would help. If you expect high I/O then you should consider less VMs per disk... In my experience usually the limit you hit first is disk I/O, especially with spinning disks...

Re: [PVE-User] problems with 3.2-beta
Hello Adam, thanks for your feedback. For help in your issues with migration or HA, please submit ONE thread for each single problem, multiple complex issues in one thread will lead to non-answers. Here I just answer to your ceph feedback: > 3. The Wiki page on setting up CEPH Server doesn't mention that you can > do most of the setup from within the GUI. Since I have write access > there, I guess I should fix it myself :-). [Martin Maurer] The wiki tells on which step you can start using the GUI: http://pve.proxmox.com/wiki/Ceph_Server#Creating_Ceph_Monitors Also the video tutorial shows what is possible via GUI. > Ceph speeds are barely acceptable (10-20MB/sec) but that's typical of > Ceph in my experience so far, even with caching turned on. (Still a bit > of a letdown compared to Sheepdog's 300MB/sec burst throughput, > though.) [Martin Maurer] 20mb? If you tell your benchmark results, you need to specify what you measure. Our ceph test cluster - explained and described in the wiki page - got about 260 mb/second (with replication 3) read and write speed inside a single KVM guest, eg. Windows (testing with crystaldiskmark). Ceph is not designed to maximum single performance, its designed to scale out, means you can get good performance with a big number of VMs and you can add always more server to increase storage and speed. You can do a simple benchmark for your ceph setup, using the rados command: First, create a new pool via gui, e.g. I name it test2 with replication 2: Now, run a write test: > rados -p test2 bench 60 write --no-cleanup __ Total writes made: 5742 Write size: 4194304 Bandwidth (MB/sec): 381.573 __ Now, do a read test: > rados -p test2 bench 60 seq __ Total reads made: 5742 Read size:4194304 Bandwidth (MB/sec):974.951 __ Main important parts for performance: - 10Gbit network - at least 4 OSD per node (and at least 3 nodes) - fast SSD for journal > One thing I'm not sure of is OSD placement... if I have two drives per > host dedicated to Ceph (and thus two OSDs), and my pool "size" is 2, > does that mean a single node failure could render some data > unreachable? [Martin Maurer] Size 2 means that you data is stored on at least two nodes. So if you lose one node, your data is still accessible from the others. Take a look on the ceph docs, there is a lot of explanation there. > I've adjusted my "size" to 3 just in case, but I don't > understand how this works. Sheepdog guarantees that multiple copies of > an object won't be stored on the same host for exactly this reason, but > I can't tell what Ceph does. [Martin Maurer] Size=3 will be new default setting for ceph (the change will be with firefly release, afaik) Via the gui you can easily stop and start, add and remove OSDs, so you can see how the cluster behaves in all scenarios.
