I can use iSCSI MPIO to prefer the local target. I will run heartbeat over a separate subnet routed via a VPN over the WAN connection.

I want the VMs to primarily access the local partner, using the cross-DC link primarily for sync.

I'm thinking I will configure the disks as a 3.3TB RAID10 over 22 drives, which will do 500-1,500MB/sec, depending on the read/write sequential/random patterns.Įach host will be a Hyper-V server using Windows Failover Clustering, with CSV caching.

Each host will be 2-socket, 6-8 cores/socket, 144-384GB RAM, 24x 300GB 10k SAS on a single controller, running Windows Server 2012.Įach host will run Starwind HA targets, with write-back caching. The data centers are linked by a private line (PL) GbE metro fibre line, they are on the same subnet on a VLAN that spans the two DCs. I want to configure two hosts in two separate data centers for HA/DR. It will also be the good choice because your system will hopefully grow, so as the hardware requirements, so there will be oone day when you will require 10Gbps instead of 4x1Gbps cards. If you`ll use 10 RAID I can guarantee that you will need 10 Gig NICs. It’s up to the customer to determine the optimal stripe size. Performance of the HA will depend on the performance of the RAID array used. In some configuration smaller stripe size value like 4k or 8k give better performance and in some other cases 64k, 128k or even 256k values will give better performance. These 3 results should guide you to the optimal stripe size value to set. In third step set a smaller value and test again. Then set a bigger value and run tests again. As best practice we recommend at first step to set recommended by vendor and run tests. There are no exact recommendations of which stripe size to use. The performance of a RAID array directly depends on the Stripe Size used. A total of 20 to 40 VM's will be hosted in the failover cluster, eventually.įirst of all I'd strongly recommend to take a look at our Benchmarking Guide.Īlso, I'd like you to know that recommended RAID for implementing an HA are RAID 1, 0 or 10, RAID 5 or 6 are not recommended due to low write performance. The two or three cluster nodes are D元80 G8's also with 15K SAS drives, probably a small RAID 10 array each for the OS. iSCSI traffic will go over quad bonded Gigabit nics, or 10GB nics if highly recommended instead. ***edit: RAID 10 if recommended*** So that's 6TB or so on RAID5 with the hot spare, much less on RAID 10. Twelve 600GB 6Gbps 15K SAS drives in a RAID 5 array. How should I benchmark (ahead of purchase!) if the solution can accommodate the required performance? For example, I'm building (proposed) an iSCSI SAN on HP D元70's. I'm using top of the line everything in the hardware but I'm a bit concerned about disk throughput with the iSCSI SAN. Can we use less expensive SATA drives for the replication partner or will that substantially slow down the replication process? Or worse, slow down the primary iSCSI LUNs? Would it be better for performance purposes to break up the iSCSI array into smaller arrays using a separate controller or controller channel? If so I lose a drive's worth of storage for each RAID 5 array I create.Īlso, there will be a Starwind HA failover node. I can't have these guys buy $70K of hardware and services and find that the VM load is too great for the disk array. I know that the new E5-2650 CPUs are sufficient for the VM load. They might add an Oracle server VM or two down the road. Some VM's will host SQL 2008 server, some will be term servers, some basic Windows appliance servers. A total of 20 to 40 VM's will be hosted in the failover cluster, eventually.
