Good morning Matthias, While a ATTO benchmark shows full NIC load in both directions for a single connection, MPIO read performance is -now- horribly slow. A 128k ATTO transfer shows > 100 MB write speed, but only ~ 35 MB read. The settings are close to default: - 2 x i350 NIC (server), 2 x NC362 (i...

Good morning Anatoly,

I stayed with 4K as the difference between 4K, 32K and 64K has been neglectable during my tests.

Hi Jeff, Is it possible for someone to confirm if 10-20MB/sec writes are expected for your product when connecting via the ESXi software initiator? I'm getting wire speed when benchmarking from a 4 NIC ESX host to a 2x2 NIC StarWind HA Cluster: 4GBit. But it took me a while to get there. What does y...

Hi Anatoly, Totally agree with jeddyatcc - this should be the test based choice. Will be done as soon as the new drive arrives :-) I'll keep you posted. Already did some testing with the NTFS cluster size within a VM: No performance difference worth mentioning between 4K and 64K, base disk of the HA...

Good morning, Sounds great, please keep us posted! Short of a little problem due to misalignment of the 2003er VMs (will be fixed soon), almost everything looks fine now. Almost: Doing a storage vmotion of a 25Gig VM that is powered off takes 15 minutes. There are 3 NICs dedicated to iSCSI in the ES...

Any updates on this one? Still waiting for the pics

Good morning,

what NTFS cluster size should be chosen for iSCSI targets? 4K would be default, but I think I've read something about 64K being better for iSCSI targets.

Hi Max, as soon as the new NICs arrive for the 2 new servers I bought, I'll setup everything with w2k12. Hopefully this weekend. But I really think it's the NIC in w2k3-storage (Windows 2008 storage server), as the other windows 2008 box doesn't show any problems in the HA-Cluster with windows 2012....

Nope.

Hi Anatoly,

I performed the update just some minutes ago after the error reoccurred yesterday.

Good morning,

finally, here it is: Setup example for a low budget HA solution for SMB

Comments are welcome, projects as well

Hi Max, I guess the article doesn't mention one thing - binding 2 nics active is not supported. The way you do it is ok, however it can lead to failover issues if not configured correctly. The correct distribution should look the following - vSwitch1 Active - path to SAN1 Passive - path to SAN2 vSwi...

Hi Max, Had you any chance to upgrade the SAN? Do you have any update for this topic? I did and I have :-) See next post. BTW, one thing that I`d like to mention: you can show 2 nodes config to your customers and be sure that 3 nodes will behave in the same way. Another way is to contact sales and a...

Hi there, quick update again: - added an additional NIC to each ESX - reconfigured vSphere networking - changed MTU to 9000 not only for the iSCSI-vmkernel port but for the corresponding vSwitch as well ( :oops: :oops: :oops: ) No more errors so far. Benchmarking shows 75MB/sec writing, 220MB/sec re...
