Once you've added that session, go back and add more, using your different iSCSI adapter IPs as the initiator. If it's not that smart, then enter individual IPs of the NICs. If it's smart, like an Equallogic or something, you should just be able to pick what IP it indicates is its portal IP. What you pick for the target portal IPĭepends on the device. From there, manually select the initiator IP. On the "Connect to target" screen, use the "Advanced" button (don't forget the "Enable multi-path" checkbox). Note that if you've already set up a bunch of sessions, you'll want to knock them out of the Favorites tab before you start adding more sessions or you'll get a lot Once you get in there, use the "Add session" button to add individual session. Instead of using the "Connect" button from the front page of the iSCSI tool, use the Properties button: So, when you're configuring iSCSI, add connections individually. Preferably, each physical adapter at the target will also have its own IP.

Their MAC addresses on a single port, which means there will be no load balancing. That's because all the team's adapters will have to register Basically, if the physical switch connected to the target doesn't know about the team, it's no good. You may team at the target level, but it should be cooperative teaming, as in 802.1ax or 802.3ad.
Each adapter used in the iSCSI initiator needs its own IP. Teaming iSCSI from the initiator leads to unpredictable and sometimes problem-ridden results. The initiator adapters should not be teamed. If MPIO is OK, or at least you think it's OK, keep reading. If it's not checked, you'll have to check it and reboot.

Get a driver or a DSM for your iSCSI target. If you can't get it to work after the following directions, you need to If the iSCSI box is already checked, MPIO is probably OK. If it only shows the Vendor 8Product 16 entry, then flip over to "Discover Multi-paths". It's in the iSCSI configuration.Ĭheck MPIOCPL.EXE first. MPIO-capable, that's probably not an error in MPIO configuration. We'll go with the perception thing.Īnyway, when you're looking at the MPIO status, if your policy is anything other than Fail Over Only and any path is marked as "Standby", that means that MPIO believes that it is a duplicate configuration for another path.
Pretty easy to check with a Task Manager -> Performance or Performance Monitor. To anything above 1) but on a pulsating traffic you'll never see LQD hardware utilization on the level you'll see it with RR. So on a heavily loaded system LQD will work more or less the same as RR (think about it as setting number of outstanding IOPS with VMware MPIO The next IRP DSM will check for completion and use either first one (if its lucky to be free) or second and so on. With Least Queue Depth bunch of IOs will be delivered to the first path (not one IO!) then on It depends on how you look it :) Technically Round Robin will use also only one connection at a time, it just will switch them frequently and on a constant basis. That can happen if you just create multiple sessions to the same portal without specifying unique initiator IPs. Your initiator-to-target connections need to be set up in a way that they don't re-use the same IP pairs. The only MPIO method that doesn't balance across multiple paths is "Fail Over Only". Before you'll take this one to production rebuild the array to have RAID10 and compare the numbers RAID5 (any partity RAID) is not the best choice for the primary VM storage (to say at least) without log-structure (primary or initial one like VMware VSAN does). How could I have configured this incorrectly, or is there a bug in this OS? Please help. I need this copy process to happen at the maximum possible speed.
It appears that the copy process is rate limited. On the Hyper-V installation (not in a VM), I get speeds in excess of 700MB/s. If I copy a file to a separate folder on the same virtual machine I get the same throughput. When I copy between to or from a virtual machine on this hardware I get a maximum copy speed of 111MB/s (roughly 1Gbps). The server has an iSCSI Dell PowerVault MD3600i with 10x15K SAS drives in a RAID 5 configuration.

I have installed a Hyper-V server on a Dell PowerEdge R720 (128GB) with Windows 2012 Datacenter.
