RE: Hyper-V NIC utilization
Currently they are on a 22MB/2MB connection from Entouch, they have a BES and are migrating to Exch 2010 from 2003 - heavy BB and email usage, not as much remote usage, only a couple of minor-staffed remote offices with site to site VPN connections - they are a community residential association.

RE: Hyper-V NIC utilization
Depends. I think I read a best practice that said at least two separate connections. One for guest access and one for host management. Possibly a third for backup and fourth for iscsi if needed.

RE: Hyper-V NIC utilization
I have been using Dell R610 servers to move many of our physical servers to HyperV. The R610 has 4 NIC Ports and 6 SATA drives. I am creating 3 RAID1 volumes, one for OS and one for each VM. I am assigning each VM its own NIC. I would suggest doing the same if there are bandwidth intensive applications on the VM. I do have one R610 with 6 VM servers and have combined NICs on some of them, but they are low bandwidth. (Vipre, Time Clock, etc). I have not seen any performance impact from combining the NICs. However, if you have them, why not use them?

RE: Hyper-V NIC utilization
You should consider aggregating 2 or 3 of the NICs and using them for guest traffic in a way that provides redundancy. Use a separate NIC for management. -ASB: http://about.me/Andrew.S.Baker Sent from my Motorola Droid On Mar 11, 2011 11:16 AM, Jay Dale jd...@unetek.com wrote: ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/ ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
RE: Hyper-V NIC utilization
1. How many NICs you use depends on the load and bandwidth requirements of your VMs. Use one NIC for managing the host and one or more for the virtual network connections (aggregated or dedicated to specific VMs). 2. I would enable static addresses for all, or at least DHCP reservations. 3. You can only have one default gateway. You have to configure the routing for the rest of the NICs with the route command line.
