Backup Thruput with 10 Gbit NIC teamed with 1 Gbit for Fault
Author Message
Post Backup Thruput with 10 Gbit NIC teamed with 1 Gbit for Fault 
Research notes I've made, it appears do'able - will post the progress
after we implement this;

Configure NIC Teaming with HP Proliant:

Network Fault Tolerance (NFT) with Preference Order

The need for ranking certain teamed ports better than others can be a
result of unequal speeds, better adapter capabilities (for example, higher
receive/transmit descriptors or buffers, interrupt coalescence, and so
on), or preference for the team’s primary port to be located on a specific
switch.

Preferred Primary Mode:
The last mode available for NFT is Preferred Primary mode. When choosing
Preferred Primary mode, the operator is presented with a drop down box to
select the “Preferred Primary Adapter”. The operator should choose the
adapter that, for a particular reason, is best suited to be the Primary
Adapter.

When an adapter is chosen as the Preferred Primary Adapter, it will be
used as the Primary Adapter whenever it is in an operational state. If the
Preferred Primary Adapter experiences a failover event, the NFT Team fails
over to a Non-Primary Adapter. If the Preferred Primary Adapter is
restored, the Team will then initiate a failback to the
Preferred Primary Adapter.

Folks:

Config: Networker 7.6.1 - Windows 2008 - Proliant G7 32 GB RAM, recent-
model Cisco switch with limited 10 Gbit ports, many 1-Gbit ports.

Plan: High speed thruput for Backups over 10 Gbit LAN port, but need
Fault-
tolerance by teaming with 1 Gbit network card.

Question: Can you Team 10 Gbit nic with 1 Gbit nic - in Active/Passive
configuration; 10Gb ACTIVE, 1Gbit Passive-mode. While 10 Gbit is
Active/Up, we would like full 10Gbit speed (do not want watered-down 1Gbit
performance on 10Gbit card, due to incorrect Teaming). What is the such
Active/Passive teaming for this 10Gbit and 1Gbit Active/Passive mode. If
it matters - these are HP Nics on Proliant G7 servers.

Details:
--------
Planning for a high speed data thruput onto our Networker AFTD device
which is capable of ingesting/writing upto 250 GBytes/second (over 2
Gbits/sec). So we obviously want to use its 10 Gbit card, and also put 10
Gbit card on StorageNode (which will also our Windows filer-server) for
best possible pipe performance.

We are limited on our Network switch/licencing on 10 Gbit ports. We are
only left with 2 10-Gig switch ports - one port for AFTD device, and the
other port going to StorageNode+FilerServer. Since we are going to have
limit of ONE 10 Gbps port on switch, we can't hope to Team/Bond another 10
Gbit card. All we have left on Cisco switch is 1 Gbit ports. We would like
to team 10 Gbit adapter with 1 Gbit adapter on our Windows Server --
"Active" using 10 Gbit card (at its peak speed), while team/bonding it
with 1 Gbit nic card in "passive" for Fault-Tolerance purpose.

Our "Goal" is get 10 Gbit Backup speed so long we can, but if 10Gb
card/nic/switch-port fails, we would like to be UP on the teamed 1 Gb
port. We would like Active/Passive mode running 10 Gbps active. We are
trying to AVOID load-balancing (which will most likely reduce 10 Gbps down
to 1 Gbps once teamed with 1 Gbit nic, YUCK!).

We would love to take advantage of the 10 Gig speeds for fast Backups.
Remainder of our network is 1 Gbps (teamed/ether-channeled for servers
802.3AD?) for performance and fault-tolerance. Our Cisco network-switch
has sufficient backplane bandwith.

Note: Our AFTD device is capable of Teaming, but we will keep it on single
10Gbit port, due to switch-port availability. Beside, its not as critical
as our Filer-Server+BackupNode.

Thanks
