After recently working with the HP Virtual Connect Flex10’s in a HP C7000 blade chassis I have decided to blog about a few of the things I have learnt. What is a Virtual Connect Flex10? OK I’m going to cheat on this bit, below I have included the HP video on VC Flex 10’s it does a very good job of explaining exactly what a VC Flex 10 is. So what this means for us is that, for each Flex 10 connection in our blade server, it will offer us up to 4 network connections (Flex NICs) that can be fine tuned between 100Mb to 10Gb.

With two Flex 10’s we can then ensure our networking is fully redundant. We are then able to uplink our Virtual Connect Flex 10’s with as little as 2 10Gb connections to our Core network infrastructure. With the amount of NIC’s required in your average ESX build this makes FLEX10’s very attractive when deploying HP Blade Chassis.

HP Virtual Connect Flex-10 10Gb Ethernet Module HP 1/10Gb-F Virtual Connect Ethernet Module Firmware The first thing you will need to do when using the Virtual Connects is upgrade the firmware, after a bit of searching on the internet I found there were numerous issues reported with older firmware. Firmware for the Virtual Connect Flex 10’s can be found here >>I found the descriptions of the downloads very misleading and in the end found out I had to use the FC firmware even though I had an Ethernet module! I found the easiest and most reliable way of doing this was to use the Virtual Connect c-Class Virtual Connect Support Utility. This is available from the Once you have downloaded and installed the utility you will be able to use it to connect to your blade chassis and perform several tasks on your virtual connects. If you have a current configuration on your Virtual Connects ensure you run a backup of the configuration first encase you run into any issues. Wifi Adapter Untuk Hp Java.

Once you have backed up the configuration you are able to apply the firmware update I also found the Bay command useful when I had to only update 1 module on a replacement module after an initial failure. My Scenario In my scenario I was working with an HP C7000 blade chassis, numerous HL BL460c G6 server blades, two HP Virtual Connect Flex-10 10Gb Ethernet Modules and two non stacking Cisco switches. I was also working with iSCSI based storage. This is by no means a recommendation of hardware but simply what I had to work with in my scenario. Free Download Program Antenna Book By Kd Prasad Pdf Printer. The HP BL460c G6 server blade comes with 2 x LOM (LAN on Motherboard) connections. This means we are able to provision 8 FlexNics in total, these would be spread over two virtual connects located in Interconnect bays 1 and 2.

Virtual Connect Configuration In my scenario I would be using a single CX4 connection from each Virtual Connect to uplink to each of my core switches. As these two switches are not stacked together, only uplinked the virtual connect would be configured in an active / passive configuration for failover. To accomplish this I created a single Virtual Connect domain with both virtual connects being members of this domain. A single Shared Uplink set was then configured which both CX4’s were part of.

The relative VLAN’s in my network were then created inside the Virtual Connect Networks configuration. A server profile was then created for each ESX host, 8 FlexNics were configured for each host, as I like to tag the traffic on the ESX side, I configured the links to allow multiple connections and selected the relevant VLANs to be assigned to these NICS. The only exception to this was the vMotion NICs, these were configured with no uplink and were assigned directly to the the vMotion network that had been configured, as all the ESX hosts were located in the blade chassis this meant all the vMotion traffic could travel across the virtual connects. A couple of points to consider when designing your Virtual Connect environment is that a VLAN may only connect to one FlexNIC per LOM. This means that you can run into difficulty if your service console is on your production network. As you wouldn’t be able to assign your production VLAN to your Service Console portgroup and to you Virtual Machine Network portgroup. To avoid this you can move your Service Console network onto a management VLAN and route as necessary between this VLAN and your production VLAN.
