The full list of new features is:
| Dual-hop FCoE Support |
Extending convergence for Flex-10 and FlexFabric |
| Bandwidth Optimization |
Min/Max for NIC Bandwidth |
| Priority Queue QoS |
Prioritizing critical application traffic |
| SNMP MIB enhancements |
Improved monitoring and troubleshooting |
| sFlow monitoring |
Monitoring and planning at flow level |

There are a number of dependencies for VC 4.01
- Onboard Administrator – v3.70 recommended, 3.11 minimum
- Virtual Connect Support Utility (VCSU) – v1.8.1 or later
- Virtual Connect Enterprise Manager (VCEM) – v7.2 (Will work in older VCEMs in compatibility mode, i.e. no new VCM features will be supported)
HP says Service Pack for ProLiant (SPP) 2013.02.00 is recommended as a Baseline Release Set but VC 4.01 has also been tested with SPP 2012.08.0, and SPP 2012.06.0 (B). Not quite sure what this means as if it has been tested with the previous versions they should be the minimum. Knowing the historical issues with firmware incompatibility, I would suggest ensuring you have SPP 2013.02.00 on your blades first.
It’s worth noting that VC 4.01 is not part of any particular SPP package. HPSUM or the VCSU can be used to upgrade to VC 4.01 after you have upgraded your blade firmware.
The Emulex firmware version for the built in LOMs on a G7 Blade server (HP NC553i or NC551i) or Mezz card (HP NC554m) or the CNA LOM added to a Gen8 Blade server (HP 554FLB) need to have their firmware upgraded to support dual hop FCoE. The latest Emulex firmware version for the NC55x controllers is currently 4.2.401.2215. This firmware is NOT included in the SPP 2013.02.0, but it can be downloaded as a separate standalone update tool (bootable ISO file) or as a HP SUM component.
HP Virtual Connect 4.01 can be downloaded from here
You can read the Release Notes which detail the list of other fixes and also highlight some of the issues so a must read before deploying in case they affect you.
You can also read the User Guide and the Setup and Installation Guide
I have not updated my HP Virtual Connect Flex-10 & VMware ESX(i) pre-requisites post yet to reflect this new version as with such a major change it’s worth checking everything works as advertised so get testing!

VMware and HP have both released advisories which say you shouldn’t use HP Virtual Connect in tunnel mode if you are using vCloud Director Network Isolation (vCDNI) which is MAC-in-MAC encapsulation.
There are two network modes available with Virtual Connect, Tunnel Mode and Mapped Mode.
When using Tunnel Mode, Virtual Connect passes all tagged and untagged packets through the Virtual Connect switch down to select blades where the VLANs are split into port groups. The uplinks are therefore considered dedicated uplinks as control over which VLANs are trunked is done at the upstream switch and so you can’t have a different set of VLANs going to Blade 1 and Blade 2 while still utilising the same uplinks. You could obviously have separate sets of uplinks for Blade 1 and Blade 2 to achieve this. The advantage of tunneling mode is only having to specify your VLANs once at the upstream switch and being able to pass all VLANs down the same trunk to multiple blades and only having to manage VLANs at the upstream switch and port groups on the ESXi host or within the vSphere Distributed Switch.
In Mapped Mode mode, the Virtual Connect switch examines all the VLANs and by defining Ethernet Networks for each VLAN on the Virtual Connect switch you can selectively pass down all or some of the VLANs down to the blades. The uplinks are considered shared as you can trunk all VLANs you will need for any blade and for example have some VLANs going to Blade 1 and other VLANs going to Blade 2 but sharing the same uplinks. In order to do this you have to create separate Ethernet Networks for every VLAN (possibly two for redundancy) and manage VLANs at both the upstream and Virtual Connect switches as well as port groups on the ESXi host or within the vSphere Distributed Switch.

Emulex has released a new set of drivers and firmware for use on Gen8 and G7 HP Servers including blades with both VMware ESXi 5.0 and 5.1.
Driver:
Emulex be2net nic driver version 4.2.327.0 which is included in the HP Custom Image for VMware ESXi 5.1 February 2013: VMware-ESXi-5.1.0-799733-HP-5.34.23.iso and HP Custom Image for VMware ESXi 5.0.0 Update 2 February 2013: VMware-ESXi-5.0.0-Update2-914586-HP-5.27.20.iso or can be downloaded separately from VMware.
Emulex has also released a newer driver version 4.4.231.0 which is available from VMware but this isn’t supported as yet by HP.
Firmware:
Emulex firmware version 4.2.401.605 which can be updated using the Emulex OneConnect-Flash .ISO.
There was a 4.2.401.6 released but this has been superseded by 4.2.401.605 which fixes a number of issues.
I have done an extensive update of my HP Virtual Connect Flex-10 & VMware ESX(i) pre-requisites post which includes these new Emulex drivers and firmware.
I have had the pleasure today of presenting at the second UK VMware User Group. at the National Motorcycle Museum in Solihull, near Birmingham.
My presentation was titled vSphere Networking and Converged IO with Blade Servers.
I discussed how converged networking incorporating 10GE and FCoE is become more important as we try to utilise bandwidth more efficiently which is especially important with blade servers which have limited IO expansion. I explained the architecture of Cisco UCS and HP Virtual Connect as examples and how they can work with vSphere.
I went through some of the IO convergence options and also how to still protect your traffic by using either physical or logical separation or software.
No need to repeat everything else in this blog post, you may as well have a look at the presentation and best of all plan to attend a VMUG near you!

HP Blade chassis are integral to many IT infrastructure deployments. Within each chassis there are multiple components: for example Onboard Administrators, network switches running maybe Virtual Connect and the blade servers themselves which contain SSD/HDD drives, Nic or HBA cards, iLOs and motherboards.
All of these components require firmware to run and many of them are from different manufactures such as Nic cards which can be made by Broadcom, Intel or Emulex. Managing this firmware can be a frustrating and time consuming process which adds another management layer separate from the Operating System, applications and even HP drivers installed on the actual blade servers.
HP has previously had a very disparate way of managing it’s firmware and drivers. Different firmware and drivers had to be updated with different tools and was often very little or no coordination between the different updates causing any number of issues.
HP seems to have responded to customer frustration and is now coordinating their firmware and driver update procedures.

HP has released a new firmware version 4.1.402.20 of its Emulex OneConnect 10Gb Ethernet Controller which is used in HP G7 Blades.
The June HP Service Pack for ProLiant 2012.06.0(B) had a 4.1.402.8 firmware version so it looks like it only had a lifespan of a month and has now been superseded by 4.1.402.20.
Unfortunately it doesn’t look like the HP VMware Recipe for June has been updated http://vibsdepot.hp.com/hpq/recipes/June2012VMwareRecipe1.0.pdf
The installation is as before and requires you to boot off an .ISO and update manually. (I have a dream that one day…)
Before June the firmware version recommended was 4.0.493. I can’t tell what the enhancements are between 4.1.402.8 and 4.1.402.20 as the release notes for 4.1.402.20 only list the resolved issues from 4.0.493.
BladeEngine Firmware
- Increased RSS queues for Rhel drivers.
- Fixed W2K8 graceful shutdown on NC552 adapter.
- iSCSI not working when priority fields are used.
- 554FLR-SFP adapter, FCoE Path Multipath Recovery Failure, SLES11 SP1 x64
- FCoE port sometimes doesn’t login after VC module failover, w2k3
- Fix support for TEMP_DEAD and ALOM_FAN_ON_AUX on Gen 8 servers
- Correction to OCSD to prevent DMA conflicts with LPFC driver
PXE BIOS
- NC553i adapter using wrong IP for gateway during Tftp
- BE2/BE3 based adapters, PXE Hang
- BL465cG7 PXE boot stops and is not coming up in RDP
iSCSI BIOS
- SCSI SAN boot fails when DHCP Vendor Id is used for BL420cG8
- Smart Array shows EBDA Error when ELX iSCSI Boot LUN configured
UEFI NIC
- Dynamic link update is not working with NIC UEFI driver
Technical Tips
- When updating HP CN1000e and NC550SFP products, use either the OneConnect-flash.iso or the Elxflash Offline tools. Either method will update the ILO image for the Network Communications Services Interface (NCSI) side band support. This procedure requires a power cycle after flashing. This tip does not apply to network cards that are version 4.0.360.15 or later.
- Before you update your host drivers, update your firmware using the available online tools.
I’ve updated my post: HP Virtual Connect Flex-10 & VMware ESX(i) pre-requisites
