Last week I’ve installed some Dell hosts with VMware vSphere 5.1 and used Dell Eq. PS6000 storage. To configure the connection between host and storage optimal I’ve used the Dell Equallogic Multipathing Extension witch is supported for vSphere 5.x
The SATP VMW_SATP_EQL is a VMware default one for EqualLogic arrays. And of course the PSP is DELL_PSP_EQL_ROUTED. The ‘ROUTED’ part refers ot DELL’s MEM being able to intelligently route I/O requests to the array path best suited to handle the request, to configure this with PowerCLI I’ve used the following code:
Get-VMHost HOST | Install-VMHostPatch -HostPath "/vmfs/volumes/VMFS-009-SSD/dell-eql-mem-esx5-1.1.1.270268/metadata.zip"
Result:
The DELL_PSP_EQL_ROUTED is configured automatically and the path selection is selected

Last week I was configuring some new vSphere 5.1 (Enterprise) hosts in a dedicated cluster and created some VMFS 5.58 datastores at the Dell Eq. PS6000 SAN with latest firmware, after configuring SIOC I received this error message:
The datastore is connected to one or more pre-4.1 hosts that do not support Storage I/O Control.
That’s weird, I’ve reinstalled all hosts (not updated) and created new datastores, there are no vSphere 4.1 hosts in this cluster (even connected to the datastore) and the PS6000 supports SIOC..
Solution:
Not really a solution.. but you can only configure SIOC with the Enterprise Plus license.. crap!

VMware vSphere ESXi 5.1 was released last month, after upgrading my hosts I had some really annoying issue’s, I couldn’t connect my iSCSI (QNAP) datastores and the hosts failed with a PSOD.. once I checked the HCL at the VMware website I saw that my HP DL360 G5 isn’t supported anymore.. time to rollback the latest installation.
Solution:
(Re)boot the host and press R to start the Recovery Mode..
Installed hypervisors:
HYPERVISOR1: 5.0.0-623860
HYPERVISOR2: 5.1.0-799733 (Default)CURRENT DEFAULT HYPERVISOR WILL BE REPLACED PERMANENTLY
DO YOU REALLY WANT TO ROLL BACK?
Press Y to start the roll back
Result:
The host is downgraded and back online again with VMware vSphere ESXi 5.0.0

During upgrade my HP DL360 G5 ESXi 5.0 u1 hosts to ESXi 5.1 I received a purple screen with warning message:
The system has found a problem on your machine and cannot continue.
VMware ESXi requires the Execute Disable/No Execute CPU feature to be enabled
Solution:
Restart the host, press F9 to boot in BIOS mode
Advanced Options > Processor Options > No-Execute Memory Protection, then configure: Enabled
