P4000 VSA (ESX) node high CPU usage
Software version is 9.0.00.3561.0 and is running on ESX 4.0 U2.
If you need more details I wil be more than happy to provide.
Thanks

Re: P4000 VSA (ESX) node high CPU usage
Can you confirm if your utalisation is on the host or the VM. If so what physical CPU's do you have in your host?
I feel that the VSA needs a second vCPU to avoid this issue but I dont think adding a second vCPU is supported

Re: P4000 VSA (ESX) node high CPU usage
2 Core would be fine.
VMware VAAI vStorage offloads
HP StorageWorks SAN/iQ software version 9.0 includes support for VMware ESX 4.1 and higher to offload tasks to the storage to improve efficiency and speed of specific workloads:
Deploying templates, cloning, and storage VMotion are offloaded to the array
Creation of large virtual disks for use with Fault Tolerance (block zeroing) offloaded to the array
Volume and LUN locking is enhanced to allow more virtual machines to share the same volume without affecting performance

Re: P4000 VSA (ESX) node high CPU usage
Multiple cores, that sounds interesting.
VMKB1010184 - Setting the number of cores per CPU in a virtual machine
http://kb.vmware.com/kb/1010184
If I remember correctly, it is 'supported' beginning with ESX 4.1, but was already built into 4.0

Re: P4000 VSA (ESX) node high CPU usage
Host CPU model is Intel Xeon E5420.
Didn't use more CPU's because of a post to this forum explaining that multiple CPU's can cause a lot of problems, especially during the boot.
I can try adding more cores, but as Uwe Zessin said we are using ESX 4.0 U2 which is not supported at the moment.
Please let me know if there is another way to sort this issue, maybe some protection mechanism of some sort?

Re: P4000 VSA (ESX) node high CPU usage
I thought the multiple core config was really a licensing fudge for apps there were licensed by socket.
For this to work The San iq kernel would need to support smb processing. I did read some people had thus working in 8.5 but then couldn't upgrade to 9.0
This is a production environment and must be supported config.
I am surprised there are not more complaints about this since 9.0 and the introduction of VAAI. We may have to look at disabling this feature as currently we have to be very careful when doing anything that uses VAAI as it swamps the single vCPU - not much if a step forward
I am assuming the physical appliances make use of multiple cores so why not document and allow the same on the VSA
Anyone from HP got any ideas?

Re: P4000 VSA (ESX) node high CPU usage
The VSA itself is optimised for older CPU types with less cores and higher speed (MHz).
What I have discovered is that in some documents the minimum CPU resource reservation recommended is 2000MHz and in other 4000MHz.
For example our physical CPU is Intel Xeon E5420 with 2.49GHz speed, which means that there is no way to reserve more than 2.49GHz which is lower than recommended minimum.
That explains why we are experiencing issues.
With the new CPU's on the market with even lower MHz per core this problem will even worsen.
Our new ESX server has Intel Xeon E7540 with only 2GHz speed.
I hope that HP will find a way to support more than one vCPU, our entire infrastructure is on the VSA SAN now.

Re: P4000 VSA (ESX) node high CPU usage
At the end of the day SANIQ is just software and I doubt they have restricted the physical appliances to use a single core.
People have added second vCPU's in the past but then they were unable to upgrade to V9.
In the past I don├в t think the single vCPU would have been much of a show stopper. But now 10Gb networks are more common and technologies like VAAI allow tasks to be offloaded direct to the SAN I really think HP need to rethink this strategy ASAP and provide a supported method of adding a second vCPU
I am still waiting for our paper licenses to arrive and direct support with HP. They should be here next week so I will log a call with HP, as it seems they don├в t really monitor these forums. But if anyone gets a chance to log a call before then it would be greatly appreciated.

Re: P4000 VSA (ESX) node high CPU usage
life is never easy. Finally got our 10 node VSA license through. Now trying to get a SAID number generated to log a call.
I take it no one has had any joy with increasing the CPU count?

Re: P4000 VSA (ESX) node high CPU usage
Any update on this? Maybe new P4000 version brewing?
