Performance Lefthand VSA against Lefthand P4000

[mclmicha_1]

Hi all,

does anybody has experiences belonging the performance of a Lefthand VSA against a Lefthand P4000.
If taking the same HW with the same qty of drives but with ESXi and Lefthand VSA. No other VM is on the system, just the VSA. Of course it will be slower, but how much slower.

Thanks for answering.

Regards

Hello Michael,

hard to say. It depends on so many things. Sure a VSA can be faster then a P4000, especially if you have fast backend-storage.

In you case I would think about 5% or 10% overhead for virtualization.

Best regards,
Patrick

I just got out of a LHN Training class. If i read the note correctly, the VSA performs @90% under SAN/iQ running on physical hardware (A P4000)... so about a 10% hit.

Hi Patrik, hi Steven,

thanks for your answers.

Just a unterstanding question to you Steven.
Do you mean the VSA has 90% of the P4000 performance or do you mean the VSA has (only) 10% of the P4000 performane.

If you means second I can't understand that HP wants so much money for the VSA.

the VSA has 90% of the P4000 performance

By "10% hit" he meant overhead.

Uwe,

thanks for helping in understanding and once again thanks the others for help.

I'd expand on that a little bit.
Agree with the 90% when it comes to small IO, random IOPS like databases.
But when it comes to sequential workload, like file copies, cloning, backups, streaming, etc.
More like the VSA is only 60 to 70% as good as physical platforms made out of simliar hardware.
It comes down to the virtual network the VSA is hooked up to being significantly less performance and load balanced.

That is why some have been able to build some fast VSA though too, they put a lot of effort into making a really good virtual network.
