HSV100 & HSC200 internals/components

I currently have an EVA3000 with a pair of HSV100 controllers and an EVA4000 with HSV200's.

I am trying to find a document which lists the details of controller devices. for example:

Is there a processor in the controllers similar to how EMC CX4 SAN has Intel Xeon processor in its storage processor enclosure?

How much Cache is installed per controller?

How much write cache is installed per controller?

How much memory if any is installed in each controller?

I need to compare my current EVA performance to an EMC CX4 SAN in order to decide which technology we move forward with. Any advice on this subject will also be helpful.

Re: HSV100 & HSC200 internals/components

3000 = ???
4000 = PowerPC, don't know the speed

How much Cache is installed per controller?
3000 = 2GB/controller pair
4000 = 2GB/controller pair

How much write cache is installed per controller?
Both use part of the cache for both reads and writes. It is a moving percentage based on the workload.

How much memory if any is installed in each controller?
Not sure what you mean here. I believe it is the same answer as #2.

As for advice, I would not just the above numbers in a table and choose the one with the biggest amount of cache or fastest processor. Different arrays handle workloads differently. A lot of time goes into caching algorithms, handling spikes in workloads, failures of components within the array, and many more. If you can get a demo from both vendors, that would be your best way to test your needs. Just make sure your tests are reflective of your typical production workloads.

Good Luck,
