Dear All,Is it True That EVA 4400 has a new firmware to deal with Replication Problems?
because till now we have a problem with replication and HP partner said there is a firmware but it's not official yet!!!

If you are having specific issues, you can call HP Support and request getting the latest version that is not "officially" available on the internet as of yet..

What firmware are the EVA's at now?

Can you describe the connectivity between the EVA's? (SAN Switches, Distance between sites, etc)

Dear
I don't know what firmware that will solve this problem because it's not official yet,this news I got it from HP Partner in Yemen

The distance between sites 35 km ,the bandwidth is 8 MBPS E1,connectivity normal as any storage

Our problem are
1- data replication operation is very very slow every 12 hours just 1%
2- Database activity also very slow

so,they said that firmware will solve these problems

What version of firmware is currently on your EVA's?


What hardware are you using to connect the sites? IP Distance Gateways? MPR's? something else?

1) Firmware 09534000 is mandatory on all EVAs that are using or have used Continuous Access

2) It's a final firmware version, just not released through the public web.

3) It contains fixes for Continuous Access but not for your case. For performance problems you must check PING latency on the replication link, and the buffer to buffer credits on the switches. There are parameters on the ports of the switches that have to be changed. See the Continuous Access planning guide.

8MBPS E1 - is that 8 megabit per second (roughly 1 megabyte per second?)

How much data is it trying to replicate?

I would definately check out the utilization of the link. Check out the evaperf utility for checking utilization/performance of the EVA

It's not public yet so doubt that should be shared here. If you want a more detailed description of what it fixes you should probably contact HP support.
