Extreme Slow Replication on HP Hardware

[Manfred]

Anybody using Replication with HP Hardware?

Hi,

i had the same issue with 2 StorageWorks X1600 from HP (looks like DL185G5). Also very slow replication over LAN. All other seems to work well.

Had anybody solved this problem?

I'am in contact with OPEN-E Support. They didn't really solved the Problem yet, but one of the
OPEN-E Support Guy's improved the Performance up to 20 MB/Sec on my Lab Systems.
Probably there ist a Problem with the DRDB Configuration.

The OEPN-E Support Statement is: we are working.....

I'am in upbeat mood!

Hi there,

Did you get this resolved?

Thanks,

Hi,

OPEN-E Support solved the Problem not yet. They promised me a Patch for the coming Version.

BUT - using Intel Dualhead 82571EB (rev 06) NIC for Replication works in another Configuration
very well (40MB/Sec) for Syncronisation.

So, may bei the Broadcom and/or older Intel Gigabit NIC's causing Problems.

Yes I am using HP DL180 G6's with Replication I was getting 600Kb/s replication speeds. Open-e Support had to remote into our DSS servers and tweak settings to get them to replicate at 60MB/s.

We are now looking at getting new RAID cards, as the HP Storageworks P212's are useless.

Are there any details on what was done to achieve this faster speed? We have a similar situation with a couple of HP DL360's with MSA arrays, not getting as much throughput on the sync NIC's as I would expect, used both onboard and NC360T dual cards with similar results.

you can tune the drdb.
search this forum for info on how.
