WAAS 5.3.1 support iSCSI?

[netstaradam]

Hi, We have 3 units WAE294 and 1 for CM another 2 are located on central site and DR site for our V5000 storage data replication..

Does WAAS 5.3.1 is support iSCSI traffic? need special setting?

Hi Adam,

If you look at the predefined application policies here : http://www.cisco.com/c/en/us/td/docs/app_ntwk_services/waas/waas/v551/configuration/guide/cnfg/apx_apps.html

You'll find that iSCSI traffic on TCP port 3260 is TFO, DRE & LZ optimized.

So no special setting is required, if you run with the default policy.

Hi Finn,

Thanks answer..

But Between Central and DR the V5000 storage replication about 800GB.

We use WAAS 5.3 (WAE294) on both sites and default policy, wan bandwidth is 2Mbps.

The V5000 display disconnect once every hour.

Should I downgrade to 4.0.19 to use Replication Mode?

Best Regards,

Hi Adam,

WAE294 (or actually WAVE294) requires WAAS version 4.4 and later, so 4.0.19 is a nogo.

And to be honest I don't think replication mode would have helped you, basically it's just another way of carving the ressources on the WAE box.

You'll have to investigate, why it disconnects.

Does the traffic gets optimized ?

But it's a lot of traffic to transfer across a 2 Mbps line, unoptimized it would take around 900 hours, with minimal delay to transfer 800GB of data.

Does the replication ever finishes ? - Or is it a constant running task with only changes, so it's not a full transfer.

The WAVE-294 has around 55 MB of disk spaces set aside for DRE cache, so you'll have to look for cache eviction (age of DRE content).
