Re: Move WAE 512-K9 from T3 to OC3?

olsonc0510 · ‎06-13-2011

We purchased a WAAS device a few years back. The circuit it is on is going away. It was a T3. We want to move it to an OC3. That's quite a jump. I am wondering if it will be able to handle the increase it traffic. I don’t want it to end up being a bottleneck. What do you think?

Central manager is a WAE 612-K9

Application Accelerators on both sides are WAE 512-K9

All traffic is replication traffic between two sites.

Thanks,

I made a mistake. The two edge devices are 612. The Central Mgr. is a 512.

Hi,

WAE-612 with 4 GB can support upto 90 Mb WAN Bandwidth and 4800 Optimized TCP connections as per the sizing guidelines.

However, recommended WAN bandwidth is not limited in software or by any other system limit, but is rather provided as guidance for deployment sizing purposes. While sizing you also look at the number of TCP sessions in use.

In you case since these are optimizing only replication traffic (which I assume to be less number of connections) what is the maximum number of TCP sessions at any time you forsee with increased replication traffic.

Regards

Kiran

There are 3 separate connections for replication coming accross this circuit. I am unsure how many sessions that entails. I'll do some more digging. However, based on your statement, we could still probably get something out of these devices even though they are rated for less bandwidth.

We are moving our data center so this will only be temporary. I just didn't want to go through the process of moving the devices, only to find that they are hindering, and not helping the connection.
