WAAS implementation queries

Unanswered Question
Jan 18th, 2008


We're looking to consolidate our IT infrastructure into our datacenter and are looking at the WAAS solution for WAN optimisation and app acceleration. I have a couple of queries that I can't easily find answers too.

1 I've found performance data for the NME-WAE-502-K9 (500 concurrent TCP connections and around 5 Mbps optimized traffic). However, I can't find relative performance data for the 512 and 612 WAEs. Does anyone have this info (real world stats would be ideal)? - A number of our remote sites have BW of 10Mbps and 100Mbps..

2 I'm still not clear on the features of the Central Manager license; I know that a CM is required within a WAAS solution. I'm looking at putting a pair of WAE-612s into the datacenter (100Mbps connection) and am not sure if I should have both with the CM license - Does the CM license include the functionality of the Enterprise (e.g. App acceleration, CIFS etc) or should I have one with CM and the other with Ent license and then will this work as redundant pair?

Thanks in advance..

I have this problem too.

1. The performance numbers for the 512 and 612 are as follows:

WAE-512-1G: 750 optimized connections, 8Mbps target WAN bandwidth

WAE-512-2G: 1,500 optimized connections, 20Mbps target WAN bandwidth

WAE-612-2G: 2,000 optimized connections, 45Mbps target WAN bandwidth

WAE-612-4G: 6,000 optimized connections, 90Mbps target WAN bandwidth

2. The Central Manager is used purely as management platform. It runs on a separate, dedicated WAE and does not perform any traffic acceleration functions.

Hi Zach,

Thanks for the response, could you pls answer a couple more questions?

1 As we have some sites with BW above 90Mbps can you pls let me know the rated performance of the 7236 & 7341 WAEs?

2 What are the constraints for the Central Manager WAE? i.e. can we run CM on a 512 if we have higher spec WAEs in the solution?

3 Can you run 2 x WAEs in a HA cluster (e.g. 2 x 7236s running Ent license)?

Thanks again..

Here are the responses to your questions:

1. WAE-7326 is no longer a recommended platform. The WAE-7341 should be used instead. The WAE-7341 is targeted for WAN bandwidth up to 310Mbps. In addition, the WAE-7371 is targeted for WAN bandwidth up to 1Gbps.

2. The number of WAEs that can be managed by a CM depends on the WAE model you are using for the CM. The current numbers are as following:

WAE-512-1GB = 500

WAE=512-2GB = 1,000

WAE-612-2GB = 2,000

WAE-612-4GB = 2,500

It does not matter what model WAEs are being managed.

3. Yes.
