Testing Scenarios and Results

Scenario 6—Impact of Compression on CPE (Cisco 9216i) Performance

You can compress the data stream to reduce WAN link utilization. Some WAN deployments may require compression to obtain adequate throughput. For example, with a 2 to 1 compression ratio, you can obtain 90 Mb/sec of storage data throughput over a 45-Mb/sec DS3 WAN connection. You may also need encryption to protect the confidentiality and integrity of the storage data stream.

Figure 4-17shows the MDS FCIP and compression latency.

Another variable that affects compression performance is the IP MTU size on the FCIP connection. SAN Extension data packets are usually the maximum Fibre Channel size of 2148 bytes. With an IP MTU of 1500 bytes, the IPS must fragment large Fibre Channel frames into two IP frames, which decreases overall performance. Also, the data compression occurs after the Fibre Channel frame is encapsulated into IP, and compression works better with a larger frame to examine. Therefore, the use of IP jumbo frames is recommended for IPS FCIP connections if the network can support it. This increases the efficiency of both Fibre Channel frame encapsulation and data compression.

Figure 4-18shows the different compression ratio of IPS and MPS as compared to other modules.
