Integrating Dell PowerVaultTM MD3600i/MD3620i Arrays with Existing SANs Performance of MD36x0i The MD36x0i series of arrays were designed with performance in mind. Each controller is equipped with two 10GbT Ethernet ports providing total aggregated theoretical bandwidth of 4000MB/s per array. In Figure 1, for sequential read applications under base mode (default settings), we can see that MD36x0i with 4 x 10GbT Ethernet ports performs 4 times better than MD3000i with 4 x 1GbT ports. Also, MD36x0i performs 1.5 times better than MD32x0i with 8 x 1GbT ports. MB/s SEQUENTIAL READ (MB/s) 1600 1400 1200 1000 800 3000i 3200i 3600i 600 400 200 0 Packet Size Figure 1. Comparison of MD3000i, MD3200i and MD3600i performance for Sequential Reads in Base Mode For sequential write (Figure 2), random read (Figure 3) and random write (Figure 4) applications, under base mode (default settings), MD36x0i with 4 x 10GbT Ethernet ports performs almost twice as well as MD3000i. Also, MD36x0i with only 4 x 10GbT ports performs as well as MD32x0i with 8 x 1GbT ports. Page 4
