I have a Dell Power Connect 6224 as my Server Rack Switch. According to dell it has a Switch Fabric Capacity of 136Gbps and a Forwarding Rate of 95mpps.
Currently when I'm running a bandwidth test to my Dell MD3000 iSCSI San i'm only get about 250mbit\s (megabits).
Now i know there could be a 100 reasons for his, however this is what i know:
Using CAT6 Cabling
Jumbo Frames enabled on both Server, Workstation and in Switch
All machines show full duplex 1000
Workstation Disk Checks show the capacity to write at 250MB\s (MegaBYTES)
Server Disk Check show the capacity to write at 2000MB\s (megaBYTES)
Cable test shows both CAT6 cables are good.
Now why am I only seeing a network read\write speed of 250mbps (megabits) In the past I have seen higher, but one would think when writing to my file server even with the overhead of windows i should be above 500mbps.
