NTER ANY PROBLEMS WITH THE HBA THE FIRST STEP IN THE DEBUGGING PROCESS IS VERIFYING THAT YOU ARE USING THE LATEST DRIVER AND FIRMWARE The speed of the server and network interface ultimately limit the RamSan 500 s capabilities A few different components can affect the maximum performance of the RamSan 500 including FC interfaces Host Bus Adapters PCI buses and server CPU resources 3 1 1 Fibre Channel Interface Currently the RamSan supports two Fibre Channel communication speeds 2 and 4 gigabit Accounting for encoding and overhead these transfer rates allow data to be transmitted to the RamSan 500 at a half duplex rate of 200 MB s and 400 MB s for 2 and 4 gigabit respectively Fibre Channel interfaces have separate read and write connections that allow a maximum data rate of twice the half duplex rate To sustain the maximum full duplex rate the data usage pattern of the system must be 50 read and 50 write due to the individual half duplex limits To find the maximum for other data usage patterns use the following formula 4 gigabit HBA Smaller usage percentage Larger x 400MB s 400MB s For example to calculate a data usage pattern with 66 reads and 33 writes 33 66 x 400 400 600 MB s Many applications require storage bandwidth that exceeds what a single FC connection can provide To accommodate this situation we provide up to 8 FC ports per RamSan 500 each of which can supply the bandwidth d
