PowerStore systems support Ethernet connectivity through ports on the embedded module and optional I/O modules. FC connectivity is supported through ports on optional I/O modules. On PowerStore 1000 through PowerStore 9200 models, the I/O module in Slot 0 is 16-lane PCIe Gen3, while the I/O module in Slot 1 is 8-lane. Accordingly, if the system is configured with a 100 GbE I/O module, Slot 0 is preferred for installation. Both of the I/O modules on PowerStore 500 models are 8-lane PCIe. The 100 GbE I/O module is not supported on these models.
PowerStore FC ports
PowerStore FC ports support speeds of 32 Gb/s, 16 Gb/s, 8 Gb/s, and 4 Gb/s. This speed depends on the SFP that is used and the switchport or HBA that is connected. Because higher speeds allow for greater MBPS and IOPS capabilities, use the highest speeds that the environment supports. FC ports are available on I/O modules that are inserted into I/O module slots on the nodes. The FC I/O module is 16-lane PCIe Gen3. On PowerStore 1000 through 9200 models, the I/O module Slot 0 is also 16-lane, while I/O module Slot 1 is 8-lane. If you install FC I/O modules in both I/O module slots, cable the ports in I/O module Slot 0 first because of the PCIe difference. The PCIe lanes in I/O module Slot 1 are a limiting factor only for total MBPS and only when all four ports on the FC I/O module are operating at 32 Gb/s. Both I/O module slots on PowerStore 500 are 8-lane PCIe, and therefore there is no slot preference.
PowerStore Ethernet ports
PowerStore optical Ethernet ports support speeds of up to 25 Gb/s based on the SFP that is used. Copper Ethernet ports support speeds of up to 10 Gb/s. Because higher speeds allow for greater MBPS and IOPS capabilities, use the highest speed that is supported by your environment. A two-port Ethernet card has been introduced that supports speeds of up to 100 Gb/s. This 100 GbE card is supported on PowerStore 1000 to 9200 models in I/O module slot 0. Jumbo frames with an MTU of 9000 are recommended for increased network efficiency and must be supported on all parts of the network between PowerStore and the host. To improve network performance and redundancy, use bonded ports for NAS connectivity. For highest performance and availability from any aggregated ports, configure link aggregation across the corresponding switch ports.
