What is the SAN (Storage Area Network)?
Understanding the ISCSI Switch
When we need to build our SANs or iSCSI network, we usually heard of DELL iSCSI switch, HP iSCSI switch and so on. However, what is the iSCSI switch? The iSCSI switch is a device that processes and channels data between the iSCSI initiator and the target on a storage device. ISCSI traffic is usually high speed and high capacity, and it needs to be provided with minimal delay. Unlike dedicated FC SAN switches, iSCSI switches are standard Ethernet network switches and can be used for iSCSI traffic optimization. ISCSI switches provide reliability while enhancing network control and supporting quality of service.
The Reason Why Choose 10G ISCSI Switches for SAN
- Flow control: building the SAN by using 10G iSCSI switches can help the host avoid being overwhelmed by the high traffic associated with iSCSI storage through allowing the host to control the rate at which data is received, and use flow control. Traffic control can also help prevent packet loss and avoid increased delays in iSCSI storage networks.
- Jumbo frame: the high payload of jumbo frames can be processed by providing fewer frames to the switch, thereby improving the efficiency of data transmission. This can improve 10G iSCSI performance, but using jumbo frames may cost more. Basically, the better the iSCSI switch is, the better your SAN will be.
- Link aggregation: also known as port trunking, this feature combines switch ports into higher bandwidth trunks to increase throughput and create redundancy. This is significant for you to build your SAN.
