Figure 1. Example of Switch Zoning on SAN on an MD38xxf-series Fibre-Channel Storage Array World Wide Name Zoning There are several different switch zoning techniques used across various SANs. When configuring zoning with your storage array, using a 64 bit World Wide Name (WWN) to uniquely identify each component in your Fibre Channel switch fabric[...]

together, the switch allows the host server to see only devices included in that zone, decreasing the amount of time it would otherwise take for the host server to query attached, but out-of-zone, devices. Switch Zoning Guidelines The storage array imposes specific requirements that must be followed when setting up Fibre Channel switch zoning: • [...]

the host server(s) from losing access to data in the event of a path failure since both RAID controller modules can independently access all the physical disks in the storage array. SAN-Attached Cabling SAN-attached cabling configurations provide the highest level of redundancy and alternate-path connectivity between the host server and storage arr[...]

6 Load Balancing Load Balance Policy Multi-path drivers select the I/O path to a virtual disk through a specific RAID controller module. When the multi-path driver receives a new I/O to process, the driver tries to find a path to the current RAID controller module that owns the virtual disk. If the path to the current RAID controller module that ow[...]

If more than one data path to the virtual disk has the same weight value, the round robin with subset path selection policy is used to route I/O requests between the paths with the same weight value. The least path weight load balance policy is not supported on Linux operating systems. Setting Load Balance Policies in Linux Linux only supports roun[...]

7 Appendix — Working With SFP Modules And Fiber Optic Cables Each storage controller can have up to four FC host ports. A small-form-factor pluggable (SFP) module is used to connect a host port to a host or switch. The SFP module is inserted into the port, and then a fiber optic cable is inserted into the SFP module. The other end of the fiber op[...]

Labeling Cables Cabling is an important part of creating a robust storage array. Labeling the cables identifies system components and drive channels. System maintenance is easier when the cables are correctly identified. Label both ends of each cable. You can use adhesive office labels that are folded in half over the ends of each cable. Mark the l[...]
