Glossary SSP See system services processor. state The state of the Switch or Director. Possible values include online, offline, testing, and faulty. See also offline state; online state static random access memory SRAM. SRAM is microprocessor-cache random access memory. It is built internal to the microprocessor or on external chips. SRAM is fast, but relatively expensive (D). Contrast with dynamic random access memory. storage area network SAN. A high-performance data communications environment that interconnects computing and storage resources so that the resources can be effectively shared and consolidated. See also local area network; wide area network. stored addresses In S/390 mode, a method for configuring addresses. subnet A portion of a network that shares a common address component. On transmission control protocol/Internet protocol (TCP/IP) networks, subnets are defined as all devices whose IP addresses have the same prefix. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet mask. subnet mask A mask used by a computer to determine whether another computer with which it needs to communicate is located on a local or remote network. The network mask depends upon the class of networks to which the computer is connecting. The mask indicates which digits to look at in a longer network address and allows the router to avoid handling the entire address. Subnet masking allows routers to move the packets more quickly. Typically, a subnet may represent all the machines at one geographic location, in one building, or on the same local area network. switch A device that connects, filters and forwards packets between local area network (LAN) segments or storage area network (SAN) nodes or devices. switched mode If the arbitrated loop device is in switched mode, each pair of communicating ports on the arbitrated loop device can share the 100MB bandwidth. In switched mode, up to three pairs of loop devices can communicate with each other simultaneously. Or, a public device on the loop can communicate with another device on the fabric while up to two pairs of loop devices can communicate simultaneously. embedded web server user guide Glossary-35
