OC950 Hardware
Varieties
Two optional memory (NVRAM: nonvolatile random access
memory) configurations are available, 32kx8 or 128kx8. NVRAM
is battery backed, with a ten year life, and unlimited amount of
write cycles. The memory provides storage for the user programs.
A PacLAN Network interface is offered as an OC950 option.
PacLAN supports 2.5 Mb/sec communications between a cluster
of SC950 drives. The port will be compatible with standard
ArcNET products using 93 Ω coax cable in a bus configuration.
