Err, no. SGIs were first very expensive (3D) graphics workstations and later mostly also-rans in some other markets like storage and general-purpose big servers.
Servers were Sun, x86, HP-PA, IBM R6000 RISC (and probably some more UNIX / RISC systems). Workstations were PC, Sun, Apple (mostly for graphics / design), some NeXT.
