Introduced in November of 1999, Sun's Netra t1 100 and t1 105 servers were Sun's first 1RU (rack-unit) servers. Offered with either the 360- or 440- MHz UltraSPARC-IIi, single processor, the systems could support up to 1GB RAM and 1 or two hot pluggable 9.1 GB or 18.2 GB UltraSCSI disk drives.
The Netra t1 100 was the DC version of the server and the t1 105 was the AC version of the server.
The t1 100 and t1 105 were EOL'd (end-of-lifed) in August 2002, and were superceded by the Netra T1 AC200.
