The VAXft Model 110, code named "Cirrus", was an entry-level model announced on 18 March 1991 alongside three other models. The Model 110 was essentially a low-cost model of the VAXft Model 310, and had a theoretical maximum performance of 2.4 VUPs.
It contained two zones packed side by side in an enclosure. Compared to the Model 310, it was limited in expandability in regards to memory, storage capacity and available options. It was available in either a pedestal or rackmount configuration. The rackmount configuration was a pedestal without the plastic covers or casters that fitted in a standard 19-inch RETMA cabinet.
Each zone had a five-slot backplane for a KA510 CPU module, one to three 32 MB MS520 memory modules, one or two KFE52 system I/O controller modules and one or two DEC WANcontroller 620 (DSF32) wide area network (WAN) communications adapters. The leftmost slot was the first slot. The primary system controller resided in the first slot, the CPU module in the second, and the memory modules in the third, fourth and fifth slots. The second system I/O controller resided in either the fourth and fifth slots and the WAN communications adapters also in the fourth and fifth slots. The most basic system contained a CPU module, a memory module and a system I/O controller.
The DEC WANcontroller 620 was designed for use in VAXft systems. It provided two synchronous lines, each with a bandwidth of 64 KB. The lines could be operated as two independent lines or paired to provide redundancy.

Famous quotes containing the word model:
“The striking point about our model family is not simply the compete-compete, consume-consume style of life it urges us to follow.... The striking point, in the face of all the propaganda, is how few Americans actually live this way.”
—Louise Kapp Howe (b. 1934)
