Epoch Systems Inc’s recently previewed Epoch-1 data storage server, which is said to integrate magnetic and optical disk technology for application-transparent on-line storage, can provide up to 150Gb of memory, and is aimed the technical workstation market. One to three 700Mb Winchester disk drives are backed up by an Optical Disk Library Unit, a jukebox containing optical disk cartridges and four optical disk drives. The idea is to keep active files on the front-end Winchester drives, and move others on to the optical devices. Conversely, files can be lifted out of the optical jukebox and transferred to magnetic disks when required. Epoch-1 comes in three versions. Model 2 has two 700Mb magnetic disk drives and a 600Mb optical disk drive, costing $95,000. The Model 30, again with 700Mb magnetic – but 28.8 Gb optical – is priced at $155,000. Top of the line Model 150 comes with a 700Mb magnetic drive and five 28.8Gb optical disks – a total of 150Gb – for $450,000. Epoch Systems is headquartered in Marlborough, Massachusetts.
