Cartridge storage system has 175M byte capacity

Masstor Systems Corporation has introduced the M860 mass storage system, which is a large- capacity cartridge-based data storage device.

The M860 operates around its storage module, a honeycomb- like system of cells that holds 316 3.5~ data cartridges, each with a 175M-byte capacity. Thus, each module has a 55G- byte capacity; the unit's overall capacity in its fully redundant maximum configuration, which links eight storage modules to two storage controls, is 440G bytes. (Multiple M 860 systems can be attached to a single CPU, or can be shared among several CPUs, providing trillions of bytes of potential storage capacity.)

According to the company, the M860 provides 55 percent more storage capacitythan an entry- level IBM 3850 mass storage system.

With the M860, when a user requests a file, the storage- management software orders the storage control to activate the accessor in the module where the appropriate data cartridge is stored. The accessor removes the cartridge and transports it to a data recording device, which reads the information and transfers it through the storage control to the CPU channel. When the file has been processed, new or modified data is entered on a data cartridge, which is then returned to its resident cell. Data can be processed in tape mode directly or staged to a disk for processing.

The unit has a successful thread rate, without retry, of up to 99.8 percent, and uses a dynamic skew compensation system.

Optional features for redundancy and increased-performance include a second datarecording control and a dual data path within the storage control. Other optional features for redundancy against single points of failure are also available.

The M860 mass storage system will be available during the second quarter of 1982, and is priced from $450,000.

(Image Omitted: The TRS-80 PC-2 pocket computer has internal expansion capability with plug- in RAM and/or ROM modules, and external expansion capability through a 60-pin 1/O bus connector, The unit features a 16K (ROM) Extended Basic interpreter with 42 statements, 34 functions, and 6 commands. The PC-2 uses an 8-bit custom CMOS microprocessor with 16K of ROM and 2640 bytes of user memory. Memory is retained when power to the unit is turned off.
