DEC built a whole series of HSC controllers beginning with the HSC50 and ending with the HSC95.
See the following table for characteristics and upgradability of the HSC models:

HSC Channel Interfaces
A Channel is a pluggable HSC interface to either hard drives, tape drives, or both, depending on the channel module. The number of devices that can be connected also depends on the channel module.
HSC controllers may contain a mix of the following data channel module options:
- HSC5X-BA (L0108-YA) K.SDI INTERFACE KIT TO 4 SDI DISK DRIVES
- HSC5X-CA (L0108-YB) K.STI INTERFACE KIT TO 4 STI TAPE FORMATTERS
- HSC5X-LA (?) HSC5X-BA WITH SUPPORT FOR TOPS-10/20 (18 BIT)
- HSC5X-DA (L0119-YA) K.SI INTERFACE KIT TO 4 SDI DISK DRIVES OR 4 STI TAPE FORMATTERS
- HSC5X-FA (L0119-YB) 8-PORT DISK DATA CHANNEL DISK/TAPE DATA CHANNEL (not supported by HSC50, HSC70, and HSC40)
- HSC9X-SX (L0131-AA) K.SCSI SCSI DISK DATA CHANNEL (not supported by HSC50)

1) The HSC60–AA/AB/BA/BB without the cache option does not have an auxiliary power supply. The HSC60–AA/AB/BA/BB with the cache option has the auxiliary power supply installed. The auxiliary power supply is supplied as part of the HSC6X-BA/BB cache option installation kit.
2) If the HSC50 has four or more requestors, it requires an auxiliary power supply.
