HPSS uses raw SCSI block storage for disk cache. HPSS movers perform all IO to SAN or direct-attached flash and spinning-disk technologies. Deploy mover-computers and storage-hardware to scale bandwidth and capacity as needed.
Types of Storage
HPSS Metadata
High IOPS and high bandwidth storage like NVMe flash is best for HPSS Db2 metadata storage.
HPSS Disk Cache
Deploy a mix of flash and spinning disk storage units from DDN, NetApp, IBM, and similar for active data demanding low latency access.
HPSS Tape Libraries
Use a mix of IBM, Oracle, Quantum, and Spectra Logic tape libraries to reduce the total cost of ownership of your inactive data.
HPSS Tape Drives
Choose LTO drives for infrequently accessed cold-data, and Enterprise drives for active archive requirements.
Disk Cache Storage
Economical at Scale
The licensing model for HPSS is not related to the amount of data or the amount of hardware. HPSS software for 10 petabytes of disk or 100 petabytes of disk is the same. Thus, HPSS is incredibly economical at scale compared to storage software that is priced and licensed by capacity.

High-Performance Transfers
HPSS maximizes disk transfers by leveraging multiple threads per transfer.
Example: one-thread only delivers 1,305 MB/s, so HPSS is configured to automatically use eight-threads to saturate this 4,000 MB/s device.
Today’s savvy customers demand extreme-scale, high-performance transfers.
