TECH CORNER

compression makes it ideal for
bulk data storage.
Clients often use DFSMShsm
to migrate data to different storage
tiers and back up their data.
Disk space savings from zEDC
compression can be valuable
when DFSMShsm migrates or
backs up data to a disk tier.
When DFSMShsm migrates data
to tape, zEDC compression isn’t
necessary because tapes have
their own hardware-based,
built-in transparent compression.

DFSMShsm is planned to provide
zEDC compression support in
Q3 2014.

Compression Futures
Compression is a powerful tool for
reducing the cost of transmitting,
storing and processing data.
Hardware acceleration of
compression algorithms in the
host and in storage devices
can provide reduced storage
costs and improved throughput
compared to existing software

approaches. The emergence of
a new class of adapter-based
compression hardware operating
independently from the CPU
opens new opportunities for
compression throughout the
storage hierarchy. Delivering
compression rates greater than
1 GB per second, supporting
industry standards and using very
little CPU, zEDC Express eases
the tasks of storing, transferring
and archiving ever-increasing
amounts of sequential data.

What Makes up a zEDC Express Compression Accelerator?
zEnterprise* Data Compression (zEDC) Express does high-performance,
industry-standard compression using the Deflate algorithm. The zEDC
Express card is an I/O adapter similar to a cryptographic adapter
available for the zEnterprise EC12 (zEC12) and zEnterprise BC12
(zBC12) servers. Up to eight zEDC Express adapters can be installed in
a single machine. Each can be shared by up to 15 LPARs and consumes
very little power per byte of compressed data.

Building an I/O Adapter That Does Compression
Most general-purpose data processors are optimized to act on
character strings and numbers. Compression acts at a lower level,
the bit level. zEDC Express gets its enormous throughput and
power efficiency by using dedicated compression hardware directly
optimized for the Deflate compression algorithm.

Integrating zEDC Express Into the zEC12
and zBC12 Servers
zEDC Express meets the special needs of System z* servers,
such as:

1

Continuous availability.
Configuring two zEDC
Express adapters to
a z/OS* partition can maintain
continuous access to
compression services over the
loss of an adapter and over
firmware updates. Configuring
four adapters per partition
leaves no single point of failure,
even over firmware updates.

2

Data Integrity. Data
integrity checking is
integrated into the compression
engine. All compressed data is
decompressed and compared
to the original data to ensure
correct operation.

3

Error detection and
reporting. The zEDC Express
adapter self-checks and is
monitored by the server. Failures
are isolated and reported.

4

Sharing. Adapters are
sharable across up to 15
partitions with fair access from
each partition and total data
isolation between partitions.
Sharing allows individuals to use
only four zEDC Express adapters
to meet production throughput
and requirements for test and
assurance configurations.

5

Dynamic Reconfiguration.
Adapters can be added to
and deleted from LPAR partitions
on the fly. A z/OS compression
service routine handles workload
balancing across available zEDC
Express adapters.

6

Future-Proofing. Adapters
are isolated from exploiters
through the z/OS service routine.
Over time, new approaches to
compression will emerge. The
system architecture is intended
to allow a transparent intermix
of zEDC Express adapters and
future compression hardware.
