is a senior technical
staff member and
chief engineer of
an I/O subsystem
development team
within IBM Systems
and Technology
Group.

Called Flash Express, this
feature is implemented with PCI
Express (PCIe) adapters containing
SSDs configured in RAID 10 arrays
across cable-connected pairs in
I/O expansion drawers. The initial
exploitation of Flash Express is
as an extension to main memory
in z/OS* where it's integrated
within the memory hierarchy and
administered by the z/OS memory
manager to provide increased
system availability and resiliency
during paging-intensive events.

Benefits of
Flash Express
Server installations are being
pressured to deliver increasingly
higher levels of availability in
nearly every industry-especially
finance, banking and healthcare.
With Flash Express, the system
can reduce workload and
response-time delays caused
by increased memory pressure
during periods of peak demand,
transitions between workloads or
diagnostic collection.

For example, when transitioning
from a transactional workload
during a prime shift to a batch
workload, and then back again
during the next prime shift,
response-time delays can occur.
The system can reduce these delays
by using Flash Express when
data for the prime shift must be
transferred from auxiliary storage
into main memory. Flash can
also help when the system must
transfer data into main memory
as part of a diagnostic dump. The

or the first time, flash storage has been integrated into IBM System z*
servers. This new function brings an enhanced client experience on
enterprise applications by providing additional auxiliary storage with
higher performance than external disks.
