Easy Tier
Easy Tier is an optional feature that offers enhanced capabilities through
features such as auto-rebalancing, hot spot management, rank
depopulation, and manual volume migration.
Easy Tier enables the DS8882F system to automatically balance I/O access
to drives to avoid hot spots on arrays.
Easy Tier can benefit homogeneous drive pools because it can move data
away from over-utilized arrays to under-utilized arrays to eliminate hot
spots and peaks in drive response times.
z-synergy
The DS8882F storage system can work in cooperation with IBM Z hosts to
provide the following performance enhancement functions.
v Extended Address Volumes
v
High Performance FICON for IBM Z
v I/O Priority Manager with z/OS Workload Manager
v Parallel Access Volumes and HyperPAV (also referred to as aliases)
v Quick initialization for IBM Z
v Transparent cloud tiering
Copy Services
The DS8882F storage system supports a wide variety of Copy Service
functions, including Remote Mirror, Remote Copy, and Point-in-Time
functions. The following includes key Copy Service functions:
v
FlashCopy
v Remote Pair FlashCopy (Preserve Mirror)
v Safeguarded Copy
v Remote Mirror and Copy:
– Metro Mirror
– Global Copy
– Global Mirror
– Metro/Global Mirror
– Multiple Target PPRC
– z/OS Global Mirror
– z/OS Metro/Global Mirror
Multitenancy support (resource groups)
Resource groups provide additional policy-based limitations. Resource
groups, together with the inherent volume addressing limitations, support
secure partitioning of Copy Services resources between user-defined
partitions. The process of specifying the appropriate limitations is
performed by an administrator using resource groups functions. DS CLI
support is available for resource groups functions.
Multitenancy can be supported in certain environments without the use of
resource groups, if the following constraints are met:
v Either Copy Services functions are disabled on all DS8000 systems that
share the same SAN (local and remote sites) or the landlord configures
the operating system environment on all hosts (or host LPARs) attached
to a SAN, which has one or more DS8000 systems, so that no tenant can
issue Copy Services commands.
