15 HP Priority Optimization During recent years, consolidation of storage systems has reduced complexity of data storage, delivering efficiency in management, occupied floor space, and energy consumption. However, the consolidation of many disjoint workloads into a single storage system also results in contention for shared system resources on the system. Examples of such shared resources include front-end host Fiber Channel (FC), iSCSI and FCoE adapters, back-end FC or SAS disk connections, physical disks, data and control cache, ASICs, CPUs, and backplane interconnections. Data packets arriving at the front-end FC HBA adapters are handled on a first-come, first-serve basis. On the surface, this may sound fair, but it can lead to unequal and inconsistent throughput for multiple concurrent workloads. HP 3PAR's Priority Optimization software manages and distributes the I/O capacity of an HP 3PAR StoreServ Storage system across multiple workloads. The tool enables the co-location of the data of workloads of different types, such as sequential, random, online transaction processing (OLTP), with different I/O packet sizes on a single storage system while achieving adequate and stable performance in a multi-tenant environment. Requirements HP 3PAR Priority Optimization is supported on all HP 3PAR StoreServ Storage systems that are certified for HP 3PAR OS 3.1.2 MU2: • HP 3PAR StoreServ Storage F-Class • HP 3PAR StoreServ Storage T-Class • HP 3PAR StoreServ Storage 7000 • HP 3PAR StoreServ Storage 10000 A valid license for HP 3PAR Priority Optimization is required on the HP 3PAR StoreServ Storage system. The HP 3PAR Priority Optimization has its own license key. The license is spindle-based, available a-la-carte and as part of the Data Optimization Suite v2 available for HP 3PAR StorServ 7000 and HP 3PAR StorServ 10000 systems. Consult your HP representative or authorized HP partner for more information on HP 3PAR Priority Optimization licensing. Creating and managing QoS definitions requires the HP 3PAR MC 4.4 and later. To use the command line, you must install HP 3PAR CLI 3.1.2 MU2. Reports on HP 3PAR Priority Optimization are available through HP 3PAR System Reporter 3.1 MU1 and later, and through the HP 3PAR MC 4.4 and later. The reports on the QoS definitions require a license for HP 3PAR System Reporter. While QoS is in principle OS-agnostic, see the HP SPOCK website for the list of operating systems that are certified for use with HP 3PAR Priority Optimization: http://www.hp.com/storage/spock Virtual Volume Sets QoS rules operate on sets of VVs called VVsets. A VVset is an autonomic group object that is a collection of virtual volumes. VVsets help to simplify administration of volumes and reduce human error. An operation such as exporting a VVset to a host will export all member volumes of the VVset. Adding a volume to the VVset will export the new volume automatically to the host or host set. VVsets have a number of use cases beyond reducing administration for their volume members. Most HP 3PAR Remote Copy operations are performed on sets of virtual volumes called remote copy volume groups. VVsets also enable simultaneous point-in-time snapshots of all volumes contained in the set with a single command. Up to 8192 volumes can be part of a VVset. Requirements 147

15 HP Priority Optimization
During recent years, consolidation of storage systems has reduced complexity of data storage,
delivering efficiency in management, occupied floor space, and energy consumption. However,
the consolidation of many disjoint workloads into a single storage system also results in contention
for shared system resources on the system.
Examples of such shared resources include front-end host Fiber Channel (FC), iSCSI and FCoE
adapters, back-end FC or SAS disk connections, physical disks, data and control cache, ASICs,
CPUs, and backplane interconnections. Data packets arriving at the front-end FC HBA adapters
are handled on a first-come, first-serve basis. On the surface, this may sound fair, but it can lead
to unequal and inconsistent throughput for multiple concurrent workloads.
HP 3PAR’s Priority Optimization software manages and distributes the I/O capacity of an HP 3PAR
StoreServ Storage system across multiple workloads. The tool enables the co-location of the data
of workloads of different types, such as sequential, random, online transaction processing (OLTP),
with different I/O packet sizes on a single storage system while achieving adequate and stable
performance in a multi-tenant environment.
Requirements
HP 3PAR Priority Optimization is supported on all HP 3PAR StoreServ Storage systems that are
certified for HP 3PAR OS 3.1.2 MU2:
HP 3PAR StoreServ Storage F-Class
HP 3PAR StoreServ Storage T-Class
HP 3PAR StoreServ Storage 7000
HP 3PAR StoreServ Storage 10000
A valid license for HP 3PAR Priority Optimization is required on the HP 3PAR StoreServ Storage
system. The HP 3PAR Priority Optimization has its own license key. The license is spindle-based,
available a-la-carte and as part of the Data Optimization Suite v2 available for HP 3PAR StorServ
7000 and HP 3PAR StorServ 10000 systems. Consult your HP representative or authorized HP
partner for more information on HP 3PAR Priority Optimization licensing.
Creating and managing QoS definitions requires the HP 3PAR MC 4.4 and later. To use the
command line, you must install HP 3PAR CLI 3.1.2 MU2.
Reports on HP 3PAR Priority Optimization are available through HP 3PAR System Reporter 3.1
MU1 and later, and through the HP 3PAR MC 4.4 and later. The reports on the QoS definitions
require a license for HP 3PAR System Reporter.

Virtual Volume Sets
QoS rules operate on sets of VVs called VVsets. A VVset is an autonomic group object that is a
collection of virtual volumes. VVsets help to simplify administration of volumes and reduce human
error. An operation such as exporting a VVset to a host will export all member volumes of the
VVset. Adding a volume to the VVset will export the new volume automatically to the host or host
set.
VVsets have a number of use cases beyond reducing administration for their volume members.
Most HP 3PAR Remote Copy operations are performed on sets of virtual volumes called remote
copy volume groups. VVsets also enable simultaneous point-in-time snapshots of all volumes
contained in the set with a single command. Up to 8192 volumes can be part of a VVset.
