FEATURE DESCRIPTION
FLASHCOPYPERFORMANCEIMPROVEMENTS
FlashCopy and related TrueCopy and HUR performanceimprovements.
TPC-R AND BASICHYPERSWAP
The ability to configure 2 and 3 data center environmentsusing Tivoli Storage Productivity Center for Replication(TPC-R) and automate HyperSwap between sites andcontrol units within the same center.
TPC-R SUPPORT
FOR METROMIRRORFAILOVER

VSP G1000 Mainframe Features
FEATURE DESCRIPTION
HTSM SupportMicrocode release adds support for HTSM
HierarchicalMemory (VMA)
Enables larger number of bitmaps as well as supportlarger volumes and LUNs by using a new hierarchicalapproach. Bitmap information will spread across localprocessor memory, (traditional share memory), anddisk drives
1TB (EAV)
EXTENDEDADDRESSVOLUME
1TB EAV is a volume with more than 65,520 cylinders.
EAV increases the amount of addressable DASD storage per volume beyond 65,520 cylinders by changing howtracks on ECKD volumes are addressed

VSP G1000 Mainframe Features
FEATURE DESCRIPTION
Z/HPFBSAM QSAM
System z High-Performance FICON (zHPF) supports additionalworkloads using QSAM and BSAM access methods.
Z/HPFFORMATWRITE
zHPF format writes this function speeds DB2 loads,reorganizations, index rebuilds, and database restores. Additionally, DB2 load throughput with DB2 9 and 10 increasesas much as 52 percent using 4K pages.
Z/HPF ANDDB2 I/O
All DB2 I/O can convert to zHPF. When z/OS preformats DB2data sets, zHPF enables a 15-to-2 reduction in the number ofI/Os an especially signification reduction when used withsynchronous replication technologies such as peer-to-peerremote copy

VSP G1000 Mainframe Features
FEATURE DESCRIPTION
Z/HPFDB2 LISTPREFETCH
With FICON Express8S, zHPF DB2 list prefetch reduceschannel connect time by up to 2.5 times. DB2 10 uses listprefetch for disorganized index scans.
Z/HPF BI-DIRECTIONALCHANNELPROGRAM
DB2 exploitation of zHPF will improve performance byallowing Media Manager to exploit bidirection zHPF I/Osupport
Z/HPFLISTPREFETCHOPTIMIZER
zHPF List Prefetch Optimizer is used by DB2 technology to exploitthe ability of the System z I/O architecture to read discontinuousdisk segments in single I/O operations

FEATURE DESCRIPTION
GDPS PPRCSUM
When compared to reporting suspensions on a per-devicesbasis, the Summary Event Notification for PPRC Suspends(PPRCSUM) dramatically reduces the message traffic andextraneous processing associated with PPRC suspensionevents and freeze processing
GDPSHYPERSWAPStorageControl HealthMessage
This new attention message will be generated from thehardware, 1 per corresponding logical storage system, toalert the operating system of a condition that in the pastwould have surfaced as a general equipment check. This
message will give more details and is intended to reduce thenumber of false HyperSwap events that have occurred withthe less descriptive equipment check
