|2121||9.1GB Disk, Eight Pack||69.84||61.5||52.58|
|2122||18.2GB Disk, Eight Pack||140.00||122.74||105.20|
|2132||18.2GB Disk, Eight Pack-Step Ahead||140.00||122.74||105.20|
|2123||36.4GB Disk, Eight Pack||280.32||245.53||210.45|
|2133||36.4GB Disk, Eight Pack-Step Ahead||140.00||122.74||105.20|
|2124||72.8GB Disk, Eight Pack||561.04||491.08||420.95|
|2134||72.8GB Disk, Eight Pack-Step Ahead||561.04||491.08||420.95|
Planned availability for the 72.8GB disk drives is December 14, 2001 with the exception of new machine orders with intermix of 72GB Disk Eight-Pack features (#2124 and #2134) with other Disk Eight-Pack features (#2121, #2122 and #2123) which has a planned availability of January 25, 2002.
New configuration options
In Announcement Letter 101-341, IBM announced the following new configuration options:
- Disk drive capacity intermix support for improved flexibility and additional configuration options
- Support for CUIR and high capacity 32,760 cylinder 3390 volumes
- Support for Intel servers running Linux
- Subsystem Device Driver (SDD) support for Windows 2000 cluster configurations and AIX 5L V5.1
- Command Line Interface (CLI) support extended to the Novell NetWare environment
- PPRC performance improvements during the establish phase when using the INRANGE 9801 Storage Network System, enabling data movement and migration over greater distances
- Feature conversions to exchange host adapters
- Replacement power cords available as optional features
- Call home and remote support capabilities enhanced with availability of IBM TotalStorage Enterprise Storage Server Master Console which replaces the Remote Support Facility (ESSNet)
Disk drive intermix and additional configuration options
The ESS now supports intermixing of the 9GB, 18GB, 36GB and new 73GB disk devices on an SSA loop. It is available on all models and any quantity of available Disk Eight-Pack features (#212x) can be intermixed as long as they are purchased in increments of two and supported on a given ESS model. This support is also available in Step Ahead configurations.
Intermix support does require the new Flexible Capacity Option features (#9500 and #9600), which replace the Standard Configuration features that were previously used when specifying ESS capacity and disk device type.
The Step Ahead program and capacity configuration options have been enhanced with the Step Ahead Flexible Capacity option (#9500). It replaces the Step Ahead Standard Configuration features, and offers the following:
- Ability to purchase Step Ahead Disk Eight-Packs (#213x) of any type, independent of the type of Disk Eight-Packs (#212x) installed in the ESS, versus the previous restriction of having to purchase same type (or capacity).
- Ability to purchase new Step Ahead Disk Eight-Packs of a different type than the previous Step Ahead Disk Eight-Packs.
- Ability to purchase any type and quantity of available Disk Eight-Pack (#212x) features as long as they are purchased in increments of two and supported on a given ESS model, versus previous restriction of having to purchase same type.
- Ability to purchase an empty Expansion Enclosure (#2100) to be populated with disk eight-packs at a later date, versus the previous restriction of purchasing only when the number of disk eight-pack features exceeded sixteen.
- Ability to purchase capacity within the Expansion Enclosure in increments of two disk eight-packs, versus previous restriction of four disk eight-packs
- Maximum number of Step Ahead Disk-Eight Pack features per machine limited to two.
- Step Ahead Disk Eight-Packs now price to include the Step Ahead fee.
- Additional Disk Eight-Packs (#212x) can be purchased without a new Step Ahead fee charge.
- If Step Ahead storage is not purchased within one year, but additional Disk Eight-Packs (#212x) have been purchased within last year, then customers can remain in the program with the Step Ahead Annual Renewal features (#216x)
CUIR support is available in zSeries 900 and S/390 environments. This eliminates customers from having to be concerned with manually determining path status and invoking the needed status changes.
32,760 cylinder 3390 volumes
IBM stated that support of 32,760 cylinder 3390 volumes provides the ability to consolidate multiple disk volumes into a single address, and that this can help relieve address constraints, improve disk resource utilization, reduce the frequency of multi-volume data sets, and improve storage administrator productivity.
PPRC performance improvements with INRANGE 980
IBM stated that enhancements to the INRANGE 9801 SNS exploit the PPRC Establish Copy design, allowing data to now stream across the network without unnecessary intermediate messages (protocols) for data transmission, and that this would improve performance when data is transferred over long distances.
Planned availability dates
The planned availability dates for each of the above enhancements is as follows.
November 13, 2001
- SDD support for Windows 2000 cluster configurations
- CLI support for Novell NetWare
November 30, 2001
- Disk eight-pack intermix for MES orders only
- CUIR support for z/OS and OS/390
- 32,760 cylinder 3390 volume for z/OS and OS/390
- Attachment and CLI support for Intel servers running Linux
- SDD support for AIC 5L
- Flexible Capacity Option feature number structure
- Increments of two Disk Eight-Packs (#212x) within the Expansion Enclosure

Evaluator Group comments:
The major enhancement provided with these announcements is improved scalability. The support of the 72.8GB drives increases the maximum subsystem capacity of the ESS to over 22TB. This increase in capacity, combined with the ability to intermix the various drive capacities, makes the ESS much more competitive with the EMC Symmetrix and Hitachi 9900.=====================================================
