IBM General Parallel File System (GPFS) allows users shared access to files that may span multiple disk drives on multiple nodes. It offers many of the standard UNIX® file system interfaces allowing most applications to execute without modification or recompiling.
Release 2 of GPFS for AIX® delivers several usability enhancements:
- Extended access control list entries for a file or directory.
- Support of GPFS file access by a mix of Linux or AIX clients through Tivoli® SANergy.
- Support for the creation of a single-node nodeset, allowing stand-alone AIX servers to take advantage of the hierarchical storage manager (HSM) support and large block file performance offered by GPFS.
- Ability to create a logical copy, or snapshot, of a GPFS file system.
- A new parallel backup application using Tivoli Storage Manager (TSM).
- Support for shared GPFS access by IBM pSeries® nodes running GPFS for AIX and IBM xSeries® nodes running GPFS for Linux.
- New buffer pool management code designed to enhance overall performance.
- Support using AIX 5L EtherChannel.

GPFS allows parallel applications simultaneous access to the same files, or different files, from any node in the GPFS nodeset while managing a high level of control over all file system operations. V2.2 is available for GPFS for AIX 5L. This new release runs with AIX V5.2 only.
The following capabilities are provided:
- The traditional file access modes of read, write, and execute have been extended to include a fourth access mode control. This can be used to specify who can manage the ACL for a file, other than the file owner and root user.
- If you do not have a high-speed switch in your cluster, GPFS V2.2 supports a Reliable Scalable Cluster Technologies (RSCT) peer domain (rpd) cluster running the IBM Virtual Shared Disk available with AIX V5.2 over LANs or aggregated LANs such as EtherChannel of 1 Gb/s or more.
- Support is provided for file access through Tivoli SANergy. This can allow heterogeneous access to GPFS file system data at high data rates using an extender technology which obtains metadata from GPFS but can directly access the disks that make up the file system. In GPFS, any node in the nodeset can serve as a MetaData Controller for a GPFS file system.
- GPFS provides the ability to create a logical copy, or "snapshot," of an entire GPFS file system at a single point in time. This snapshot capability is designed to allow a backup or mirror application to run concurrently with user updates and still obtain a consistent copy of the file system as of the time it was created.
- A parallel backup application using TSM Backup Client Interface is available for use with GPFS file systems. A new GPFS command enables root users to back up the files of a GPFS file system from TSM clients to storage via a TSM server. Once a file system has been backed up, the user can restore files using the interfaces provided by TSM.
- GPFS now supports an interoperable environment with GPFS for Linux on xSeries. You can mix AIX and Linux nodes running the respective GPFS offerings within the same cluster and provide access to shared file systems.
- Support for a larger GPFS pagepool allows for caching of larger data sets. Additional enhancements improve caching for very large data sets by utilizing re-access histories. Cache utilization is improved by lessening fragmentation.
Accessibility for people with disabilities
Operation by keyboard alone is a feature supported for people with disabilities.

GPFS is particularly appropriate in an environment where the aggregate peak need for data exceeds
the capability of a distributed file system server. Key strengths of GPFS are its superior
scalability and performance, its ability to support extremely large files, and its failure recovery.

IBM Software Maintenance is a one-year or three-year contract offering that enables customers to maintain software product version and release currency, with voice support during normal business hours included at no additional charge for the first year, for selected AIX and UNIX®-based software products at a predetermined cost. One year of Software Maintenance is included in the price of the original license. For products participating in IBM Software Maintenance, customers can receive all software product version and release upgrades and voice support, announced during the contract period. If customers allow either the one-year or three-year software maintenance offering to expire without renewal, there will be a "Maintenance-after-license" option to enable reinstatement in the Software Maintenance offering, on a product by product basis.
The following is general information regarding the Software Maintenance agreement:
- Each eligible licensed software program will include one year of Software Maintenance (Software Subscription and Technical Support) in the price of the license.
- A one- and three-year prepay option (represented by two separate type/models) associated with each eligible licensed program are available.
- The Software Maintenance type/models will have the same pricing structure as the license type/models they are associated with.
Each one- and three-year Software Maintenance program number will have three sets of feature numbers
for each priced entity:
- A no-charge registration feature for the one-year contracts and a two-year priced feature (since the first year is included in the price of that license) for the three-year contracts.
- A renewal feature of one or three years.
- A Software Maintenance "after license" charge for customers who want to renew but have lapsed coverage.
- The Software Maintenance order generated for this product will be a new order and have a new starting/ending period, separate from the one for the license already in effect.
Definition of software upgrade: An upgrade is either a new version (3.x.x to 4.x.x) or a new release (x.3.x to x.4.x) of an IBM program announced as eligible for which a customer enrolled under the IBM Software Maintenance. Software Maintenance entitles customers to future upgrades from only the latest announced version or release of an available eligible product.
Upgrades do not include programs sold separately from the enrolled program, but enhance the performance of that program, or are considered add-ons or utilities. Programs that perform the same functions as the enrolled program but are installed on a non-AIX platform are not considered upgrades.
Note: Software preventative-maintenance releases x.x.1 to x.x.2 (modification level changes, updates, or refreshes) are released under the one-year or three-year maintenance program numbers but only when a supply feature has been announced. Supply features are only announced under the one-year and three-year options when there is an announced version/release change against the original program product. Service fixes (no-charge preventative maintenance) should be obtained by Software Maintenance customers in the same manner as non-Software Maintenance customers.
Example: Product A is offered under IBM Software Maintenance and three months later program fixes are incorporated into the program package. This is considered an update that would not be obtained under the one-year or three-year maintenance program numbers under the IBM Software Maintenance offering. Using the same example above, three months after the program fixes were incorporated into the program package, IBM announces a new version of product A. At that time, a supply feature is announced for product A under the one-year and three-year maintenance program numbers. This allows customers who are entitled by purchase or when the first year of maintenance is included with the license, of either the one-year or three-year maintenance offering for product A to order the upgrade under the one-year or three-year offering.
IBM may announce a product that can be substituted for an enrolled product. This product is neither a new version, a new release, nor a preventative maintenance release of that enrolled product. In most cases, this product has a different architecture, more function, and a higher license charge than the enrolled product. IBM may provide those customers enrolled in the IBM Software Maintenance offering access to this product at a discounted rate. The terms of this transaction will be included in the new product announcement.
Note: IBM will not offer stand-alone upgrades as a standard product offering. Stand-alone upgrades to this product/release, and its future versions and releases, will be considered only on a special-request basis by IBM.
Contract duration: The IBM Software Maintenance contracts are on a product-by-product basis and are offered for one or three years. One year of Software Maintenance is included with the purchase of a new license for the product. The three-year prepay option covers two additional years of coverage since the first year is included in the product license. The three-year prepay option can be purchased at the same time a license for an eligible product is purchased. Refunds do not apply if cancellation occurs during the one or three year contract period. Customers are not required to renew under either the one-year or three-year offering when the contract expires but will need to use the Maintenance-after-license option should they let the contract expire and want to acquire a new version or release of an eligible product. If the one-year or three-year contracts are not renewed, the one or three year contracts will be removed from IBM administrative systems. Contract transfers within an enterprise are allowed.
Payment options: Customers enroll in the plan at a reduced "Initial" price at the same time a new license for an eligible program product is purchased. Customers can also enroll in the plan after purchase of a new license for an eligible program product but must purchase the "Maintenance-after-license" option.
Software Maintenance prices: The IBM Software Maintenance program prices are based on the published price of the software program at the time of the contract preparation.
Minimum contract value: None

IBM has transformed its delivery of hardware and software support services to put you on the road to higher systems availability. Electronic Services is a Web-enabled solution that provides an exclusive, no-additional-charge enhancement to the service and support on the IBM eServer. You should benefit from greater system availability due to faster problem resolution and preemptive monitoring. Electronic Services comprises of two separate but complementary elements; Electronic Services news page and Electronic Service Agent.
The Electronic Services news page is a single Internet entry point that replaces the multiple entry points traditionally used to access IBM Internet services and support. The news page enables you to gain easier access to IBM resources for assistance in resolving technical problems.
The Electronic Service Agent is no-additional-charge software that resides on your IBM eServer system. It monitors events and transmits system inventory information to IBM on a periodic customer-defined timetable. The Electronic Service Agent tracks system inventory, hardware error logs, and performance information. If the server is under a current IBM maintenance service agreement or within the IBM warranty period, the Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to provide proactive service that maintains higher system availability and performance. In addition, information collected through the Service Agent is made available to IBM service support representatives when they are helping answer your questions or diagnosing problems.
