December 19, 2000
General Parallel File System V1R4 Now Supported on Clusters of RS/6000 Workstations and Servers Running HACMP
At a Glance
General Parallel File System (GPFS) V1R4 for AIX extends the benefits of GPFS to the cluster environment, and provides new support for directly-attached SSA disks.
GPFS is a fast, highly available, and highly scalable, shared file system for clusters of IBM's UNIX® systems; both IBM pSeries and IBM RS/6000 workstations and/or servers running HACMP/ES.
For ordering, contact:
Your IBM representative, an IBM Business Partner, or IBM Americas Call Centers at 800-IBM-CALL (Reference: RE001).
General Parallel File System for AIX® is now available on your clusters of RS/6000® servers and workstations. This will enable you to move data quickly into and out of the node clusters, with high availability among nodes.
GPFS V1R4 provides the capability to share data across Serial Storage Architecture (SSA) shared disks or disk arrays directly attached to multiple RS/6000 workstations or servers running AIX V4R3.3 and HACMP/ES V4R4. In this environment, a GPFS nodeset consists of up to eight nodes.
In addition, GPFS now provides the capability to operate in an SP environment with directly attached disks. Here, SSA shared disks or disk arrays are directly attached to each node in the nodeset, which consists of up to eight nodes.
Note: There is no SP switch requirement for GPFS in this environment, however, HACMP/ES is a requirement in this case.
Additional enhancements to both the SP and cluster environments include dynamic addition of nodes to a GPFS nodeset when using TCP/IP as the GPFS communications protocol, and support for a single-node quorum in a two-node nodeset.
GPFS V1R4 does not support running with the SP Switch2 at availability. Refer to the Statement of Direction .

For RS/6000 SP Systems without a Switch
General Parallel File System (GPFS) provides file system services to parallel and serial applications running on the AIX Operating Environment. GPFS allows parallel applications simultaneous access to the same or different files from any node in the GPFS nodeset while managing a high level of control over all file system operations. A nodeset is a group of nodes that all run the same level of GPFS and operate on the same file system. Serial applications are dynamically assigned to processors based on availability and achieve high performance access to their data from wherever they run.
GPFS provides the capability to operate in:
In a switch environment, a nodeset consists of a set of SP nodes that provide access to GPFS file systems. Here, GPFS takes advantage of the SP Switch speed and uses it to accelerate parallel file operations that would overload serial file system management.
In a non-switch environment, a GPFS nodeset consists of up to eight RS/6000 workstations, servers, or SP nodes with uniform disk access, thus enabling concurrent data sharing. In this environment, SSA shared disks or disk arrays are directly attached to each node in the nodeset.
In both SP environments, there can be multiple GPFS nodesets per SP partition, however, a GPFS file system may only be accessed from a single nodeset.
A non-SP, GPFS cluster is a group of RS/6000 workstations or servers. This cluster is a subset of a predefined HACMP/ES cluster. In this environment, a GPFS nodeset consists of up to eight RS/6000 servers and/or workstations with uniform disk access enabling concurrent data sharing. After a GPFS nodeset has been configured, GPFS obtains the necessary configuration data from the HACMP/ES global Object Data Manager (ODM).
The following commands have been added to support this new environment:
Additional functions are available in all GPFS environments:
Note: The maximum number of supported nodes in a GPFS cluster is eight due to the limitations of the SSA adapter.

This program is not impacted by euro currency.
For IBM pSeries scientific and technical computing users, GPFS provides a single, global file system for multiple nodes, workstations, and servers, and is ideal for high performance parallel file transfer and parallel I/O to single or multiple files. For pSeries Business Intelligence usage, GPFS provides parallel enablement for applications such as SAS, improves performance of database loading utilities, and supports parallel operation of online analysis processing using tools not enabled for parallel use. For pSeries server consolidation use, GPFS provides a fast, global file system for applications sharing data within the cluster.
Users of SP systems who want to use GPFS with the SP Switch2 should use GPFS Release 3 until GPFS Release 4 is updated with SP Switch2 support. Refer to Statement of Direction.
Statement of Direction
General Parallel File System V1R4 Support of the SP Switch2
As of this announcement, GPFS V1R4 does not support running with the SP Switch2.
In order to keep the pSeries software products at the latest switch technology, IBM intends to provide support for the SP Switch2 on SP Systems running GPFS V1R4. It is expected that this support will be provided in the first half of 2001.
All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objective only.

Specified Operating Environment
Additional hardware is required to operate in a switch environment:
Additional hardware is required to operate in a direct-attached disk environment:
There can be only one GPFS cluster per HACMP/ES cluster. V1R4 does
not support the SP Switch2. V1R4 supports a maximum of eight nodes when
operating (1) in the cluster environment and (2) with directly attached
disks in the SP environment. V1R4 does not support LAPI communication as
the GPFS communication protocol in the cluster environment.
Planning for your disk subsystem in a GPFS cluster environment includes determining:
Coexistence Guidelines in Cluster Environment
Installability: The default communications protocol for communication between nodes in a GPFS nodeset is TCP/IP. This is the only supported communication protocol in a cluster (non-SP switch) environment.
Security, Auditability, and Control
General Parallel File System uses the security and auditability features of the AIX Version 4 Operating System and the RS/6000 SP.
The customer is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communication facilities.
GPFS V1R4 has one charge unit based on installations. One-time charge (OTC) feature numbers are available in variable order quantities based on the number of nodes in your RS/6000 SP system, or the number of workstations or servers in your cluster, that will be running GPFS.
General Parallel File System V1R4 is available for those customers currently licensed for GPFS V1R1, GPFS V1R2, or GPFS V1R3. Upgrades may be acquired up to the current level of use authorized for the qualifying programs.
