Hi, This fileset comes with the GPFS package. If you have gpfs installed in the system then you would get it from the gpfs base bundle.

It is a product of and is short for General Parallel File System. It is a high-performance shared-disk file system that can provide fast data access from all nodes in a homogenous or heterogenous cluster of IBM UNIX servers running either the AIX or the Linux operating system. All nodes in a GPFS cluster have the same GPFS journaled filesystem mounted, allowing multiple nodes to be active at the same time on the same data. A specific use for GPFS is RAC, 's Real Application Cluster. In a RAC cluster multiple instances are active (sharing the workload) and provide a near 'Allways-On' database operation. The Oracle RAC software relies on 's HACMP software to achieve high availability for hardware and the operating system AIX. For storage it utilizes the concurrent filesystem called GPFS. Data availability GPFS is fault tolerant and can be configured for continued access to data even if cluster nodes or storage systems fail. This is accomplished though robust clustering features and support for data replication. GPFS continuously monitors the health of the file system components. When failures are detected appropriate recovery action is taken automatically. Extensive logging and recovery capabilities are provided which maintain metadata consistency when application nodes holding locks or performing services fail. Data replication is available for journal logs, metadata and data. Replication allows for continuous operation even if a path to a disk or a disk itself fails. GPFS Version 3.2 further enhances clustering robustness with connection retries. If the LAN connection to a node fails GPFS will automatically try and reestablish the connection before making the node unavailable. This provides for better uptime in environments experiencing network issues. Using these features along with a high availability infrastructure ensures a reliable enterprise storage solution. GPFS interaction with AIX GPFS is a means to provide a journaled filesystem that can be mounted on multiple nodes simultaneously. GPFS stripes the data across all disks that belong to that file system. GPFS has a somewhat different approach of dealing with AIX volume groups and disks as we're used to; also mirroring is done in a different way. A standard AIX setup has a device relationship that follows the following rules: A volumegroup is created that holds one or more physical disks. A disk contains one or more logical volumes, or a logical volume may span multiple disks. There is a one-to-one relation between a logical volume and the filesystem it contains. Saathi re serial star one. With LVM-mirroring each logical partition of a logical volume is placed on two separate disks. This typical setup is shown in the figure below: The original AIX filesystem structure. In a SAN environment, this picture looks like this: The AIX filesystem structure in a SAN environment. Each volume group of GPFS contains only 1 (one) physical disk. Each disk contains only 1 (one) logical volume. Each filesystem contains multiple logical volumes (one for each disk). LVM mirroring is not supported (there is only one disk in a volume group). This translates in the following picture: The GPFS filesystem structure in a SAN environment. In GPFS 2.3 the GPFS volumes are called Network Storage Devices (NSD), that contain each only one physical disk. No volume groups and/or logical volumes are created in this GPFS version. In migrated clusters (from GPFS 2.2 to GPFS 2.3) you will still see volume groups and logical volumes, but only for the 'old' disks. New disks and filesystems will be created without them. We change the picture in a more 'stack'-like representation. Here you see one GPFS filesystem that is made up out of four separate disks. AIX multipath-software has created the hdisk and vpath devices. On the AIX level GPFS creates a separate volume group for each disk, so 4 volume groups in total. GPFS fills each disk with a logical volume, so 4 logical volumes in total. These logical volumes are represented as disk in the GPFS configuration. These GPFS-disks are used in the filesystem. A file stored in the filesystem is striped across the four disks (in 8kb blocks). UTorrent plus Serial Key 3.4.2 let you play media stream as you download media files. It supports all these: protocol encryption, DHT, Peer Exchange, web interference and PSS feeds. Hd plus karte keygen torrent. It has highly detailed stats, support for RSS feeds, automatic shutdown, download scheduler and more. UTorrent plus Key has anything you would expect from a complete and reliable downloader. The command used to create the GPFS disks is mmcrlv. The stacked GPFS filesystem structure. Usually, only small LUNs of only 17,5 GB are used instead of big luns (of 400 GB), because of performance. Mirroring versus replication Traditional AIX mirrorring on the logical volume level can not be done in a typical GPFS device setup. The volume group holds only one disk that is completely filled with one logical volume, so there is no destination possible for the second copy of the lv's logical partitions. GPFS provides replication as the alternative. GPFS provides a structure called replication that provides a means of surviving a diskfailure. On the file level you can specify how many copies of that file must be present in the filesystem (one or two).
