Storage Scale (formerly known as GPFS)

Showing 535 of 5528

Multiple block sizes at the pool level

Pools could be configured with different block sizes (not metablocks) based on workload requirement.
over 10 years ago in Storage Scale (formerly known as GPFS) 5 Not under consideration

SNMP 64 bit counters + CIM support

Proper 64 bit counters. Obtaining correct SNMP values (E.G. for pool sizes) is not as simple as it should be.
over 10 years ago in Storage Scale (formerly known as GPFS) 4 Not under consideration

AFM queue control

Complete control over the order of each prefetch (analogy: priority WAN transfer queue for GPFS)
over 10 years ago in Storage Scale (formerly known as GPFS) 3 Not under consideration

Pool placement based on path

Ability to place data into a pool based on the directory location of the data.

mmfsck -P poolname

Checking a file system with multiple pools means results in a check of the entire metadata for the file system when each pool is checked.  Not optimal.  Check individual pools instead.

Globally accessible and coherent cache

A cached block is cached on all nodes and hence accessible from all nodes
over 10 years ago in Storage Scale (formerly known as GPFS) 4 Not under consideration

Ability to flush / clear the cache (not to disk)

The cache on a node should be able to be cleared without unmounting and remounting the file system
over 10 years ago in Storage Scale (formerly known as GPFS) 5 Not under consideration

[BDA] Ability to see what is in the cache

Use:  mmlscache gives containing directory, file, size/blocks, % used of cache, cache hits, last access time etc.  -Y option
over 10 years ago in Storage Scale (formerly known as GPFS) 7 Not under consideration

[BDA] Cache control via runtime policy engine

If caching could be controlled by the policy engine, the user could intelligently control that valuable resource with respect to their known workloads / data types.

Management and control of GPFS disk area and Tape Quota

<Requirement>GPFS fileset quota can control not only for on the disk, but also on the tape with LTFS EE.
