[gpfsug-discuss] GPFS on PowerVM Shared Storage Pools

2017-03-23 Thread Stephen Ulmer
I have a client who is very enamored with PowerVM Shared Storage Pools (because they work great for them). Has anyone here implemented GPFS on such? I think that technically there’s no reason that it wouldn’t work, but I’ve never actually "owned" an installation with GPFS on SSPs. Any

Valdis,   GPFS 4.2.2.3 will be supported with LTFS EE 1.2.3.0 when it is released on 3/31.  This new release of LTFS EE adds support for AFM + LFTFS EE.  If you need GPFS 4.2.2.3, then 1.2.3.0 is where you need to go.  Kevin D. Johnson, MBA, MAFMSpectrum Computing, Senior Managing ConsultantIBM
