Our Standard Symmetrix DMX Setup
- 000 Volume Logics database (8mb)
Contains information as to what host has access to which meta devices. Should be read only to everyone except systems with Solutions enabler installed.
- 001-00F Gate Keepers (3mb)
All EMC software (TimeFinder, SRDF, SDR, etc.) run IN the Symmetrix, so servers (with SYMCLI or ECC) only issue commands to the Symmetrix and Symmetrix perform the job internally. The problem is that Symmetrix boxes can not assign memory for software, only devices, so (cleverly) EMC creates tiny devices of 6 cilinders (aprox. 2,88 MB) in order to give the requiered memory IN the Symmetrix, so symm box can receive the commands from symcli/ECC through gatekeeper devices (to the symmetrix memory) and perform it.
- 010-019 Quarum Devices (range from 70-668mb)
Quarum devices for windows clustering.
- 01A-01B Symmetrix File systems (2878mb)
For use by EMC CE only
- 01C-01F Sym Optimizer Devices (8632mb)
Used by Symm Optimizer to move hot spots in the Sym
- 020-### Meta devices pathed out to hosts in increments of 8.43G
Actual meta devices as seen by hosts.
