PowerMax and VMAX All Flash Solutions Design (PowerMax and VMAX All Flash Port Management) Flashcards
(43 cards)
How many slices are their per director board in VMAX/PMax?
8
each slide can contain a specific emulation for use
single emulation instance of a specific type per director board
How can one add or remove director emulations in PMax?
using either Unisphere or Solutions Enabler
What is a limitation in adding and removing director emulations in PMax?
only FE and remote director emulation can be added or removed
emulations can only be modified in slices D-H
an available slice must be present to add an emulation
What can slices A-C director emulations be used for?
reserved for internal and BE simulations
What happens if an emulation type already exists on a director board?
another instance of that emulation cannot be added to the director board
Where do you add emulations in Unisphere?
System section
choose Hardware and than click the Manage Emulation button
What version of Solutions Enabler allows you to add or delete emulations?
SE 8.2 or higher
What are the emulation types in PowerMax?
IM
EDS
DS
FA
RF
RE
EF
What is the IM emulation?
infrastructure management
places common infastructure tasks on a separate instance to optimize CPU resources
provides all environmental monitoring and servicing
What is the EDS emulation?
enginuity data services
merges the gap between FE and BE emulations
runs algorithms for read/write and provides multithreading infrastructure for core services like replication and data reduction
What is the DS emulation?
backend emulation
What is the FA emulation?
fibre adapter
runs the FC emulation
What is the RF emulation?
SRDF/FC
What is the RE emulation?
SRDF/Ethernet
What is the EF emulation?
runs the FICON emulation for mainframe connectivity
What are ports 4-11 and 24-31 used for on multi-engine PowerMax 8000 builds?
FE or remote connectivity
port numbers don’t become available unless an IO module is put in the slot
What are ports 12, 13, 16, and 17 used for on multi-engine PowerMax 8000 builds?
BE connectivity
What is Slot 7 used for on multi-engine PowerMax 8000 builds?
compression and deduplication module is located here
What is Slot 10 used for on multi-engine PowerMax 8000 builds?
where fabric modules are installed
fabric module 0 and 1 connected to InfiniBand switches
What are ports 4-11 and 24-27 used for on single-engine PowerMax 8000 builds?
FE or remote connectivity
port numbers don’t become available unless an IO module is put in the slot
What are ports 12, 13, 16, and 17 used for on single-engine PowerMax 8000 builds?
BE connectivity
What is Slot 9 used for on multi-engine PowerMax 8000 builds?
compression and deduplication module installed here
What module on multi engine PowerMax 8000 builds is missing on single engine builds?
no fabric module on single engine systems
engine upgrade requires fabric module to be installed in slot 10 on every director board to connect to InifiniBand switches
Besides a fabric module what else is necessary to install when upgrading from a single to multi-engine PowerMax 8000?
second engine also requires a pair of InifiniBand switches to be installed
