Q

What is a limitation in adding and removing director emulations in PMax?

A

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

Q

What is Slot 7 used for on multi-engine PowerMax 8000 builds?

A

compression and deduplication module is located here

19
Q

What is Slot 10 used for on multi-engine PowerMax 8000 builds?

A

where fabric modules are installed

fabric module 0 and 1 connected to InfiniBand switches

20
Q

What are ports 4-11 and 24-27 used for on single-engine PowerMax 8000 builds?

A

FE or remote connectivity

port numbers don’t become available unless an IO module is put in the slot

21
Q

What are ports 12, 13, 16, and 17 used for on single-engine PowerMax 8000 builds?

A

BE connectivity

22
Q

What is Slot 9 used for on multi-engine PowerMax 8000 builds?

A

compression and deduplication module installed here

23
Q

What module on multi engine PowerMax 8000 builds is missing on single engine builds?

A

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

24
Q

Besides a fabric module what else is necessary to install when upgrading from a single to multi-engine PowerMax 8000?

A

second engine also requires a pair of InifiniBand switches to be installed

25
Q

What are ports 4-11 and 24-31 used for on PowerMax 2000 builds?

A

FE and remote connectivity

26
Q

What are ports 12, 13, 16, and 17 used for on PowerMax 2000 builds?

A

BE connectivity

27
Q

What is slot 7 used for on PowerMax 2000 builds?

A

compression and deduplication module installed here

28
Q

When are fabric modules installed on PowerMax 2000?

A

on multi-engine systems only

ports 0 and 1 on module 10 used for inter-engine connectivity

29
Q

What are ports 4-11 and 24-27 used for on VMAX 950F builds?

A

FE and remote connectivity

30
Q

What are ports 12-19 used for on VMAX 950F builds?

A

BE connectivity

31
Q

What is slot 9 used for on VMAX 950F builds?

A

32
Q

When are fabric modules installed on VMAX 950F?

A

on multi-engine systems only

ports 0 and 1 on module 10 used for inter-engine connectivity

33
Q

What are ports 4-11 and 24-31 used for on VMAX 250F builds?

A

FE and remote connectivity

34
Q

What are ports 12-15 used for on VMAX 250F builds?

A

BE connectivity

35
Q

What is slot 7 used for on VMAX 950F builds?

A

compression and deduplication module installed here

36
Q

When are fabric modules installed on VMAX 250F?

A

on multi-engine systems only

ports 0 and 1 on module 10 used for inter-engine connectivity

37
Q

What port attribute is provided for FE connectivity on VMAX/PMax?

A

permit the setting of SCSI/fibre flags at the front end level

FE ports can be shared by multiple hosts

38
Q

What if you’re using hosts w/ two different OSs and connecting them to PMax/VMAX?

A

different OSs need different bits and flags set on the FE port to recognize devices

39
Q

What is the role of ACLX flags?

A

enable storage autoprovisioning for the port

40
Q

Is it possible to override port flag settings?

A

can be overriden at the initiator group level

41
Q

How should hosts be connected on PMax/VMAX?

A

should access devices over two or more ports

42
Q

When can you associate a port in PowerMax/VMAX?

A

free ports can be associated with a desired director emulation

43
Q

What must you do before disassociating a port in PowerMax/VMAX?

A

ensure that a FE port is not in a port group or the RDF port does not have any RDF groups configured

ports must be offline before disassociating
