Q

What does eManagement do on PowerMax/VMAX?

A

enables customers to run array management software components inside of array

17
Q

What does Dell EMC Solutions Enabler allow on PowerMax?

A

provide array management and control of the arrays

18
Q

What are the data reduction technologies available on PowerMax and VMAX?

A

inline compression

19
Q

What is true about compression in PowerMax/VMAX?

A

enabled by default

new IO to a SG is compressed when written to disk

if there is existing data on the SG it starts to compress in the background

20
Q

What happens if you turn compression off in PowerMax/VMAX?

A

new IO is no longer compressed and existing data remains compressed until it is written again (at which time it will decompress)

21
Q

What data is compression available on?

A

open systems (FBA) data only

includes eNAS data

22
Q

What is true about deduplication in PowerMax/VMAX?

A

can’t operate independent of compression (must have compression on to enable dedupe)

operates across entire system (not possible to use compression only on some SGs and compression + dedupe on others)

available on open systems (FBA) only

23
Q

What are the data reduction technologies available only on PowerMax?

A

inline compression + Deduplication

24
Q

What is PowerProtect Storage Direct?

A

integration between PowerMax or VMAX arrays and Data Domain to back up production data

25
Q

How does PowerProtect Storage Direct work?

A

TimeFinder SnapVX is used to create a snapshot of a LUN

Storage Direct copies the snapshot to DD system

change tracking is enabled so only changes made are copied

26
Q

How many hosts can PowerPath software on PowerMax support?

A

75

27
Q

What does PowerPath do?

A

dynamically routes IO to the most efficient paths using patented algorithms to balance workloads

28
Q

What is the advantage of using PowerPath?

A

users gain the automated data path management and load balancing for all heterogenous servers, network, and storage

enables more predictable application availability and up to three times the IOPS

29
Q

What is eNAS on PowerMax?

A

embedded network attached storage

extends file level storage to PowerMax/VMAX

30
Q

How does eNAS work?

A

storage hypervisor on the array manages and protects embedded services by extending high availability to these services that traditionally run outside of the array

31
Q

What are the software components that provide the NAS services on PowerMax and VMAX?

A

Data Movers
Control Stations

32
Q

What are the protocols that work w/ PowerMax/VMAX?

A

FC, iSCSI, CIFS, SMB, NFS
