96
What are the max drives on PowerMax 8000?
288
What are the max drives on VMAX 250F?
100
What are the max drives on VMAX 950F?
1920
What is the benefit of the Dynamic Virtual Matrix?
enables hundreds of CPU cores to be pooled and allocated on-demand to meet the performance requirements for dynamic mixed workloads
How does the Dynamic Virtual Matrix work?
resources are dynamically apportioned to host applications, data services, and storage pools to meet application service levels
How does provisioning work on PowerMax/VMAX?
all virtually provisioned
How are PowerMax/VMAX configured?
come preconfigured from factory
creates all required data pools and RAID levels for the configuration in the array
What are Management Module Control Stations (MMCS) in PowerMax/VMAX?
integrated service processor that provides environmental monitoring of arrays
What does eManagement do on PowerMax/VMAX?
enables customers to run array management software components inside of array
What does Dell EMC Solutions Enabler allow on PowerMax?
provide array management and control of the arrays
What are the data reduction technologies available on PowerMax and VMAX?
inline compression
What is true about compression in PowerMax/VMAX?
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
What happens if you turn compression off in PowerMax/VMAX?
new IO is no longer compressed and existing data remains compressed until it is written again (at which time it will decompress)
What data is compression available on?
open systems (FBA) data only
includes eNAS data
What is true about deduplication in PowerMax/VMAX?
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
What are the data reduction technologies available only on PowerMax?
inline compression + Deduplication
What is PowerProtect Storage Direct?
integration between PowerMax or VMAX arrays and Data Domain to back up production data
How does PowerProtect Storage Direct work?
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
How many hosts can PowerPath software on PowerMax support?
75
What does PowerPath do?
dynamically routes IO to the most efficient paths using patented algorithms to balance workloads
What is the advantage of using PowerPath?
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
What is eNAS on PowerMax?
embedded network attached storage
extends file level storage to PowerMax/VMAX
How does eNAS work?
storage hypervisor on the array manages and protects embedded services by extending high availability to these services that traditionally run outside of the array
What are the software components that provide the NAS services on PowerMax and VMAX?
Data Movers
Control Stations
What are the protocols that work w/ PowerMax/VMAX?
FC, iSCSI, CIFS, SMB, NFS
