Diamond
What must you do to rename a SL?
must be a user w/ storage admin rights in Unisphere
have HYPERMAX OS 5977 or higher
SL name must be unique and less than 32 characters
What makes up the Efficiency value on the Unisphere Dashboard?

What is Subscription in terms of an SG Demand Report?
the total provisioned capacity (allocated + free to be allocated)
What is Allocated in terms of an SG Demand Report?
the storage capacity an SG has been allotted in its subscription
What is Used in terms of an SG Demand Report?

What is Compression Ratio in terms of an SG Demand Report?
ratio between the original size of the data and its size after being compressed
What is Workload Planner (WLP)?
software layer that abstracts the array as a provider of services
converts array status (disks, ports, directors) to array capabilities
How does WLP in Unisphere work?
uses SL sizing methods
What are the main WLP features called?
Headroom Indicator
Suitability Check
What is a Headroom Indicator?
gauges the remaining capacity per SL
enables planning how many workloads can be provisioned
What is a Suitability Check?
determines if the capacity and SL request can be met by the arrays current workload
What must be on in order to use WLP?
requires array is registered for performance data collection
What is WLP primarily used for?
to display performance metrics for applications
model the impact of migrating workload from one storage system to another
What OS must a system have to run WLP?
Enginuity OS 5876
HYPERMAX OS 5977
What are the criteria for an SG to be eligible for WLP?
must be on locally attached storage system registered for performance planning
must belong to only one masking view
must contain only FBA volumes
must be managed by a Unisphere server installed on an on prem host
What are the criteria for an SG to be eligible for WLP specifically for systems running HYPERMAX OS 5977?
SGs must be associated w/ an SL
What are the criteria for an SG to be eligible for WLP specifically for systems running Enginuity 5876?
SGs must be associated w/ a FAST policy
What is the Data Exclusion Window feature?
enables excluding specific performance statistics that affect reporting

Recurring System Data Exclusion - one week of data
What is required to run Suitability Check?
HYPERMAX OS 5977 or higher
What is Dell Virtual Storage Integrator (VSI)?
plug-in for VMWare vCenter
enables admins to perform Dell storage management tasks from vCenter
admin uses vCenter client to manage/provision storage
What are the two parts of VSI?
GUI

What is Dell EMC SIS?
programming interface that provides communications to the storage and data protection systems
What is required for PowerMax to use VSI?
have Unisphere/PowerMax OS 9.X
