What does it mean if a Storage Group is listed as "Critical" in Unisphere for VMAX?
A storage administrator has completed TimeFinder SnapVX testing. The administrator is unable to terminate the TimeFinder SnapVX snapshot of the test Storage Group.
What advice should be provided to the administrator?
A storage administrator wants to verify the state of the SLO compliance application data hosted on a VMAX3. Where can the information be found in Unisphere for VMAX?
A customer wants to know if they need to set the SCSI3_persist_reserve attribute for their VMAX3 devices used in a clustered environment. What information should be provided?
Two RDF groups from two VMAX3 arrays have been added to a RDF Consistency Group. SRDF/A Multi-Session Consistency (MSC) has been enabled for the Consistency Group. The RDF daemon has been started on a single host that has access to both the VMAX3 arrays.
What will happen if this host becomes unavailable?
When data consistency is not a requirement, which SRDF mode is preferred when replicating large volumes of data?
You are in the process of designing a VMAX3 solution with VMAX Sizer. Which parameters can be changed in a "What if Analysis"?
You are designing an SRDF/A solution with BCSD and the results of the model are shown in the exhibit. The BCSD model was run with the following settings:
Source Array: VMAX 200K, 2-engine, 2 TB cache
Number of RA Ports: 4
Network Circuit: 450 MB/s
Required RPO: 5 minutes
Which conclusion can be made based on the modeling results?
How do Service Level Objectives (SLO) capacity compliance algorithms differ from Storage Resource Pools (SRP) capacity compliance algorithms?
After an SRDF failover operation, production work has been moved to the remote site. A large number of invalid tracks have accumulated that need to be synchronized back to the R1 volumes.
Which SRDF operation can reduce the re-synchronization time, while continuing production work on the remote site?
In addition to Storage, Hosts, Performance, and Support, which other Unisphere for VMAX sections are available for selection of an individual VMAX3 array?
A VMAX3 parent Storage Group (SG) contains two child SGs: SG1 and SG2. What is a valid Host I/O limit setting for this configuration?
A TimeFinder SnapVX snapshot of source volumes has been linked to target volumes. The target volumes are being used for application testing.
What is recommended prior to a relink operation?
A VMware administrator has been tasked with managing storage for an ESXi cluster connected to a VMAX3 array. The VMware administrator is not familiar with Unisphere for VMAX and wants to use the VMware Web Client to provision VMFS datastores.
Which EMC product provides this functionality?
A VMAX3 Storage Group has Host I/O limits set at 10,000 IOPs. The Port Group contains four ports across different directors. The Dynamic Distribution is set to "Always".
What is the maximum IOPs the Storage Group can achieve in the event a switch port being used by one of the director ports fails but the director remains online?
What is the best practice sizing guideline for front-end (FA) utilization on a two-engine VMAX3?
