A storage administrator uses Unisphere for VMAX to provision new Storage Groups on a VMAX3 array. Which Workload Type is recommended for small block I/O workloads?
What is the effect of a failed Suitability Check while provisioning storage on a VMAX3?
The Storage Group containing the source volumes on a VMAX3 array is managed by the Gold SLO. A TimeFinder SnapVX snapshot of this Storage Group is linked to target volumes. The Storage Group containing the target volumes is managed by the Bronze SLO.
Which SLO will be used to manage the snapshot deltas?
From an application perspective, what should be done prior to performing an SRDF restore operation?
From an application perspective, what should be done prior to performing an SRDF failback operation?
Where will TimeFinder SnapVX snapshot deltas be stored on a VMAX3 array?
A customer is interested in migrating applications stored on EMC VNX arrays to a new VMAX3 array. You need to design the new VMAX3 array with VMAX Sizer.
Which data should be imported into VMAX Sizer to complete the sizing?
Which database does Unisphere for VMAX 8.0 use for Performance Analyzer?
What is the maximum number of linked targets that TimeFinder SnapVX supports?
You are proposing a VMAX3 solution with mixed drive types to a customer. The customer wants to understand the relationship between Service Level Objectives and drive types.
Which drive types will the Platinum SLO use under most circumstances?
Based on best practice, which drive combination is used in VMAX3 two-tier configurations?
You are in a meeting with a customer to discuss virtual provisioning on VMAX3 arrays. The customer wants information on extent allocation during thin device creation.
How many extent(s) are allocated when a thin device is created?
A customer wants to implement SRDF/S for an application. The application is performing at 10,000 IOPS and is using many volumes. The size of the I/O is 4 KB. Forty percent (40%) of the IOPS are writes. Assume an RA can handle a maximum of 4,000 4 KB IOPS.
Based on best practice, how many RAs should be recommended?
A TimeFinder SnapVX snapshot of the Storage Group containing four devices is created at 10 AM. The storage administrator adds another device to this Storage Group at 2 PM. A second snapshot of the Storage Group is created at 3 PM. The 3 PM snapshot is used to perform a restore operation at 4 PM.
What will be the status of the newly added device after the restore operation?
During a scheduled outage of the primary site (R1), a company is operating their production on their disaster recovery site (R2). After the outage, they need to move production back to the R1 site.
