A TimeFinder SnapVX snapshot of source volumes has been linked to target volumes. Target volumes are accessed by a host and changes are made. These changes need to be copied back to the source volumes.
Which mode should the target have been linked to enable a restore from them?
SRDF/A has been enabled between two VMAX3 arrays. An extended loss of all RDF links occurs. What will the RDF pair state be after link connectivity is restored?
Based on best practice, which drive combination is used in VMAX3 two-tier configurations?
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 Bronze SLO use under most circumstances?
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?
How do Service Level Objectives (SLO) capacity compliance algorithms differ from Storage Resource Pools (SRP) capacity compliance algorithms?
What is a consideration when designing an SRDF/A solution between a VMAX3 array and an older VMAX 40K array?
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?
SRDF/A has been enabled between two VMAX3 arrays. Due to a loss of all RDF links, the SRDF/A session has been placed in a Transmit Idle state.
What happens to cycle switching and the delta sets?
You need to design a VMAX3 eNAS solution with VMAX Sizer. Which parameters need to be specified in the eNAS Properties tab while creating the eNAS instance?
You are designing an SRDF/S solution. Network bandwidth can be purchased in increments of single OC3 (155 Mb/s) links. Data compression is not in use. The workload profile is as follows:
Total I/Os per second = 30,000
Read block size = 4 KB
Write block size = 4 KB
Writes = 30%
How many OC3 links will provide sufficient bandwidth?
Which options can be selected in System Registrations for performance data collection in Unisphere for VMAX version 8.0?
Refer to the Exhibit.
A storage administrator uses Unisphere for VMAX to review the workload for Storage Group mastermgmt_app1. How will storage be allocated for this Storage Group?
