Which alternative solution will minimize contention when reading this point-in-time copy?
TimeFinder/Snap is being used as a point-in-time database reporting solution on a high-performance Oracle 11g database. During the time the snaps are activated, the 7 x 24 Oracle application experiences slow response times.
Which alternative solution will minimize contention when reading this point-in-time copy?
Which type of I/O activity could cause this situation?
The front-end requests (FE Reqs/sec) consistently exceed the host IOs/sec on the EMC Symmetrix VMAX array shown in the exhibit.
Which type of I/O activity could cause this situation?
Will the current settings allow Symmetrix VMAX storage to be successfully presented to a VMware vSphere ESXi s
The exhibit shows the current port flag settings for a Symmetrix VMAX FA port.
Will the current settings allow Symmetrix VMAX storage to be successfully presented to a VMware vSphere ESXi server and why?
What is the connectivity recommendation when an ESXi server is connected to a one-engine Symmetrix VMAX array
Refer to the Exhibit.
What is the connectivity recommendation when an ESXi server is connected to a one-engine Symmetrix VMAX array over an FC SAN?
How should SRDF be configured between Sites B and C?
Refer to the Exhibit.
A company has three data centers and has decided to protect its data using SRDF. The replication design must ensure there will be no data loss if Site A fails. All data centers are within 200 km of each other. Either Site B or Site C should be able to take over as production sites in the event of the failure of Site A. SRDF/S is used between Sites A and B.
How should SRDF be configured between Sites B and C?
What could be the cause?
The back-end IOs/sec (BE IOS/sec) consistently exceed the host IOs/sec on the EMC Symmetrix VMAX array shown in the exhibit.
What could be the cause?
What is used to determine the invalid tracks that must be moved from Site A to Site C?
Refer to the Exhibit.
In a Cascaded SRDF/Star environment, Site B fails. The surviving sites are reconfigured to enable remote data protection.
What is used to determine the invalid tracks that must be moved from Site A to Site C?
What is one of the necessary conditions before an MSC cycle switch is performed at Site B?
A composite group spanning two Symmetrix arrays is set up to run SRDF/Star using Cascaded SRDF as shown in the exhibit.
What is one of the necessary conditions before an MSC cycle switch is performed at Site B?
Which action would reconfigure the RDF device relationships such that the workload site is located at Site B a
Refer to the Exhibit.
An SRDF/Star configuration has a workload running at Site A. A symstar halt command is executed at the workload site (Site A). Which action would reconfigure the RDF device relationships such that the workload site is located at Site B and both RDF targets are in the disconnected state?
