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?
What is the connectivity recommendation when an ESXi server is connected to a two-engine Symmetrix VMAX array
Refer to the Exhibit.
What is the connectivity recommendation when an ESXi server is connected to a two-engine Symmetrix VMAX array over an FC SAN?
What is an advantage of SRDF/EDP over other methods of SRDF protection?
Refer to the Exhibit.
A pair of Symmetrix VMAX arrays are running SRDF/A. For regulatory reasons, the business wants to implement a third data center. They are proposing to locate production at Site A, a nearby SRDF target at Site B, and a remote SRDF target at Site C.
What is an advantage of SRDF/EDP over other methods of SRDF protection?
Which state must a SRDF/Star configuration be in before the symstar enable command can be issued?
The exhibit shows four excerpts from the SRDF/Star query output in four different system states.
Which state must a SRDF/Star configuration be in before the symstar enable command can be issued?
What is the cause for this behavior?
The workload site in a concurrent Star configuration experienced a disaster. In the course of recovering from the disaster, it is discovered that the RDF pair configuration of the devices between the workload and synchronous target sites is marked as “Duplicate” as shown in the exhibit.
What is the cause for this behavior?
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?
