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?
What is the default HTTPS port used to connect to Unisphere for VMAX?
What is a requirement before a port can be disassociated from an FA emulation on a VMAX3?
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?
Which database does Unisphere for VMAX 8.0 use for Performance Analyzer?
Which SRDF remote replication licenses are available with VMAX3?
A customer has been using a VMAX3 array for the past three months. They now want to add additional capacity to this array. Which files does VMAX Sizer need to process this request?
From an application perspective, what should be done prior to performing an SRDF failback 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.
Which SRDF action is required?
You are in a meeting with a customer discussing virtual provisioning on VMAX3 arrays. The customer wants information on Storage Resource Pool allocation management.
What is the basis for the allocation of new extents to a device?
You have configured Open Replicator between a new VMAX3 array and a VMAX. A host is connected to the VMAX3 array and a control device is configured to pull data from a remote device on the VMAX. You want the host to be able to access data on the control device while the data is being pulled from the remote device.
What will cause writes to the control device to be propagated back to the remote device?
What does the BCSD Write Load Adjustment Factor account for when designing SRDF solutions?
Which types of authentication are supported by Unisphere for VMAX?
How does the VMAX3 Platinum Service Level Objective (SLO) differ from the Optimized Service Level Objective?
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?
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?
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?
What is the benefit of the Link Capacity Adjustment Scheme in an SRDF deployment over a SONET circuit?
The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storage Group containing 10 devices. An application is actively performing read and write I/Os to these devices. Allocation for the SRP reaches 85%.
What will happen to the snapshot?
What is the best practice for adding Flash drives, per engine, on a VMAX3?
