In many cases, the growth pattern for a storage installation is difficult or impossible to predict. To accommodate this unpredictability, the SAN architect should allow for growth within a predefined design that _____.
A. uses the cascaded switch topology as the initial installation
B. is a subset of the mesh for a smaller configuration
C. uses the ring switch topology as the initial installation
D. uses the initial installation as a subset of a larger pre-designed configuration
A customer is testing storage array replication with two storage systems in their data center. The arrays are connected with fiber optic cables that are a total of 30 meters in length. The replication mode is changed from synchronous to asynchronous. How does this affect replication performance in this case?
A. Asynchronous mode replication is much faster than synchronous mode.
B. Asynchronous mode replication is about the same as synchronous mode.
C. Synchronous mode replication is much faster than asynchronous mode.
D. Synchronous mode replication is slightly faster than asynchronous mode
What three results of a storage assessment are useful in determining the cross-sectional bandwidth and topology requirement in a SAN design? (Choose three.)
A. application I/O data rates
B. number of application users
C. total storage capacity
D. backup throughput
E. volume usage statistics
F. application data access patterns
For HP, what is Data Availability Level 4 in a SAN?
A. maximum connectivity using a single non-meshed fabric, a single server and single storage paths
B. designs with more than one ISL between switches and the addition of multiple data paths between servers and storage connecting into one fabric
C. designs with more than one ISL between switches that provide the benefit of fabric resiliency against link failure
D. designs with dual fabrics using multiple physically separate fabrics, multi-path designs
What is SAN event management?
A. monitoring IP network resources through the same Ethernet infrastructure
B. monitoring external system events when a triggering condition occurs
C. monitoring storage resources to ensure availability per business requirements
D. monitoring the planning, acquisition, and optimal usage of SAN resources
