A 300 GB database needs two local replicas for reporting

A 300 GB database needs two local replicas for reporting and backup. There are constraints in provisioning full capacity for the replicas. It has been determined that the database has been configured on 15 disks, and the daily rate of change in the database is approximately 25 percent. You need to configure two pointer-based replicas for the database. Describe how much capacity you would allocate...

A company is considering implementing storage. They do not have

A company is considering implementing storage. They do not have a current storage infrastructure to use, but they have a network that gives them good performance. Discuss whether native or bridged iSCSI should be used and explain your recommendation.

A host generates 8,000 I/Os at peak utilization with an average I/O size of 32 KB. The response time is currently measured at an average of 12 ms during peak utilizations. When synchronous replication is implemented with a Fibre Channel link to a remote site, what is the response time experienced by the host if the network latency is 6 ms per I/O?

A performance problem has been reported on a database. Monitorin

A performance problem has been reported on a database. Monitoring confirms that at 12:00 AM, a problem surfaced, and access to the database is severely affected until 3:00 PM every day. This time slot is critical for business operations and an investigation has been launched. A reporting process that starts at 12:00 PM contends for database resources and constrains the environment. What...
