Which factor will affect the customer’s application response times?

A customer has a dedicated network link between a primary and a backup site. The link is rated at 45 Mb/s and has a roundtrip latency of 7 ms. There are four routers and no hubs between the sites. The peak write bandwidth for the customer’s applications is 4 MB/s. They are planning to use MirrorView/S between the sites.

What is the most efficient and least disruptive SAN solution that would meet this need?

A customer’s storage environment is organized into four singledirector fabrics, one each for the Engineering, Marketing, Sales, and Finance divisions. The directors are MDS9509s populated with several switch modules providing 64 switch ports in each director.
Hosts and storage frames connect to each fabric with no more than 70% of available ports in use.
There is complete isolation between the four SAN islands.
With the planned rollout of new crossfunctional applications, the customer needs hosts in each fabric to access storage in the other three fabrics. It is acceptable for hosttostorage traffic to traverse up to two hops.

What is the best method to achieve the desired objectives?

A customer owns a CX340 SAN for their Microsoft application environment. In the course of a SnapView implementation, you discover that the Microsoft file systems are misaligned on the production LUNs. The file systems need to be aligned prior to implementing SnapView for these hosts. Host downtime needs to be kept to a minimum.

Based on the information you have gathered, which solution should you recommend?

A manufacturing customer has decided to consolidate storage onto a CLARiiON. The customer uses a mix of Windows and UNIX workstations during the product design process. One of the customer’s goals is to use pointintime copies of data to make backups easier. In addition, they would like to have the ability to use the pointintime copies to perform a fast recovery in the event of accidental file deletion. The cost of the solution is important.
Your survey of the environment shows that the read/write ratio of the application is 3:1. The application appears to be insensitive to disk response times.
