Question 4
Company.com is planning to implement a new service, and needs to deploy two servers in a active/passive cluster maintaining a large repository of data. This data will include three sets of data: SET 1:Stream type data:3MB Files on average :many thousands SET 2:Large file data:200KB Files on average: many millions SET 3:Small file data: 15 KB Files on average:hundereds of millions The application developer is writing code that is specific to an implementation of clustering that requires block level access. Which solution does not degrade performance?

Question 9
A client is consolidating a database server into an existing SAN attached array with 73 GB drives and a default LUN size of 8.8 GB. The server currently uses O/S based volume management on 9 GB LUNs carved from 36 GB drives in a direct attached disk array. The array is connected using two 100 MB/s FC ports. The file systems are set at a default blocksize of 2048. Which would be the most important to address in your design?
A.
Adapt to standard LUN sizes, paying migration penalities
B.
Upgrade connectivity from 100 to 200 GB, incurring upgrade cost
C.
Account for change in access density from 36 GB to 73 GB drive
D.
Determine capacity/performance impact of file system parameters

Question 11
You notice, from continually monitoring a SAN arry, that an array has a number of soft SCSI bus error. You trace the errors back to a single drive using a vendor's event tool. Which two would correct this? (Choose two)
A.
You should pull the drive out immediately and replace it to prevent data corruption on the RAID set.
B.
Soft SCSI bus errors can be safely ignored as they do not actually denote any service requirements.
C.
You should research the error to determine the impact and proper response including the vendor in these discussions
D.
Review the logs from the array to identify if there is a pattern of large numbers of these SCSI errors. A large number of these SCSI bus errors may denote a predictive failure.
