A company installed a new server to manage its electronic image storage. They have two distinct image sizes： 2KB and 16KB. Two distinct arrays are created on a ServeRAID adapter. The first array will store all of the 2KB images， and the second array will store all the 16KB images. The RAID stripe size was left at the default size of 8KB. After installation， a performance problem is identified. According to performance monitoring， 80% of the images are 16KB. Which of the following will best optimize performance？（）

A.Change the stripe size on the RAID controller
B.Change the stripe size to 1024K on the RAID controller
C.Change the stripe size on the RAID controller for the first array
D.Change the stripe size on the RAID controller for the second array

A customer wants to hold all enterprise data on their DS4000 system. Several servers were added after they purchased another company. The servers that have to be run are：
（1）An Oracle database running on a HP-UX server
（2）Several virtual machines running on VMWare ESX server
（3）A Microsoft cluster running Exchange 2000 server
Which of these new servers can be integrated with the DS4000？（）

A.DS4000 storage does not support HP-UX， so the HP-UX server cannot be integrated.All other new servers can be used.
B.An Exchange cluster needs local disks， so the DS4000 cannot be used for this.All other new servers can be used.
C.When equipped with proper HBA’s and subsystem device drivers， all new servers can operate with the DS4000 storage device.
D.VMWare ESX can use the DS4000 storage； however， the virtual machines running in it will not have access to this storage other than via a virtual disk.All other new servers can be used.
