单选题 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?()
Change the stripe size on the RAID controller
Change the stripe size to 1024K on the RAID controller
Change the stripe size on the RAID controller for the first array
Change the stripe size on the RAID controller for the second array
单选题 A customer is running a number of HP Intel servers within an IBM management environment. The HP Insight Manager agent is already installed, but they do not want to install the Director agent because of potential conflicts. Into which system are the MIB files compiled?()
On the HP managed server
On the IBM Director server
On the IBM Director Jet database
In the IBM Director database
单选题 A company wants a solution to consolidate their storage using the DS4000 series and implement a disaster recovery solution across two data centers linked by fibre to duplicate the production environment.The customer requires a solution with the least amount of system administration. Which configuration would provide the best solution?()
Implement one DS4400 at each location connected to the fibre link and use Remote Volume Mirror (RVM).
Implement a DS4400 at each location using FlashCopy option and use host based replication to synchronize the sites.
Implement a switched fabric using redundant SAN switches with a DS4300 using RVM option at each location.
Implement a switched fabric using SAN switches connected via ISL with a DS4300 using RVM option at each location.
多选题 Which TWO of the following are required to use the hot-swap memory feature of the x445 while being operating system independent?()

Redundant bit steering must be enabled in the BIOS.
DIMMs must be the same size and speed as the DIMMs being replaced.
Memory Mirroring must be enabled in the operating system.
DIMMs can be of same size or larger or same speed or faster.
单选题 A customer uses an IBM xSeries x366. They experienced downtime when the NIC failed earlier this year. Their Windows 2003 server needs to be accessible all the time, at the highest speed possible. Two adapters are currently installed in the x366. Which of the following is the procedure to obtain the best performance and ensure network functionality in case of NIC failure?()
Install four NICs and configure load balancing adapter teaming.
Install four NICs and configure adapter failover teaming.
Install seven NICs and configure load balancing adapter teaming.
Install one extra NIC to team with the internal adapter and configure failover teaming.
单选题 A small bio-technical company is interested in implementing a 32-node Linux cluster. They developed their own software that allows all of the nodes to work on the same problem at the same time. The application requires messages to be passed between the nodes. Each node will require access to a shared storage pool of around 500GB. To identify throughput requirements for the storage pool, which of the following is the most appropriate question to ask?()
Is high availability required?
Which network protocols are going to be used?
What are the expected I/O’s per second to the storage?
To what network infrastructure is the storage pool connected?
