A prospective customer has presented you with multiple applications. All applications have high write activity levels and unpredictable growth patterns. The applications are currently hosted on direct-attached storage in a RAID 1 configuration. They are concerned with making too many changes at one time in their environment.
The prospect has asked you to justify your recommendation of RAID 1/0 on the CLARiiON configuration you are proposing. How do you respond to the request?
A. RAID 1 is less flexible for growing LUNs than RAID 1/0
B. RAID 1 is unavailable in currentCLARiiON configurations
C. RAID 1 LUNs are unable to utilize write cache
D. RAID 1 has a higher write penalty than RAID 1/0
ABC.com would like to create a large pool of “scratch space” disk for their development environment. They are considering using high-capacity SATA drives in a RAID 5 configuration on their CLARiiON array. General performance is not an issue. However, the customer does not want to experience long periods of degraded performance in the case of RAID rebuilds.
Which CLARiiON feature will help the customer prevent this problem?
A. Proactive Hot Sparing
B. Quality of Service Manager
C. Asymmetric Logical Unit Access
D. Vault Load from Peer
ABC.com plans to roll out several experimental large-scale host clusters with low-cost blades for computationally intensive workloads. All IS operations are in a single data center (50 m x 40 m). They use direct-attached storage on all hosts. For better manageability of storage, they are considering a SAN infrastructure with CLARiiON storage (CX3-40s). Preliminary design calls for 200 server blades. Cost and performance are both critical considerations, but high availability is not. Your initial design has single-pathed FC connectivity to each host. Under sustained load, each server blade can sustain up to 4,000 IOPS at 16 KB per I/O. Which additional information do you need before you can attempt a preliminary, high-level SAN design for this environment?
A. Server model/make, OS type and revision, clustering software
B. Breakdown of I/O traffic by customer application
C. Customer’s current disaster recovery strategy
D. Expected cache hit rates on the storage arrays

D. For RAID 5, 43 disks; for RAID 1/0, 28 disks
During a proof of concept, ABC.com who is using a CLARiiON array with four Windows servers notices I/O performance problems on a specific server. Looking at Navisphere Analyzer data for the LUNs in question and comparing the statistics with the System Monitor (PerfMon) I/O counters for the same Windows physical disks, the I/O statistics in Navisphere Analyzer are significantly higher than the System Monitor shows. What is the likely reason for this performance issue?
A. Windows file systems were not aligned on LUNs withdiskpar or diskpart
B. CLARiiON Write Cache has been disabled on the affected LUNs
C. Windows file system caching is interfering withCLARiiON caching
D. CLARiiON cache watermark has been reached and is destaging
ABC.com’s storage environment is organized into four single-director fabrics. The directors are MDS-9509s with 64 switch ports in each. No more than 70% of available ports are in use.
The customer needs hosts in each fabric to access storage in the other three fabrics. It is acceptable for host-to-storage traffic to traverse up to one hop.
What is the least disruptive SAN solution that you should consider?
A. ISLs between adjacent directors to create a partial mesh
B. Convert to core/edge single fabric, isolating all storage to the core director
C. ISLs between adjacent directors to create a partial mesh and enabletrunking
D. ISLs between all directors to create a full mesh
ABC.com currently has a large storage install base with many hosts. A large number of the hosts allocated their storage several years ago and have poor utilization rates. The customer has engaged EMC to design a new storage solution to replace their current storage.

A. Compatible Flash
B. SATA II drives
C. Virtual Provisioning
D. Virtual LUN technology

B. A replicaCelerra LUN is for backup only
C. A replicaCelerra LUN is read-only
D. A replicaCelerra LUN is not accessible for this purpose
ABC.com has implemented a second Brocade director into their environment. They have moved several hosts and one of their two storage arrays onto the new director. When a large batch cycle was run, the customer experienced queuing on the directors when previously there was none.
The customer discovered the following during their analysis of the issue. The hosts running the batch cycle used storage from both arrays.
The only LUNs having problems came from the array attached to the new director. When the batch process was re-run with all LUNs made available through the original director, no problems
