What would you recommend to meet the implied requirements?
You work as a design specialist at Certkiller .com. Certkiller .com wants to extend their tape SAN to a third party remote vaulting location through a public network. The backup content is 99% image files, using the *jpg format. What would you recommend to meet the implied requirements?
What would be your primary design concerns?
You work as a design specialist at Certkiller .com. Certkiller .com has a four-member cluster that contains nine months of cellular/mobile phone provider data. The system controls network authorization, performs fraud analysis, produces reports and final billing feeds. Workloads include incoming data from cell towers and real-time account recalculation results. Network traffic continues to increase.
Mirrored BCVs and SRDF protect the data.
1. Supporting storage is spread across six Symmetrix 8430s and five Symmetrix 8530s using 36 G and 73 G drives, respectively.
2. 35.2 G meta-volumes used in a double-stripped 4×768 K configuration.
3. Cell related IOPS during peak use hours range from 12 to 30 K per array. Marketing sold consolidation to a single DXM 3000 with 146G drives using RAID 5 to reduce TCO and provide 18 months of growth.

What is the minimum number of physical mirrored drives (RAID 1) necessary to satisfy meet these requirements?
You work as a design specialist at Certkiller .com. Certkiller .com plans to implement a new application. The application’s requires are as follows:
1. 85 IOPS sustained throughput per LUN
2. 2.19 Terabytes or storage
3. 4 HBAs
4. 40 LUNs
5. DMX Storage Array
Assume each physical 146 GB drive can sustain 170 IOPS, and that the application will perform approximately 25% writes and 75% reads.
What is the minimum number of physical mirrored drives (RAID 1) necessary to satisfy meet these requirements?
What is the probable cause of this problem?
You work as the Storage Administrator (SA) at Certkiller .com. Certkiller .com has an MX Exchange environment. Users have been complaining about poor performance. Upon investigation, you discover that the system is performing two reads for every transaction.

What is the primary risk to the QAT instance during upgrade tests?
You work as a design specialist at Certkiller .com. Certkiller .com uses SAN Copy from their production system (PRD) to both Quality Assurance and Test (QAT) and Development (DEV) instances. The PRD instance resides on DMX while both QAT and DEV instances reside on CLARiiON ATA.
The PRD instance is 27 TB and is backed up from BCVs. Backups from SnapView support both QAT and DEV instances. The QAT instance is refreshed monthly but the DEV instance is refreshed quarterly because it is a time consuming process. Certkiller .com plans to upgrade the system. You need to run upgrade tests.
