A regional market leader in direct financial services run several call centers across the United States and is opening a number of new call centers in the near future. The client uses Windows XP on dedicated workstations. The IT infrastructure consists of numerous HP ProLiant DL 360 G5 and HP ProLiant DL380 G6 servers running VMware ESX or SUSE Linux for the database server, direct attached storage, and HP Ultimatum tape drives. They want to consolidate the infrastructure.
Which drawback of his environment can be eliminated when designing an HP StoreVirtual 4000 Storage solution?
A. Unexpected downtime caused by a site failure
B. Performance bottlenecks caused by mixed workloads
C. Inconsistent Oracle data caused by array snapshots
D. Capacity bottlenecks caused by duplicated data blocks
Correct Answer: B
Explanation/Reference:
Explanation:
SmartClone technology is based on the space-efficient LeftHand Thin Provisioning architecture, and the volume clones can be used without limitation along with all other LeftHand OS features like Network RAID, Thin Provisioning, Snapshot, and Remote Copy. The feature works by taking any volume or snapshot and making one or many clones in an instant. The cloning function makes a permanent, read/write volume on the array, pointing back to the original volume’s blocks instead of duplicating the blocks. By managing each clone as a pervasive volume, SmartClone eliminates any requirement for a volume, snapshot, or any of its predecessors to exist after the clone has been created, and also eliminates the need to run de- duplication software, because there are no duplicate blocks. The clone shares the original volume’s blocks and uses copyon-write semantics. SmartClone technology reduces storage costs and increases overall storage efficiency.
Administrators can store "gold-master" system images on the array for virtual desktop and boot- from-SAN implementations, and quickly provision test environments using real production data. To simplify management, administrators can view all of the relationships between clones, volumes, and snapshots graphically in the Control Management Console. http://h18006.www1.hp.com/products/quickspecs/13254_div/13254_div.pdf
