Cyclic redundancy check (CRC)

Cyclic redundancy checking (CRC) is an enhanced checksum function. When this option is selected, CRC checksums are written to the media during backup. CRC checks allow you to verify the media after the backup. Data Protector recalculates the CRC during a restore and compares it to the CRC on the medium. It is also used while verifying and copying the media. This option can be specified for backup, object copy, and object consolidation operations. The default

value is OFF. Figure 49 shows the default configuration parameters for Ultrium tape drives. CRC checking was OFF.

http://www.manualslib.com/manual/484560/Hewlett-Packard-D2d.html?page=7 Key factors for performance considerations with deduplication:

The inline nature of the deduplication process means that there will always be some performance trade-off for the benefits of increased disk space utilization.

With each Virtual Library or NAS Share created there is an associated dedicated deduplication deduplication across all backups is required, this will only happen if a single store. If Global virtual library or NAS share is configured and all

backups are sent to it. The best deduplication ratio will be achieved by configuring a minimum number of libraries/shares. Best performance will be gained by configuring a larger number of libraries/shares and optimising for individual

deduplication store complexity. If servers with lots of similar data are to be backed up, a higher deduplication ratio can be achieved by backing them all up to the same library/share. If servers contain dissimilar data types, the best

deduplication ratio/performance compromise will be achieved by grouping servers with similar data types together into their own dedicated libraries/shares. For example, a requirement to back up a set of exchange servers, SQL database

servers, file servers and application servers would be best served by creating four virtual libraries or NAS shares; one for each server set.

When restoring data from a deduplicating device it must reconstruct the original un-deduplicated data stream from all of the data chunks. This can result in lower performance than that of the backup. Full backup jobs will result in higher

deduplication ratios and better restore performance (because only one piece of media is needed for a full restore). Incremental and differential backups will not deduplicate as well

Overview HP Virtual Connect Flex-10 10Gb Ethernet Module for c-Class BladeSystem

Simplify and make your data center change-ready. The HP Virtual Connect Flex-10 10Gb Ethernet Module for the c-Class BladeSystem is the simplest, most flexible connection to your networks. The Virtual Connect Flex-10 Ethernet Module is a new class of blade interconnect that simplifies server connections by cleanly separating the server enclosure from LAN, simplifies networks by reducing cables without adding switches to manage Virtual Connect wire-once connection management allows you to change servers in just minutes, not days, and tailors network connections and speeds based on application needs. HP Flex-10 technology significantly reduces infrastructure costs by increasing the number of NICs per connection without adding extra blade I/O modules, and reducing cabling uplinks to the data center network. The HP Virtual Connect Flex-10 10Gb Ethernet Module for c-Class BladeSystem is an innovative, new class of integrated interconnects from HP.

Correct Answer: B

Flat SAN HP Virtual Connect for 3PAR with Flat SAN technology In virtual and cloud data centers today, up to 80% of the network traffic is server-to-server and server-tostorage. Legacy, multi-tier fibre-channel network architectures require a complex web of network cards, interconnects, cables, and switches in order to keep pace with this changing traffic. This approach creates performance bottlenecks and drives higher costs and complexity to build, maintain and secure at scale.

Correct Answer: BD

Fabric zoning controls which FC end-devices have access to each other on the fabric. Zoning also isolates the host and HP 3PAR StoreServ Storage ports from Registered State Change Notifications (RSCNs) that are irrelevant to these ports

When changing an existing host persona from 6 to 11, a host reboot is required tor the change to take effect. This is an offline process. See "Configuring ESX/ESXi Multipathing for Round Robin via SATP PSP" (page 42) for the detailed procedure, as the host persona change should coincide with changing the SATP rules on the host as well.
