Question 51:
HP 3PAR Remote Copy is supported in synchronous and asynchronous periodic modes. Which protocol is supported only by asynchronous periodic replication?
A. FCIP
B. iSCSI
C. FCoE
D. FC
Correct Answer: A
http://h20195.www2.hp.com/v2/GetPDF.aspx%2F4AA3-3053ENW.pdf Multi-protocol support With Native IP as well as Fibre Channel (FC) support, HP 3PAR Remote Copy Software delivers out-of-the-box connectivity over your IP network, enabling you to replicate data more cost-effectively by leveraging your existing infrastructure. Achieve robust DR without the expensive converters and management of a separate, special-purpose infrastructure.
Connectivity choices HP 3PAR Remote Copy offers two native methods of connectivity in order to satisfy the varying business or technical needs of users: traditional Fibre Channel and TCP/IP over Gigabit Ethernet. With suitable switches, Fibre Channel over IP(FCIP) is also supported, allowing asynchronous periodic Remote Copy over longer distances without introducing GigabitEthernet into the SAN.
A customer has a small computer room with an existing HP BladeSystem c-Class Enclosure. The customer has 10 U of free space in their existing rack and would like to add an enterprise-class storage system. To keep costs down the
customer would like a Flat SAN and a storage system that can be scaled up in the future into their existing rack space.
What should you recommend?
A. HP 3PAR StoreServ 10000
B. HP 3PAR StoreServ 7000
C. HP StoreVirtual 4130 FC
D. HP StoreAll 9300
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.

Question 54:
A retail customer recently experienced a major flood in the area of their data center and lost some critical financial data. They are now planning to purchase an HP StoreVirtual multi-site configuration and rent collocation space in another city. As a part of the proposal, which component of the HP StoreVirtual architecture must be implemented to support automatic quorum management across the two sites?

Question 55:
A current customer has an older HP 3PAR StoreServ F400 running InForm OS 2.3.1 in a pre- production data center and is facing a new schedule for scaling out the application into production. The scale out will require twice the capacity and three times the performance to handle the initial workload. You design a new high performance HP 3PAR StoreServ 7400 with 64 SSDs to meet the demand of the new application. The customer has already tested new application servers attached to the F400.Due to competitive issues, the customer needs to move into production quickly and with minimal disruption. Which solutions should you include to help ensure customer success? (Select two.)
A. HP MPX200 Appliance to facilitate automatic storage migration from the older 3PAR array with minimal disruption
B. HP 3PAR StoreServ Thin Conversion to reduce the storage requirement on the new array.
C. HP 3PAR StoreServ Peer Motion to allow for non-disruptive storage movement to the new array
D. HP 3PAR StoreServ Temporary Remote Copy License for data migration to the new array as easily as possible
E. HP 3PAR StoreServ Data Migration services to assist with populating the new array with production data
Correct Answer: BC

Question 58:
Your customer has an existing HP StoreVirtual P4500 G2 multi-site SAN, which has become I/O constrained. They want to implement a new higher performance tier into the existing management group. Which Peer Motion method provides the ability to dynamically rebalance data volumes to the higher performance tier?
Peer Motion on HP StoreVirtual Storage: Volume migration Peer Motion on HP StoreVirtual Storage allows a system administrator to move an HP StoreVirtual volume from one cluster to another, online, without having to reconfigure the host or applications. This is done by simply editing the properties of a volume, selecting the Advanced tab, and choosing a new cluster from the cluster drop-down box. The blocks that make up the volume on the original cluster will begin to migrate to the new cluster, and the LeftHand OS will automatically redirect and proxy requests for blocks to the proper cluster as the data migration is underway. When the migration is complete the iSCSI sessions to the new cluster from the host are automatically restored (assuming the new cluster's virtual IP address has been added to the iSCSI configuration of the host server). A typical use case for Peer Motion could be a volume that contains data for an application that has increasing performance needs. If The volume started out on an MDL SAS cluster, a storage administrator could use Peer Motion to move the volume to a SAS-based cluster. If the volume is on a SAS cluster, the storage administrator could choose to add more nodes to the cluster to provide more performance for the volume, or they could choose to move the volume to an even higher performing tier, such as an SSD-based cluster.
Peer Motion on HP StoreVirtual Storage: Cluster swap The virtualization of storage within an HP StoreVirtual cluster means that the rules about data being tied to physical hardware resources no longer applies. This virtualization allows volumes to be moved dynamically between different physical hardware clusters, and also allows for a feature called cluster swap--the ability to remove existing storage nodes from a cluster and replace them with new storage nodes, online,
with no loss of data or data availability.
In one operation, data from the old storage nodes is moved to the new storage nodes, and all IO is properly directed to the correct node. Upgrading to newer, faster, or larger storage nodes does not require any downtime, providing a clear, well-defined strategy for future expansion and growth. As an example, a customer might start out with a cluster of 8 drive systems. As the customer adds more applications and workload to the cluster, they could reach the Performance or capacity limit of the nodes. They could easily migrate to nodes with 12 or more drives to increase capacity and performance, without having to bring any applications offline.
Question 59:
During a recent customer presentation, a question was raised regarding the HP StoreVirtual cluster running out of storage space. In reviewing the customer needs. The recommendation was to add a new HP StoreVirtual cluster. How can the customer move data from the existing HP P4000 cluster to the new HP StoreVirtual cluster?
A customer is planning to move four HP BladeSystem c7000s to another location. The Onboard Administrator firmware is at the current version. The disk drives and Virtual Connect Flex-10 modules must be removed before shipment. Which design impact must be considered if the Virtual Connect Flex-10 modules are not reinstalled in their original locations?
A. The Virtual Connect configurations on the installed chassis will be overwritten.
B. The blade chassis will be reset to factory defaults.
C. The original Virtual Connect configurations will remain intact.
D. All server network and SAN connections will be disabled.
Connecting multiple enclosures Virtual Connect supports the connection of up to four c7000 enclosures, which can reduce the number of network connections per rack and also enables a single VC Manager to control multiple enclosures. A single set of cables can be used to carry all external Ethernet traffic from a single rack. Multiple enclosure support enables up to four c7000 enclosures to be managed within a single Virtual Connect domain.
