*NOTE:

HP StorageWorks Continuous Access EVA comes complete with an advanced management user interface called Replication Solutions Manager. RSM can optionally be deployed on a general Windows server. Please see the "Hardware and software Prerequisite sections" for more information. RSM user interface automates many of the management functions for data replication between arrays at the source and destination sites. With RSM, configuration and management is now handled through wizards and a job engine that accelerates common Data Replication tasks. Also with the addition of host agents, users can easily identify and manage storage volumes and host volumes depending on their needs. HP Business Copy (local replication) tasks are fully integrated in the Replication Solutions Manager GUI to help users replicate, protect and share data more easily. Other time-saving features include an interactive topology viewer, quick-fill templates for common tasks, integrated wizards and cross array management control of the full EVA product line.

As an option, HP StorageWorks Continuous Access EVA can also be managed and configured using HP StorageWorks Command View. HP Command View EVA provides basic configuration and management control of HP StorageWorks Continuous Access EVA. For more extensive management, automation and HP Business Copy integration options, the use of Replication Solutions Manager and, or CLUI client is recommended.

HP StorageWorks Continuous Access EVA supports a single array having a relationship with multiple other arrays. For example, array (A) has a replicating relationship with both arrays B & C, where A is the destination for data received from B, while A is also the source for data that is replicated to C. Note a copy set still has a one-to-one array relationship. Also note that each relationship supports bi-directional use of the link.

• Fan-in with multi-relationships is a single destination array for two source arrays, not the same data, LUNs, copy set, or DR groups.
• Fan-out with multi-relationships is a single source array with two separate destination arrays, not the same data, LUNs, copy set, or DR groups.

For HP-UX environments HP Metrocluster is a business continuity solution with automatic site failover capabilities. More information on HP Metrocluster can be found at

HP StorageWorks Continuous Access EVA provides the capability to replicate data over direct Fibre Channel. The distances supported over dark fiber are determined by the speed of the dark fiber connection and the technology used to communicate over the dark fiber. Please refer to the HP SAN Design Guide for details on transceiver distance support for different speed FC connections.

HP StorageWorks Continuous Access EVA also supports Wave Division Multiplexing (WDM) optical networks, regardless of manufacturer. WDM provides high bandwidth connectivity of enterprise level SAN over a metropolitan area network via private or public dark fibre optic networks. Remote replication via WDM is ideal when customers already have existing fibre optic cables between the two sites but are unable to install additional cables. WDM maximize the existing fibre optic infrastructure.

Support for Fibre Channel over Internet Protocol enables HP StorageWorks Continuous Access EVA to replicate data across IP networks. Several vendors have been qualified for interoperability with StorageWorks products to encapsulate FC data packets into IP packets. IP data packets are transferred across an Ethernet 10/100 or GbE network. This enables users to take full advantage of their infrastructure already in place and leverage the IP knowledge.
More information on SAN Extensions can be found in the "HP StorageWorks Continuous Access Implementation Guide" available at: http://h18006.www1.hp.com/products/storage/software/conaccesseva/index.html.

• Copy Set (CS): Relationship between a virtual disk on a source EVA and a virtual disk on a destination EVA. Data is copied from the source to the destination. A copy set is uni-directional. The term copy set is only used to reference the connection, or relationship between virtual disks. Actions to create these relationships are executed through the creation of DR groups or by adding a Vdisk to an existing DR group.
• Data Replication Group (DR Group): A collection of one or more copy sets, logically grouped together for data consistency reasons.
• Disk Group: Pool of physical disks from which virtualization is drawing virtual disk storage.
• Destination: EVA with data replication functionality, which acts as the target for a given DR Group.
• Managed Set: Collection of DR Groups that can be failed over all at once by HP StorageWorks Replication Solution Manager and may span multiple HP StorageWorks Continuous Access EVA configurations.
• Multiple Relationships: A single EVA array can have a relationship with other EVA arrays.
• Source: EVA with Data Replication functionality, which acts as the originator for a DR group.
• Virtual Disk (Vdisk): A designated amount of storage space, typically with redundancy, drawn from a pool of physical disks known as a Disk Group. Virtual disks are presented to Hosts as LUNs.

A license (LTU) enables the array to replicate data from a source EVA to a destination EVA storage system array. Without a HP Continuous Access EVA license the data replication features are not available for configuration or utilization on the array. A license key must be purchased in order to enable HP Continuous Access EVA on the VCS/XCS firmware. HP Continuous Access also allows replication between the entire EVA family. In this case, the user would purchase the appropriate LTU based on the array model for each system. You can reference the licensing part numbers in this QuickSpecs in the section titled Ordering Information.

HP Continuous Access EVA licenses are purchased either one of four ways:

1. The first option is a HP StorageWorks Continuous Access EVA3000/5000/4100/6100/8100/4400 1TB entry level license where up to 1TB of data can be replicated using HP Continuous Access EVA software.
2. The second option is a HP StorageWorks Unlimited Capacity use per EVA3000/5000/4100/6100/8100 /4400 license where the only limit to the amount of data that can be replicated is the total amount that the array hardware, controllers and disk drives can actually accommodate. Once purchased, you no longer have to purchase additional capacity licenses to accommodate new capacity growth.
3. The third option is the purchase of an upgrade from 1TB to Unlimited. The Upgrade License provides the same rights as Unlimited Capacity use per EVA license.
4. You may also upgrade from an HP StorageWorks Unlimited Capacity per use license from a) EVA3000/4100 to EVA6100, b) EVA3000/4100 to EVA8100, or c)EVA5000/6100 to EVA8100

NOTES:

1. When ordering a HP Continuous Access EVA license SKU, make sure you plan for current data you intend to replicate plus a full year of growth. Licensing is on a per array basis.
2. HP Replication Solutions Manager is included at no additional charge with the purchase of either HP Business Copy EVA, or HP Continuous Access EVA.
3. HP Continuous Access EVA licenses are not transferable to like, or unlike EVA models. When enabling HP Continuous Access EVA features on an EVA a new license must be purchased, or in some cases an upgrade license may be purchased if upgrading an existing EVA array's model that already has HP Continuous Access enabled.
4. When using HP Continuous Access EVA, each array that is part of the remote replication solution must have the appropriate license. The total licensed capacity for a HP Continuous Access LTU is based on the replicated source volume(s) usable capacity. If the array is also being used as a destination, then the total licensed capacity required would include the destination volume(s) usable capacity.
5. With the new Replication Solutions Manager GUI, both remote replication and local replication features can be managed. For all of these features to be enabled, both HP Continuous Access (remote replication features) and HP Business Copy (local replication features) must be licensed. If any feature is not licensed, the action will fail and be logged in the event pane. Please note that when using the Cascaded Replication feature both a HP Business Copy and an HP Continuous Access license must be installed at the intermediary site where a Snapclone of the data is required.
6. HP Continuous Access EVA monitors the amount of data being replicated as compared to the amount of data permitted to be replicated based on the License-to-use (LTU) capacity. If this threshold is exceeded, a warning event will be issued. The user will be permitted to continue using the HP Continuous Access EVA features and will need to add the appropriate LTU to remain compliant to the End-User-License-Agreement (EULA) and product documentation.
7. Licenses obtained through the Not-For-Resale (NFR) program, temporary licenses, loaner licenses, Instant-on or any other license at no charge are provided strictly for evaluation and demonstration use and cannot be used for data migration (Please see ordering information for data migration part numbers). These licenses do not include support services, may or may not include product documentation and must comply with all terms, conditions and time limits.
   

Example 1: Customer orders an EVA6400 and an EVA8400 and wants to replicate data using HP Continuous Access EVA
Answer: The customer may order a 1TB LTU part number or an Unlimited capacity LTU for each array depending on the amount of data that is to be replicated. Each array has its own set of part numbers and pricing based on the array model .

Example 2: Customer has purchased several HP Continuous Access EVA licenses in excess of 1TB (using an older licensing model), and wants to purchase more capacity to be replicated?
Answer: Simply purchase a HP StorageWorks Continuous Access Upgrade to Unlimited Capacity Use license for EVA model. In doing so, your EVA array is now been upgraded to Unlimited Capacity use per EVA.

Example 3: Customer would like to migrate data from their HP EVA6100 to a new HP EVA8400. The HP EVA8400 will be configured for remote replication with another existing EVA8400 that already has HP Continuous Access licensed.
Answer: The customer must purchase HP Continuous Access EVA Data Migration 7TB 90 Day LTU (TA663A) or HP Continuous Access EVA Data Migration Unlim 90day LTU (TA664A) based on the amount of data that needs to be migrated for the EVA 6100 and either an HP Continuous Access EVA8400 Series 1TB Software License (TA670A) or HP Continuous Access EVA8400 Series Unlimited Software License (TA671A) for the new EVA 8400 based on the capacity requirements.

Example 4: The customer upgrades from EVA 4100 to EVA 6400, can the customer transfer the Continuous Access EVA licenses from EVA 4100 to EVA 6400?
Answer: The Continuous Access EVA software licenses are not transferable. So the customer must purchase a new Continuous Access EVA software license for EVA 6400.

Example 5: The customer upgrades from an EVA 4100 to EVA 6400, can the customer use model upgrade licenses?
Answer: Model upgrade licenses are only supported for within the family or data in place upgrades. So the customer must purchase new Continuous Access EVA software licenses for EVA 6400.

Example 6: The customer upgrades from an EVA4400 1TB Continuous Access EVA to an EVA6400.
Answer: Customer must first purchase the upgrade to unlimited on the EVA4400 then purchase an upgrade from EVA 4400 to EVA6400 LTU. To upgrade between EVA models the customer must have an unlimited license.
