Overview
HP StorageWorks Cluster Extension EVA
HP offers a range of solutions that protect your valuable information against the threat of downtime making your operations resilient regardless of external or internal events. HP business continuity software solutions provide disaster tolerance to keep your corporate information accessible, and available through adverse events. Any amount of system downtime can mean lost productivity, lost revenue, lost customers, and lost opportunities; HP provides proven technologies strategies, and services to reduce your exposure and vulnerability. Defend your mission-critical operations and secure your company's future with HP StorageWorks Cluster Extension. Cluster Extension EVA (CLX EVA) offers protection against application downtime from fault, failure, or site disaster by extending a local cluster between data centers over metropolitan distance. CLX EVA reinstates critical applications at a remote site within minutes after an adverse event and integrates with your open-system clustering software (MS Cluster Service in Windows environments and native clusters on RedHat and SuSe in Linux environments), HP StorageWorks Continuous Access EVA to automate failover and failback between sites. This dual integration enables the cluster service to verify the status of the storage as well as the server cluster; thus allowing the correct failover and failback decisions to be made which minimize downtime, and accelerates recovery - without human intervention. Support for CA enhanced async feature Support for Microsoft Windows Server 2008 R2, Hyper-V Support for Hyper-V Live Migration Support for native clusters on RedHat and SuSe Linux

Accelerated application recovery with minimal transaction loss Disaster tolerant solutions to ensure business continuance and company survival Creation of disaster tolerant copies of your "critical business data"

Product Features

EVA array family support The entire EVA array family is support on either end of the DT configuration. Whether repurposing legacy units or simply adding newer generation units to an existing CLX EVA configuration, both sites are covered. See "Software Support" section for configuration requirements. Protection against transaction data loss Because the application cluster is extended over two sites and the storage is replicated at the second site using synchronous replication methodology, data exists ubiquitously with virtually no difference in the data storage from site A to site B. No-single-point-of-failure solution to increase the availability of company and customer data Determined by the distance and latency requirements for the Continuous Access EVA and cluster server.
Metropolitan distance support Fully Automatic Failover and Failback No server reboot
Automated failover and failback reduces the complexity involved in a disaster recovery situation. It is protection against the risk of downtime, whether planned or unplanned. Disks on the Server on both the primary and secondary sites are recognized during the initial system boot in a CLX EVA environment; therefore LUN presentation and LUN mapping changes are not necessary during failover or failback - for a truly hand-free disaster tolerant solution.
Disaster Tolerance (DT) Cluster Extension is the key that unlocks the critical difference between disaster recovery (DR) and disaster vs. Disaster Recovery (DR) tolerance (DT). Most DR products pledge that operations will resume following downtime (typically unexpected). CLX EVA delivers DT - control over the possibility of downtime itself. This control No Single Point of failure Supreme redundancy: identical configuration of established SAN infrastructure redundancies are implemented on site B. Synchronous mode Support Continuous Access EVA offers synchronous data transfer mode between arrays and host. Synchronous data transfers offer the highest levels of data protection. With synchronous operations, both the source and destination copies are identical and concurrent at all times. Synchronous mirroring ensures that data copies are identical, to prevent critical data loss in the event of a failure or disaster. In this mode, data is written simultaneously to the mirrored cache of the local storage system and the remote storage system, in real time, before the application I/O is completed, thus ensuring the highest possible data consistency. Synchronous replication is appropriate when exact consistency is critical to the business application.

MSCS Majority Node Set CLX EVA Windows uses the Microsoft Majority Node Set (MNS) and Microsoft File Share Witness (FSW) quorum feature that is available in Windows from MS Windows2003. These quorum models provide Integration protection against split-brain situations without the single point of failure of a traditional Quorum disk. Split Brain syndrome occurs when the servers at one site of the stretched cluster lose all connection with the servers at the other site and the servers at each site form independent clusters. The serious consequence of the split-brain is corruption of business data since data will no longer be consistent.

XP Continuous Access is an irreplaceable component for protecting any business, yours especially. XP Continuous Access is sold by utilized capacity.

Synchronous replication is appropriate when exact consistency is critical to the business application. XP Continuous Access Asynchronous offers data transfers between storage arrays with up to 100ms oneway latency between gateways. The advantage of asynchronous replication is that the host to storage I/O is not impacted by the latency between gateways, resulting in faster write completion back to the host. Un-transmitted write I/O's are stored in the primary array cache and transmitted in bulk to the remote array. The array maintain write order using sequence numbers for each write I/O and will always have consistent data on the remote array, even if some transactions were lost during the disaster. This may be beneficial or preferred by long distance remote replication configurations. XP Continuous Access Journal improves the async replication method, by storing un-transmitted write I/O in a disk based journal device instead of the array cache, releasing valuable resource to other operations in the array. The use of Journal device provide better protection during short link failures and can maintain journal operations during High I/O load to the primary array. Write order is maintained by using sequence numbers for each write I/O and data consistency is always guaranteed on the remote array. Implementing Synchronous, Asynchronous or Journal replication is dependent on the specific replication environments and the customer requirements. Replication method can be assigned at the DR group level, and using a mixture of replication methods in the same environment is allowed.
