IBM System Storage™ N series – Unified Storage Solutions RAID-DP® P DP § Traditional single-parity RAID technology offers protection from a single failed disk drive. § The expectation is that no other disk fails nor uncorrectable bit errors not occur during a read operation while reconstruction of the failed disk is still in progress. § If either event occurs during reconstruction, then some or all data contained in the RAID array or volume could be lost. With modern larger disk media, the likelihood of an uncorrectable bit error is fairly high, since disk capacities have increased but bit error rates have stayed the same. § The ability of traditional single-parity RAID to protect data is being stretched beyond its limits. § Protects better than single-parity RAID or RAID 0+1 § Designed to survive all 2 -disk failure scenarios § Essential for SATA drives but also applicable to FC drives § Breakthrough innovation: USENIX Best Paper in 2004 § No performance penalty for industry-leading protection Clustered Failover (CFO) § Automatic failover with notification provides continuous data availability for an unavailable storage controller and notifies administrator of failover. Application Cluster with N series clustering § Manual failover and giveback enables planned maintenance on a storage controller without impacting data availability N series Disk § Transparent failover: end users are not impacted by a failover; clients continue to access data the same way after a failover. § Active/active configuration; both clustered controllers are doing useful work; no resources sit idle waiting for a failover to occur Volumes 61 IBM System Storage N series Overview October 23, 2007 © 2007 IBM Corporation

Validator detects and prevents potential corruptions of Oracle data before they happen. § Oracle system assigns a unique value to each write request based on the sum of the data and sends the data set down the I/O path to the N series system. Upon receipt, Snap. Validator calculates the sum of the data and compares it to the Oracle value. § If these values match, the system writes the information to disk and reports a successful write. § If the identifiers do not match, the system prevents the data corruption and produces an alert. § Snap. Validator meets Oracle HARD (Hardware Assisted Resilient Data) initiative and provides the highest possible level of protection for Oracle data. October 23, 2007 © 2007 IBM Corporation
