The challenge all RAID vendors face: the non-correctable error rate Industry-wide trend As disk drive sizes get larger, the bit error rates increase (per drive) Non-correctable error rate is uncomfortably close to bits read during reconstruction Bits per RAID Group Assumes 8-drive (7+1) RAID group 1.0E+16 1.0E+15 Danger Zone 1.0E+14 1.0E+13 1.0E+12 1% - FC FC: 1 bit in 1.0E+15 bits 10% - ATA ATA: 1 bit in 1.0E+14 bits 38 1.0E+11 Error Rates Typical error rates 1.0E+10 1.0E+09 IBM System Storage N series Overview 36GB 73GB 147GB 250GB 300GB

N series gateway overview Transform Legacy Storage N series unifies SAN and NAS as well as virtualizes SAN storage from multiple vendors into a single pool for file or block access to provide the benefits of Data ONTAP and the N series manageability software family.

Why Gateway vs. General Purpose Filer Server Clients & Servers A single Gateway supports Unix, Linux and Windows file protocols Potentially reducing the number of servers required for accessing SAN storage in mixed protocol environments Connecting small inexpensive servers to premium priced SAN storage is very costly. FC HBAs, FC switch ports costs could exceed the actual cost of server A single Gateway extends the reach of SAN storage to many servers attached to an IP network Unix Windows FC IP. N series Gateway FC Potentially reducing overall connection costs Allowing access to SAN storage at extended distances A Gateway provides functionality of N series technology to other vendor storage subsystems A Gateway provides increased protection investment in SAN storage by increasing SAN utilization & accessibility 44 IBM System Storage N series Overview Linux Tiered Tiered Heterogeneous Heterogeneous Storage Storage
