The advantages of architecting an open iscsi SAN

Storage as it should be The advantages of architecting an open iscsi SAN Pete Caviness Lefthand Networks, 5500 Flatiron Parkway, Boulder CO 80301, Ph: +1-303-217-9043, FAX: +1-303-217-9020 e-mail: pete.caviness@lefthandnetworks.com Presented at the THIC Meeting at the National Center for Atmospheric Research, 1850 Table Mesa Drive, Boulder CO 80305-5602 July 18-19, 2006

LeftHand Networks Storage Software Company SAN/iQ - Full featured iscsi SAN Proven Market Leader Pioneered IP SAN storage in 2001 Over 1500 loyal customers Over 4000 SAN/iQ licenses in production Next generation SAN Solves the issues of legacy SANs Eliminates any single point of failure Scales without increasing complexity Leverages industry-standard hardware Three patents issued, others pending 7/26/2006 2

The Value of LeftHand iscsi SAN Architecture Central Management Console Corporate Network iscsi Initiators Mail Server Database Server File Server Storage Subnet (Gb Ethernet) iscsi SAN Modules 7/26/2006 3

Legacy SAN Architecture User data is tied to controllers behind backplane. Performance slows as you scale disks 7/26/2006 4

SAN/iQ Operating System Feature Set SAN/iQ Cluster Distributed Virtualization SAN/iQ Advanced Provisioning SAN/iQ Network RAID SAN/iQ Snap SAN/iQ Remote Copy 7/26/2006 9

SAN/IQ Clustering Ability to cluster multiple NSMs into a single pool of capacity. Clustering combines Storage capacity Processing power Multiple GigE ports Caching No limit on NSM s per cluster No limit on number of Clusters Results Unlimited storage scalability Increased performance with each NSM added 7/26/2006 10

Dynamic Cluster Expansion Adding Storage to a Cluster Adding storage to the cluster is as simple as adding any other Ethernet device. The intelligence within SAN/iQ automates the process of adding capacity with out downtime. 7/26/2006 11

Distributed Virtualization Volumes (LUN s) striped across all NSMs within a cluster Result: Volumes are evenly distributed Over all Spindles Over all Processors Over all Cache Over all Network Connections Provides redundancy and performance 7/26/2006 12

Dynamic Volume Expansion SQL Dynamic Volume Expansion No Server Downtime Users stay online If done Manually, requires File system expansion (Diskpart for example) 7/26/2006 13
