© Novell Inc, Confidential & Proprietary iSCSI iSCSI is a new internet standard which defines how industry standard SCSI (Small Computer Systems Interface) storage protocols are run over industry standard TCP/IP. V1.0 was ratified on February 11, 2003 This was Internet Draft version 20 of the specification: “SCSI protocols are request/response application protocols with a common standardized architecture model and basic command set as well as standardized command sets for different device classes (disks, tapes, media-changers, etc.)” “iSCSI is a transport protocol for SCSI that works on top of TCP/IP. The iSCSI protocol aims to be fully compliant with the standardized SCSI architectural model.”

© Novell Inc, Confidential & Proprietary The Solution: An inexpensive SAN iSCSI on Gigabit Ethernet Hardware is a fraction of the cost of a full Fibre Channel SAN solution. Estimates are 4 to 10 times less expensive for the same amount of storage Not as performant as Fibre Channel Use existing servers as your shared storage. DAS servers converted into iSCSI Storage Arrays. No new hardware costs incurred.

© Novell Inc, Confidential & Proprietary Agenda Storage Trends – How to manage the growth? What is iSCSI? When to use iSCSI? Novell iSCSI Solutions Novell iSCSI disk server iSCSI and LDAP Question and answer

© Novell Inc, Confidential & Proprietary When to use iSCSI? iSCSI vs Fibre Channel is the wrong question There are no indications that iSCSI will replace Fibre Channel iSCSI will bring SANs to those who would not implement Fibre Channel iSCSI will supplement Fibre Channel for 2 nd and 3 rd tier data storage Bridged into Fibre channel Customers want to use Fibre Channel in the classic data center Already deployed Better Performance Better support from HW vendors (you get what you pay for)

© Novell Inc, Confidential & Proprietary When to use iSCSI? iSCSI may replace Fibre channel as data centers become more dense and iSCSI and ethernet speeds improve to beyond 1GB Blades with iSCSI Presently, customer interest and needs from iSCSI are as follows: Data migration DAS to SAN migration Site to site migration Distance replication Disaster recovery Geographic data caching Serverless backup Low cost Clusters
