Extending the SAN for Cost Effective

Extending the SAN for Cost Effective Connectivity
and Disaster Recovery
LIVE Webcast June 21th, 2006
Todays data center managers are constantly
dealing with managing growth, and at the same
time new technology advancements. Last quarter
we talked about introducing iSCSI into the data
center and the benefit that introducing iSCSI can
have. How do we now connect low cost iSCSI
servers into datacenter fibre channel storage?
Data center designers also need to ensure
uptime and a seamless migration and failover from
one data center to another in the case of a
disaster. How can this be accomplished at a
reasonable cost without the traditional
complexity that comes with long distance
SANs? This web cast has been designed to answer
these questions and offer you some new ideas on
data center connectivity.

iSCSI Defined

• Internet Small Computer Systems Interface
• Provides access to storage over standard TCP/IP
  networks
• Maps SCSI to TCP/IP Protocol
• Similar to mapping SCSI over Fibre Channel
  Protocol
• Is a networking application like NFS, FTP,
  Telnet, etc

iSCSI Dynamics

• iSCSI is NOT FREE
• Requires dedicated network for deployment
• iSCSI HBA or additional CPU processing required
  for acceptable storage performance
• Can use existing Ethernet infrastructure
• Switches, Routers, VPN
• iSCSI is secure
• CHAP, VLANs, VPN, isolated network
• Interoperability NOT Guaranteed
• SCSI Initiator/Target qualification testing
  required
• SAN application and management software still
  required
• Similar to FC, SCSI over a network

SW Performance

• Cost effective
• TCP/IP Processing is CPU Resource Intensive
• 1Hz CPU per 1bps
• 1GHz CPU for a 1Gb Ethernet link

Fibre Channel and iSCSI Will Coexist

• Fibre Channel will . . .
• Maintain large enterprise dominance
• Currently working toward medium sizes business
• Declining prices
• Interoperability
• Easy to use mgmt tools

• iSCSI will . . .
• Expand SAN Connectivity
• Connect remote SANs
• Deliver SAN to enterprises with DAS today that do
  not want to invest into a new networking
  technology

Emergence of Intelligent Fabrics Traditionally,
storage related solutions have been restricted to
two architectural layers within your datacenters
host based and/or array based. Deployments
within those areas can provide advantages and
introduce challenges to IT organizations. There
is an appreciable movement within the storage
industry to start delivering solutions from
next generation SANs called intelligent
fabrics. Are you wondering how your IT
organization can take full advantage of these
emerging solutions?
