  storage solution landscape
• A better understanding of how iSCSI integrates
  into the Windows platform

iSCSI Defined What Is iSCSI?

• iSCSI internet Small Computer System Interface
• An interconnect protocol that
• Is designed for storage area networks (SANs)
• Supports the block-based storage needs of
  database applications
• Is TCP/IP based
• Establishes and manages connections between
  IP-based storage devices, hosts and clients
• Is based on familiar and ubiquitous open
  standards
• Provides advanced IP routing, management, and
  security tools

6
iSCSI Defined An Alternative to FC SAN?

• A non-Fibre Channel means of deploying storage
  networks
• Low intangible costs (management, training,
  deployment)
• No inherent distance limitations on the protocol
• Flexible topology
• Easy to use with multi-vendor storage devices
• Easy to scale to large number of devices

DAS Direct Attached Storage High TCO Inflexible
NAS Network Attached Storage File storage traffic

Industry Trends Factors Slowing SAN Adoption

• Actual SAN adoption far lower than respondents
  had
• predicted in 2002. Why?
• Perceived as too costly, even in large
  organizations
• SMBs do not have the staff or the expertise to
  support a SAN

Industry Trends iSCSI Impact on SAN Purchases

• Organizations are constrained by
• Limited budgets
• Hiring freezes or cutbacks
• Increased storage requirements
• iSCSI SANs capitalize on
• Existing LAN and WAN infrastructures
• Existing staff expertise
• iSCSI perceptions will drive new SAN purchases
• According to the IDC, most potential buyers
  believe
• It will be easy to learn iSCSI
• Same staff can be used for network and storage
• Allows buyers to use standard network equipment
  for storage network
• iSCSI products are likely to cost less than FC
  over time
• iSCSI products are likely to be less expensive to
  manage over time
• iSCSI products will have the same or better
  performance as FC

Industry Trends SAN Adoption - Growth Areas

• Users have pent-up demand for iSCSI/IP based
  storage
• Full range of price points and brands are
  required torealize potential

Among those involved in the purchase of SAN
solutions or employed at a company using/planning
to use SAN solutions (N 332) What types of SAN
technologies are currently in place at your
company and what technologies is your company
planning to use 12 months from now?

  iSCSI
• 2004 73
• In general, awareness is higher
• The larger the total installed storage capacity
• When there are more than 10 servers/10 IT staff
• Potential buyer interest is highest in large
  organizations
• Buyer group mean of 273 switch ports
• Non-buyer group mean of 67 (Source IDC Sept
  2003)
• Many smaller businesses deterred by high cost
  disk arrays(25K-100K)
• US market currently has an estimated 8 iSCSISAN
  installations
• Currently mid-market (30-300 installed servers)
  leads the installations (Source IDC, August
  2004)
