Genesis of VZ & Grid Computing
CFO vs. CIO - Shocking Observations • IT Infrastructure Investments yet to achieve TCO/ROI Financial Objectives
• Expected Boost in Corporate Productivity not Visible
• Post 2000 Dictum: Do More with Less
Reason – IT Spiral • Web Growth > New Apps Mushroom > Lo Cost Win Servers Sprawl (Tier-1)
• Business Growth > Need More Computing Power > App/DB Servers (Tier-2,3)
• More Servers > Storage > DC Facilities > IT Support > IT Staff
• More Low Cost Servers > 5% Utilization >Scale Out Infrast. (Racks & Blades)
• IT Costs == Business Growth

Storage VZ Must Have Features • Scale Non-Disruptively in Capacity
• Snapshot Point-In-Time across Stg.devices
• Remote Replication across Heterogeneous Stg. Devices
• Policy Based Non-Disruptive Data Migration between
Heterogeneous Stg Systems & Between Stg Tiers
• Centralized Mgmt of all Stg.VZ under Single Image
• Support Tiered Storage
• Volume Management for Multivendor Stg. Systems
• Common Set of Tools: Provisioning, Mgmt & Replication
