• Any storage network environment
  • Block and file services
  • FC and GbE infrastructure
  • Multiple servers(Unix, Linux, Windows)
• Consolidation of:
  • Storage (RAID, NAS, SAN-in-a-box, Tapes, and Optical).
  • Any service (File system, raw device, etc.)
  • Available bandwidth and capacity resources
• Network element (not storage itself)
• Handles all data and metadata that passes between the host servers and storage, allowing in-band security monitoring and policy administration.
• Hardware Modularity: Performance scales from department to enterprise
• Software Modularity: Customers pay for only needed features

Off the shelf components

• Commercial thin servers for controllers (Cloverleaf Controllers "CC") and management console (Cloverleaf Management Station "CMS").
• FC switches (Brocade, McData and Qlogic)
• GbE switches from the leading vendors
• Dual-port FC adapters (Qlogic, Emulex)

Scalable, fault tolerant design

• Cluster up to 12 Cloverleaf Controllers (CCs)

Open software environment

• Unix

Patch Panel

• Connect any external devices (servers/hosts, storage or external switches) to internal iSN FC/GbE fabric
• Automatic discovery

Multiple interfaces

• Interface to other customer devices (storages and switches) for discovery, configuration and alerts
• Interface to Enterprise Management Systems for SNMP alerts and reports
• Secure interface for remote GUI and CLI for iSN Administrators and Users

Core architectural features

• Scalable cluster of controllers connected via internal FC backbone with light protocol (System Area Network approach)
• Massive multi-threaded implementation supports up to 10,000 simultaneous I/O requests
• Advanced caching with variable cache page sizes providing higher density of pages into cache memory drastically improving the performance of storage arrays behind iSN.
• Snapshots metadata kept in DRAM, eliminating performance degradation as the number of snapshots increases
