On-demand Connectivity for Utility Clusters
Today’s server I/O was designed for static environments where servers run just one application. But to create a truly flexible, on-demand pool of compute resources, server I/O must be quickly configurable, without disruption.
Xsigo virtual I/O replaces conventional cards and cables with dynamically configurable resources that let you adapt your infrastructure on the fly. Add network and storage I/O to any server at any time, or move I/O from one server to another, in seconds.
By accelerating I/O management, Xsigo virtual I/O delivers these benefits for utility computing:
1. Allows fast server repurposing.
Servers can be instantly configured with the needed storage and network connectivity. Time-of-day re-purposing now becomes feasible.

2. Enables any-to-any connectivity.
Any server can be configured with connectivity to any network or storage, without changing cards or cabling.
3. Delivers transparent application migration.
Accelerate application migration (or N+1 failover) by moving I/O among servers while retaining all I/O attributes -- including WWNs and MAC addresses. Migrate applications with no SAN configuration or network re-mapping needed.
4. Speeds application deployment by replicating I/O configurations.
Xsigo’s “server profiles” are user-defined profiles that specify I/O configurations for specific applications. Re-use server profiles to quickly replicate configurations.
5. Simplifies disaster recovery.
For faster, simpler DR, Xsigo lets you re-configure I/O at a failover site to match the primary site. No need to physically configure I/O.
With Xsigo, I/O management is accomplished in minutes, not hours or days. The result is greater server utilization, better application performance, and lower overall costs.
