Aprius solutions maximize application performance and minimize infrastructure costs in a data center by addressing network and storage I/O bottlenecks. The company offers a simple approach to provisioning and managing I/O resources by applying the principles of virtualization to server I/O including disk and flash storage, network and SAN interfaces.

1. The 4 Fundamentals of I/O Virtualization (IOV) A

2. 2 Server virtualization has led to the creation of other virtual resource types, including: | CPU | Memory | Storage | I/O | Network | I/O Virtualization (IOV) The logical abstraction of server I/O (including network and SAN connections, direct-attached storage, coprocessor offload, video graphics, etc.) into many virtual resources, allowing for the balanced matching of I/O to physical and virtual servers. 27-Apr-10

3. 3 4 Fundamentals of IOV Maintain the Option of Choice Be Ready to Scale Make IOV an Extension of your Existing Infrastructure Implement a New Data Center Mantra 27-Apr-10

5. Limits end-user I/O choice /application flexibility; increases overall app cost

6. An IOV system must present any I/O type to any server (physical or virtual)

7. Open, standards-based; flexibility controls quality, performance and operational costs27-Apr-10

9. I/O performance: coupled to servers and closely managed bandwidth, latency and policy requirements of the application; or

10. Share I/O resource pools across many servers using certain level of subscription.27-Apr-10

12. IOV should accommodate direct server or network attachment modes:

13. Server-attached: ‘on-ramp’ to existing network and storage infrastructure

14. Network-attached: standards-based protocols provide I/O access over a common network and storage infrastructureCEE Switch Datacenter Fabric (CEE) Ethernet I/O Resource Pool SAN I/O SAS/SATA Video/GPU Flash SSD Utility I/O etc 27-Apr-10

16. IOV systems should also support prior management practices and processes.27-Apr-10
