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.

Presentation Transcript
slide2
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.

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

slide4
1. Maintain the Option of Choice
  • Common method: assign I/O to a server by installing a card (typically via a PCI Express (PCIe) I/O slot)
    • Limits end-user I/O choice /application flexibility; increases overall app cost
  • An IOV system must present any I/O type to any server (physical or virtual)
    • Open, standards-based; flexibility controls quality, performance and operational costs
slide5
2. Be Ready to Scale
  • Depending on number of servers (i.e. high-density blade or flexible rack-mount), IOV systems and pools must scale
      • I/O performance: coupled to servers and closely managed bandwidth, latency and policy requirements of the application; or
      • Share I/O resource pools across many servers using certain level of subscription.
slide6
3. Make IOV an Extension of your Existing Infrastructure
  • IOV does not replace network access switches or change the configuration of network or SAN
    • IOV should accommodate direct server or network attachment modes:
    • Server-attached: ‘on-ramp’ to existing network and storage infrastructure
    • Network-attached: standards-based protocols provide I/O access over a common network and storage infrastructure

CEE

Switch

  • Datacenter Fabric
  • (CEE)

Ethernet

I/O Resource Pool

SAN I/O

SAS/SATA

Video/GPU

Flash SSD

Utility I/O

etc

slide7
4. Implement a New Data Center Mantra
  • MAKE, MONITOR, MANAGE and REPEAT
  • I/O must be actively managed by new rules, monitored for status and performance and provisioned on-demand.
  • IOV systems should also support prior management practices and processes.
