IDC studied a group of enterprises that had deployed SAP applications on IBM Power Systems servers running Linux server operating environments and had been working with those systems for several years:
1)Annual benefits totaled $25,000 per 100 users For a large organization with 10,000 users, this would amount to more than $2 million in benefits.
2)The utilization rate for servers more than doubled, from 34% to 70% and many more
Traditionally, virtualized servers have relied on the hypervisor to fully manage data flow, providing powerful services and management capabilities, but also introducing overheads that dramatically impact network I/O performance. The new PCI standard, single-root I/O virtualization, or SR-IOV, has emerged to address these performance issues.
This solution brief explains how to cost-effectively improve network I/O performance on virtualized servers and comply with the new standard.
Citrix partnered with Solarflare to develop a unique unified approach to SR-IOV that delivers unprecedented cut through I/O performance while maintaining full hypervisor-based management.
As a result, virtualized servers can now benefit from accelerated network performance as well as hypervisor-based services and management capabilities.
Learn how to achieve higher I/O performance, scale to consolidate more workloads, and maintain efficient hypervisor-based services and management.
