August 2011-
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.<br><br>
This solution brief explains how to cost-effectively improve network I/O performance on virtualized servers and comply with the new standard.

December 2010-
Server virtualization offers tremendous benefits for enterprise IT organizations — server consolidation, hardware abstraction, and internal clouds deliver a high degree of operational efficiency. However, today, server virtualization is not used pervasively in the production enterprise datacenter. Some of the barriers preventing wide-spread adoption of existing proprietary virtualization solutions are performance, scalability, security, cost, and ecosystem challenges.
Red Hat Enterprise Virtualization for Servers is an end -to-end virtualization solution that is designed to overcome ...

Many businesses are considering migrating from proprietary technologies to those based on free, industry-wide standards. This will not only carve out IT costs, but also help scale your IT ecosystem and potentially improve performance.
To better understand the customer migration experience, the Harvard Research Group (HRG) interviewed IT professionals, hardware vendors, software vendors and the Red Hat customers who performed migrations from previous-generation platforms to Linux. HRG examined server, application, and workload migrations, ...
Linux Data Replication Methods for High Availability
[ Source: RapidScale Clusters ]
July 2010-
In Linux system administration, it is often critical to replicate data to another server for high availability. There are several possible methods, including simple asynchronous copies, developing change detection software, and using synchronous cluster file systems. These methods all have pros and cons. Equally important is the kind of data to be replicated. Large files, small files, and frequently changing files impose different requirements. These issues are discussed, and in conjunction with the different methods, ...
