Performance concerns surrounding iSCSI storage-area networks (iSCSI SANs) have caused the storage networking protocol to take a back seat to Fibre Channel SANs (FC SANs). However, the performance of iSCSI in virtual environments, not to mention cost advantages and ease of management, is helping to increase market share of iSCSI SANs.
SearchStorage.co.UK has compiled some recent information on iSCSI SANs for a closer look at this sector of the storage networking market. We'll start by examining why iSCSI SANs are finally proving to be a viable alternative to FC SANs in mainstream data storage environments. Then we'll take a look at some best practices for using iSCSI in VMware environments and dispel some of the common misconceptions that surround RAID and iSCSI SANs.
SAN finally proves worthy alternative to Fibre Channel SAN for the mainstream
Fueled by lower costs and simplified management, iSCSI SAN adoption grew in 2009 while the rest of the storage networking market decreased. While performance concerns have long since deterred FC users from considering iSCSI, recent vendor backing and proven performance improvements with server virtualisation have put iSCSI SANs in the forefront. Learn more about the benefits of iSCSI SANs and what effect 10 Gigabit Ethernet (10 GbE) and Fibre Channel over Ethernet (FCoE) will have on iSCSI SAN adoption.
in VMware environments: Best practices
iSCSI is quickly becoming the most popular storage protocol for use in VMware environments. This tip examines issues surrounding iSCSI in VMware environments, including why you should treat iSCSI as a storage network, why you should use only software initiators for iSCSi and why VMware vSphere 4 is a perfect fit for the technology.
storage: How to leverage RAID and ensure server uptime
A community college is looking to upgrade its IT infrastructure by getting rid of standalone servers and pushing toward virtualisation with Microsoft Hyper-V. While the plan is to cluster two servers running Windows Server 2008 R2 to iSCSI, the school's technician has a few questions surrounding RAID and server uptime. In this Ask the Expert, Greg Schulz of the StorageIO Group explores this process by discussing how RAID can be used with iSCSI storage and how iSCSI storage systems can be configured for high availability to eliminate single points of failure.
