The iSCSI SAN has been increasingly deployed by UK storage shops year on year since the technology first hit the market. It has carved out a niche as a lower-cost means of providing shared storage than Fibre Channel SANs. Many organisations have adopted iSCSI storage as they moved to shared storage from direct-attached disk, especially as a means of supporting server virtualisation projects. But what is iSCSI storage good for, and what are its performance limitations?
In this Special Report, you'll find out how iSCSI and Fibre Channel compare in terms of performance, use cases and cost; how to implement iSCSI SANs and overcome key deployment challenges; the straight dope on some key misconceptions about iSCSI; best practices for using iSCSI storage with virtualised servers; and how it compares with Fibre Channel as shared storage for VMware. Use this report as a resource for learning everything you need to know about iSCSI SAN storage.
An iSCSI SAN is well worth considering for many organisations in a post-recession, cash-constrained world, especially those who need to move from direct-attached storage and deploy a SAN without breaking the bank. But does an iSCSI SAN offer sufficient performance, and how does it compare with the incumbent storage king of the data centre, Fibre Channel? Find out in this UK focus on iSCSI storage.
In this podcast, Chris Evans of UK storage consultancy Brookend talks about the key steps in implementing an iSCSI SAN, the key challenges users can encounter during deployment and how to avoid them.
iSCSI storage has become an increasingly popular SAN protocol. But despite iSCSI proving to be a worthy alternative to Fibre Channel in enterprise data storage environments, there are still a lot of misconceptions surrounding the technology. In this podcast Greg Schulz, founder and senior analyst with the StorageIO Group, discusses some of the common misconceptions surrounding iSCSI. Learn how iSCSI functions with network-attached storage (NAS), if iSCSI disk drives actually exist, and whether iSCSI can be partitioned as RAID.
Virtual server environments need shared storage, and there's been considerable buzz about iSCSI SANs for use in such deployments. But, is iSCSI up to the task of providing storage for the heavy I/O and networking loads that virtualised environments bring, and what are the limits of iSCSI storage in its software and hardware incarnations in such use cases?
i SCSI and its sister IP protocol, NFS, have quickly become popular storage protocols for use in VMware environments. While there's ongoing debate about which protocol fits best with VMware, the decision comes down to what the implementer is most comfortable with and which protocol they can afford. In many cases, that choice is iSCSI, and this article looks at some best practices for leveraging iSCSI in VMware environments.
