Access "Using iSCSI storage with vSphere"
This article is part of the Vol. 9 Num. 5 July/August 2010 issue of Good match: iSCSI and vSphere
To realize the greatest benefits of a vSphere installation, you need networked storage. iSCSI is a good fit for vSphere; here's how to make it work. By Eric Siebert To tap into some of VMware vSphere's advanced features such as VMotion, fault tolerance, high availability and the VMware Distributed Resource Scheduler, you need to have shared storage for all of your hosts. vSphere's proprietary VMFS file system uses a special locking mechanism to allow multiple hosts to connect to the same shared storage volumes and the virtual machines (VMs) on them. Traditionally, this meant you had to implement an expensive Fibre Channel SAN infrastructure, but iSCSI and NFS network storage are now more affordable alternatives. Focusing on iSCSI, we'll describe how to set it up and configure it properly for vSphere hosts, as well as provide some tips and best practices for using iSCSI storage with vSphere. In addition, we've included the results of a performance benchmarking test for the iSCSI/vSphere pairing, with performance comparisons of the various configurations. ... Access >>>

Unified storage offers savings and efficiency
Unified, or multiprotocol, arrays put file and block storage in the same box. It's convenient and, according to our survey, an efficient way to manage storage.
Hospitals strive for centralized image archives

Continuous data protection; it's back!
by W. Curtis Preston
When CDP products first appeared a few years ago, the benefits were clear, but implementation and other issues quickly stifled interest. Now CDP is making a comeback, and it might just be the future of data backup.

Align data protection with business importance
There's a big difference between backup and business continuity. Any-point-in-time technologies can extend data protection so that application use is protected as well.
The new primary storage
A technology borrowed from backup may end up the biggest thing to happen to storage in a long time.
Cloud storage ecosystems mature
by Terri McClure
Vendors have emerged that provide a bridge to cloud storage services, as well as extended security, availability and portability to cloud storage service provider offerings.
IT still an awkward fit at most companies
by Tony Asaro
However you look at it -- top down or bottom up -- most IT operations are treated as expense centers, fiefdoms or afterthoughts, rather than critical parts of the business.
