Scale-out storage options boost capacity, I/O performance

Scale-out storage and scale-out network-attached storage (NAS) are gaining popularity in today’s storage industry. This tutorial takes a closer look at the new angles on scale-out storage. See why technologies like cloud gateways, scale-out NAS and object storage are replacing file storage. Read our case study about one company’s experiences with scale-out NAS. And listen to our podcast on scale-out NAS with Enterprise Strategy Group senior analyst Terri McClure.

Storage performance monitoring for virtual servers takes app approach

Like other areas of storage-area network (SAN) management, virtual server proliferation has made the job tougher for storage performance monitoring. Traditional tools that help you track I/O resources and alert you when performance thresholds are challenged may not be able to distinguish between a virtual machine (VM) and a physical host, leading to inaccurate data. However, the latest storage performance monitoring products have been adapted to virtual environments, and some are even specifically built for hypervisor technologies.

New wave of automated tiering software eases migration, adds control

In this tutorial on automated tiering, we outline the sub-LUN offerings the major storage vendors are promoting alongside their SSD options. We also explore five questions users need to consider as they evaluate sub-LUN tiering options. Finally, we spotlight the case study of an early adopter, Princeton Radiology Associates P.A., and its use of Compellent Technologies Inc.'s Data Progression auto-tiering software to illustrate some of the reasons why policy-based control and monitoring tools can be so important.

SSD storage decisions: Form factors, workloads, adoption rates

We lay out the four basic SSD storage form factors to choose from -- in disk arrays, as cache, in appliances or in servers -- illustrated with case studies of IT organizations that have implemented the products. You'll also find a podcast interview with SSD expert Dennis Martin that offers advice on how to choose between the different implementations, as well as how to determine which workloads to put on solid-state storage. Finally, find out if IT organizations are adopting SSD technology.

Data storage optimization techniques for primary storage gain foothold

We examine the companies positioning themselves in the primary storage deduplication and compression space to find out where the technologies are headed. We also speak with three users of NetApp data deduplication to learn how they've cut space requirements for their VMware environments. Finally, Tony Asaro, a senior analyst and founder of The INI Group, explains the challenges, benefits and use cases for data reduction in primary storage systems.

FCoE tutorial: Fibre Channel over Ethernet management challenges

This FCoE tutorial explores how three early Fibre Channel over Ethernet adopters confronted the management challenges associated with the deployment of the technology. We also describe the five best practices IT organizations should follow if they're serious about the convergence of LAN and SAN.
