Access "Choosing the right VTL"
This article is part of the Vol. 5 No. 6 August 2006 issue of Five companies on their storage virtualization projects
VTLs are built around four architectures that address issues such as media portability and backup software compatibility differently. Virtual Tape Libraries (VTLs) are being deployed in ever-increasing numbers as the primary target for backups and the source for recoveries. But because VTLs are inserted before tape drives in the backup and recovery process, performance and management issues are cropping up that VTL vendors are just beginning to address. Before jumping on the VTL bandwagon, you need to answer the following questions: How well does the VTL scale to meet higher connectivity or capacity needs? What management features does a particular VTL offer? How well does it integrate with backup software? What impact do features like compression, data deduplication and encryption have on VTL performance and capacity? VTLs are built around four different architectures that, in various ways, address these questions. VTL storage appliance. The VTL is a single appliance that contains both the disk drives and the controllers that host the VTL software. Examples... Access >>>

Special Supplement: iSCSI: Low-cost alternative to FC
Based on the familiar TCP/IP networking protocol, iSCSI arrays are easy to implement and manage, and cheaper than Fibre Channel (FC)-based systems. They're also becoming a popular alternative to NAS and DAS for SMBs and remote office locations.
Special Supplement: Small office SANs
Leading vendors are offering entry-level Fibre Channel and iSCSI SANs at record low prices. And you can get a lot for your money.

Virtualization: Tales from the trenches
We profile five companies that have deployed, or are currently testing, storage virtualization and analyze their implementation experiences. The storage pros behind these efforts tell us how the products they chose are working in their production environments.
A step-by-step approach to data classification
The most common shortcoming of a data classification project is the perception that it can be completed through technical analysis at the storage layer without engaging business users. While discovering and analyzing storage is part of the process, good classification requires engaging business users or their IT representatives.
Choosing the right VTL
Disk is increasingly a key part of the backup process, and many companies are taking the virtual tape library (VTL) route to disk-based backup. But all VTLs aren't the same. Find out the key differences among VTL products, and how they might work in your shop.
Automate data recovery
Policy-based storage management can automate the data recovery process. But you need to know what types of policies various products support, where the policy manager resides and what it's capable of doing.
Data migration: Proceed with caution
This first of a three-part series on data migration products focuses on host-level data migration products. Data migration apps can automate, centralize and simplify data migrations while ensuring data integrity.

Getting started with database archiving
E-mail archiving gets a lot of the attention these days, but databases shouldn't be overlooked. Database administrators end up managing old and unchanging data within their production databases, so backups are constantly protecting data that hasn't changed.

More than 50% of the time electronic discovery requests aren't satisfied.
Storage Bin: In the last year, 91% of large corporations have been through an electronic discovery request. Thirty-three percent of these companies go through one or more requests per month, while 66% of midmarket companies have the same issue. And more than 50% of the time, the requests aren't satisfied.
How to count the cost of storage
by Stephen Foskett
The cost of each gigabyte of storage is declining rapidly in every segment of the market. Enterprise storage today costs what desktop storage did less than a decade ago. So why are overall costs increasing?
