Access "Cisco's switch-based backup"

Published: 19 Oct 2012

Cisco's switch-based backup Cisco Systems inc. recently announced its Fibre Channel (FC) MDS 9000 Storage Services Module (SSM) and SAN-OS 2.1 software--which includes support for Xcopy, or Extended Copy--to enable Network Accelerated Serverless Backup (NASB). With serverless backup, the server is removed from the backup process so it doesn't become a performance and reliability bottleneck. Xcopy has been around for quite a while and is part of the SCSI command set, intended to enable copying data from one storage device to another without passing the data through a server. The notion of serverless backup is attractive because it offers faster backup speeds, lower server loads and less LAN traffic. Still, Xcopy hasn't been widely embraced by users. Users found that without backup software support, serverless backup had many problems that Xcopy didn't address (and still doesn't). What Cisco has done that's different from the Xcopy support built into other storage products is to make deals with backup software vendors to support their hardware, so the backup ... Access >>>

What's Inside

    • Use mainframes for backups

      You can put that big iron sitting in your data center to better use by using it to back up open-systems data, too. The net effect is a streamlined backup and disaster recovery operation.

    • 10 basic steps for better backup

      The most evident common denominator in well-functioning backup infrastructures is effective process and control. This checklist highlights 10 areas you should focus on to build a better backup practice.

    • Sizing up VTLs

      Virtual tape libraries present disk as tape, so backup apps can perform backups as usual, regardless of the physical backup infrastructure. Learn about hardware and software VTLs, the benefits of each and how they might fit into your backup operation.

    • Used tape sales on the rise by Alex Barrett

      Pre-used tapes are becoming a popular and inexpensive trend among IT professionals. Become familiar with the possible risks of using used tape in your environment.

    • Data migration: Preparation equals success

      Moving data from one array to another is becoming more commonplace for reasons such as implementing new or upgraded systems, tiering storage or archiving older data. Data migration is a complex and painful process, but these steps can help ease the pain.

    • First SAS products arrive by Alan Radding

      With a wave of new SAS products about to be released, some storage vendors are ratcheting up campaigns that promote SAS as the inevitable next step in the evolution of SCSI.

    • Blades shed disks, boot from SAN by Alex Barrett

      Users resolve boot issues with diskless blades.

    • How disk has changed backup

      Inexpensive disk has spawned a variety of disk-based backup alternatives. But with more choices comes greater complexity compared to the days when you simply had to choose a backup application and tape library. Backup guru W. Curtis Preston explains the advantages of using disk for backup, including virtual tape libraries and disk-as-disk backup targets, and discusses the pros and cons of alternative disk-based backup methods.
