Cover Story: Various BC solutions
Solutions for business continuance

Vendors are gearing up to address the requirement for business continuity and disaster recovery solutions in the enterprise. Here's a roundup of what's available. by Brian Pereira

As businesses prepare to implement BCP, IT managers are on the lookout for appropriate solutions. Different types of data require different levels of protection. CIOs will try to protect the most critical data/systems first. And so you have a variety of business continuity and disaster recovery solutions, ranging from tape backup to management and synchronization software for a completely duplicated hot site.

We at Network Magazine have neither tested these solutions nor verified vendor claims. The purpose of this article is to inform IT managers about the various solutions available.

Novell eDirectory 8.6 is architected with business continuity and disaster recovery in mind, providing for replication over multiple servers and sites to ensure that this critical data is available to power all Net services software to quickly restore the network. In addition, the live continuous backup in eDirectory 8.6 enables all data within the eDirectory to be backed up while the directory is in production without the need to shut down the server to backup data.

Network Appliance: To address business continuity, NetApp's strategy includes:

1. Hardware: All hardware is redundant, hot swappable and hot upgradeable. A NetApp customer can add terabytes of disks online, with no disruption/degradation.

2. Loss of a File: SnapShot keeps up to 31 copies of data online at 5 - 10 percent disk overhead and zero percent performance hit. So a lost file can be recovered instantaneously, instead of going to tape for painfully long restores.

3. Loss of a File system, virus corrupting a file system, database crashing, database corruption: SnapRestore from NetApp can take a Filesystem/database back to a consistent SnapShot in two minutes (for any size of data). This ensures recovery from corruption in the shortest time possible.

4. Two disks failing in a RAID group. NetApps SyncMirror implements mirroring of RAID protected volumes, thus ensuring availability for three or more simultaneous disk failures.

5. Loss of an entire site: SnapMirror from NetApp transfers changed blocks (not changes files/tracks) over a WAN link, thus ensuring one or many consistent copies of data at remote location.

RSA: RSA Security provides solutions that address the key security challenges of an organization in setting up reliable and scalable disaster recovery infrastructure. These cover two areas namely two-factor authentication (RSA SecurID) and Web access management.

Two-factor authentication technology, RSA SecurID becomes imperative in ensuring that organizations are able to undeniably identify users accessing the network resources (e.g. routers, active switches, etc), mission-critical servers for domain authentication (NT, 2000, Solaris, etc) and data storage components.

RSA Security's Cleartrust is a privilege management tool that allows organizations to manage Web based access to critical information resources.

Sun Microsystems: It has an array of products, services, and alliances for business continuity. These comprise of the SunPlex Environment, Dynamic System Domains, Remote Dual Copy, and Sun StorEdge L11000 Tape Library.

  • SunPlex Environment: Sun Cluster software, a key component of the SunPlex environment, is designed to deliver high-availability application services to the data center or enterprise.
  • Dynamic System Domains bring mainframe-style partitioning capabilities to the Unix world. These domains allow a single Sun Enterprise 10000 server to be logically divided into multiple or 'stand-alone' servers. Every Dynamic System Domain remains logically isolated from any other domain in the system.
  • Remote Dual Copy is an important capability for real-time remote mirroring on the StorEdge A7000 Server. When a company needs data with high availability and high integrity to be on-line, all the time, the Remote Dual Copy (RDC) feature on the A7000 storage server meets these requirements.
  • Sun StorEdge L11000 Tape Library is Sun's highest capacity, highest availability tape library designed to support the backup and recovery needs of data center customers running data-intensive applications in mission- critical environments. It offers approximately 11 terabytes of capacity, making it the ideal backup solution for massive file systems.
  • Sun Data Center Consolidation Program helps companies reduce information technology complexity and lower total cost of ownership. This program is designed to help customers reduce the complexity and cost of their IT infrastructure by physically consolidating their servers and logically consolidating applications.

Trend Micro: The enterprise security company has a global initiative for business continuity called the Enterprise Protection Strategy. Through this strategy it aims to shift the industry paradigm:

  • From point solutions to a lightweight infrastructure architecture (centralized management, services, products) that deploys and updates outbreak management strategies throughout the network.
  • From managing pattern files to proactively managing the outbreak lifecycle.
  • From reliance on costly human/system resources to organized and scalable intelligence management throughout all phases of an outbreak.
