Disaster recovery using virtual servers

July 29, 2009

Did you know, that in a virtual server environment, the physical servers can be used as disaster recovery servers for noncritical apps? Instead of sitting idle and collecting dust, they can be used for apps not required during a disaster.

Organizations looking to reduce recovery time, remote site costs, and improve ease of implementation, find that server virtualization combined with business continuity solutions, such as replication, is  a more cost-effective disaster recovery strategy. Research from Enterprise Strategy Group (ESG) finds that 26% of organizations are replicating virtual machine images to a remote disaster recovery site, and 39% plan to do so in the future. Check out this article from SearchStorage that describes the benefits of virtual machines for DR.

Here is a quote from Mark Bowker from ESG about virtualization for DR:

“Some people are deploying a single VM on a host for critical and resource-intense apps like Exchange to reap the DR benefits but ensure sufficient resources; the data protection advantages by far outweigh the slight virtualization overhead.”

Houston, we have no tape backups

July 21, 2009

Did man walk on the moon? Well if your are looking for original images of the first steps as proof, look again. It was recently discovered that NASA has lost the original footage of the Apollo 11 mission. Rumor has it that NASA was erasing old magnetic tapes and reused them to record satellite data (read the full story). Here is another case for tape backups (and actually keeping them). You would think important footage such as the first moonwalk would be kept under tight wraps– and at least backed up!

Use your IP network to centralize video surveillance

July 16, 2009

In recent years, video surveillance has shifted to the IP network. The change is not just for higher resolution images and longer retention, the growth of IP surveillance has resulted from a variety of benefits. One of the key benefits is consolidating hardware resources which increases performance, availability and utilization across the three parts of a surveillance network: cameras, video servers, and storage.

To learn more about centralizing surveillance resources on your network read this white paper, and watch this short video.

Of course there are more advantages of IP video surveillance, here’s a killer list provided by excITingIP.com:

Scalability: IP Surveillance system scales from a single camera to thousands of cameras (in the increments of single camera) by just increasing the cameras, memory and processing power of the back-end servers.

Reliability/Redundancy: As standard IP hardware is used, trouble shooting and availability of spare parts become easier for IP Surveillance. IP based data storage enables off-site storage and back up in multiple locations as standard hard disks are being used. And complete redundancy can be created at the network and individual component level (Servers etc) to make sure that there is no single point of failure.

Cost: IP Surveillance use the IP Network components like Catx cables and network switches. This network can also be shared with other applications. So, the cost of setting up and maintaining twisted pair IP network is lesser than the cost of setting up and maintaining analog co-axial cable networks, which might be useful only for surveillance.

Power for Cameras: Since Catx cables in IP Networks support Power Over Ethernet standard, both electrical power and data can be carried to the cameras in the same cable (Instead of requiring a separate power source/ adaptor/ power cabling etc).

Open Standards: As most of the IP systems are based on open standards, multiple vendor interoperability is possible with IP Surveillance.

Buying IP cameras online: Things to Consider

July 9, 2009

Seen a camera online for cheap? Thinking about buying it?  Well it seems harmless enough, but what if you run into installation, compatibility, or support issues?

I ran across a post on IPVideoMarket.Info that reveals an emerging trend of online camera purchases, and digs deep into the long-run issues (read the comments). Sure, if you need one camera for simple home surveillance then online buying may be logical. But what if you need 24 cameras for multi-site recording at high-resolution? Unless you change your own motor oil, do your own plumbing, cut your own hair, and  sew your own clothes, why not leave security configuration to the pros?

Online purchases tend to be cheaper and offer a wide selection, but how many people know if they are choosing the right camera for their deployment? Get in on the conversation, leave a comment.
