This post will focus on Information Availability, the first of the four-part series this week.
|Here's another short 2-minute video, on Information Availability|
I am not in marketing department anymore, so have no idea how much IBM spentto get these videos made, but hate for the money to go wasted. I suspect theonly way they will get viewed is if I include them in my blog. I hope youlike them.
As with many IT terms, "availability" might conjure up different meanings for different people.
Some can focus on the pure mechanics of delivering information. An information infrastructure involves all of thesoftware, servers, networks and storage to bring information to the application or end user, so all of the chainsin the link must be highly available: software should not crash, servers should have "five nines" (99.999%) uptime, networks should be redundant, and storage should handle the I/O request with sufficient performance. For tape libraries, the tape cartridge must be available, robotics are needed to fetch the tape, and a drive must be available toread the cartridge. All of these factors represent the continuous operations and high availability features of business continuity.
In addition to the IT equipment, you need to make sure your facilities that support that equipment, such aspower and cooling, are also available.Independent IT analyst Mark Peters from Enterprise Strategy Group (ESG) summarizes his shock about the findings in a recent [survey commissioned by Emerson Network Power]on his post [Backing Up Your Back Up]. Here is an excerpt:
"The net take-away is that the majority of SMBs in the US do not have back-up power systems. As regional power supplies get more stretched in many areas, the possibility of power outages increases and obviously many SMBs would be vulnerable. Indeed, while the small business decision makers questioned for the survey ranked such power outages ahead of other threats (fires, government regulation, weather, theft and employee turnover) only 39% had a back-up power system. Yeah, you could say, but anything actually going wrong is unlikely; but apparently not, as 79% of those surveyed had experienced at least one power outage during 2007. Yeah, you might say, but maybe the effects were minor; again, apparently not, since 42% of those who'd had outages had to actually close their businesses during the longest outages. The DoE says power outages cost $80 billion a year and businesses bear 98% of those costs."
Others might be more concerned about outages resulting from planned and unplanned downtime. Storage virtualizationcan help reduce planned downtime, by allowing data to be migrated from one storage device to another withoutdisrupting the application's ability to read and write data. The latest "Virtual Disk Mirroring" (VDM) feature of the IBM System Storage SAN Volume Controller takes it one stepfurther, providing high-availability even for entry-level and midrange disk systems managed by the SVC.For unplanned downtime, IBM offers a complete range of support, from highly available clusters, two-site and three-site disaster recovery support, and application-aware data protection through IBM Tivoli Storage Manager.
Many outages are caused by human error, and in many cases it is the human factor that prevent quick resolution.Storage admins are unable to isolate the failing component, identify the configuration or provide the appropriateproblem determination data to the technical team ready to offer support and assistance. For this, IBM TotalStorageProductivity Center software, and its hardware-version the IBM System Storage Productivity Center, can helpreduce outage time and increase information availability. It can also provide automation to predict or provideearly warning of impending conditions that could get worse if not taken care of.
But perhaps yet another take on information availability is the ability to find and communicate the right informnationto the right people at the right time. Recently, Google announced a historic milestone, their search engine nowindexes over [One trillion Web pages]!Google and other search engines have changed the level of expectations for finding information. People ask whythey can find information on the internet so quickly, yet it takes weeks for companies to respond to a judge foran e-discovery request.
Lastly, the team at IBM's[Eightbar blog] pointedme to Mozilla Lab's Ubiquity project for their popular FireFox browser. This project aims to help people communicate the information in a more natural way, rather than unfriently URL links on an email. It is still beta, of course, but helps show what "information availability" might be possible in the near future.Here is a 7-minute demonstration:
For those who only read the first and last paragraphs of each post, here is my recap:Information Availability includes Business Continuity and Data Protection to facilitatequick recovery, storage virtualization to maximize performance and minimize planned downtime, infrastructure management and automation to reduce human error, and the ability to find and communicate information to others.
