The leading vendors in the data warehousing market are running scared of new entrants to the market that are offering data warehouse appliances (i.e. pre-integrated hardware, software, storage combinations) that can offer greatly superior performance at a significantly lower price.  In this white paper we will dispel the 'fog of war' that currently pervades the data warehousing landscape, dismissing those question marks that are irrelevant and gratuitous, but highlighting any genuine issues that need to be addressed.

By BRIAN BERGSTEIN BOSTON - A new study that estimates how much digital information is zipping around (hint: a lot) finds that for the first time, there's not enough storage space to hold it all. Good thing we delete some stuff.

Adam Bosworth complains  about the current lack of quality and scalable databases in our industry.  "About five years ago I started to notice an odd thing. The products that the database vendors were building had less and less to do with what the customers wanted."  "It is this. Users of databases tend to ask for three very simple things:"  "1) Dynamic schema so that as the business model/description of goods or    services changes and evolves, this evolution can be handled seamlessly in a    system running 24 by 7, 365 days a year ..."  "2) Dynamic partitioning of data across large dynamic numbers of machines. A    lot people people track a lot of data these days. ..."  "3) Modern indexing. ...

(Source: Hewlett Packard) A typically complex, distributed, and heterogeneous IT environment is very difficult and expensive to manage, and a number of disadvantages to this model have become apparent. These include escalating operational costs, inflexible infrastructure, and erratic data security and integrity. Consequently, Butler Group believes that the proliferation of system silos found within the majority of enterprises today is not sustainable in the long term. Read this white paper to learn the significant benefits to data center consolidation and the adoption of a corresponding centralized management approach.

(InfoWorld) - Quantum introduced a disk storage appliance Monday that could both appeal to enterprise customers and improve its partnerships with other storage vendors. Quantum's DXi7500 is an integrated data deduplication, disk backup, and tape archiving device, also called a VTL (virtual tape library), that is a complement to the smaller DXi3500 and DXi5500 modelsÂ Quantum introduced in December 2006. The DXi7500 offers up to 240TB of disk storage capacity, versus 4.2TB and 11TB for the 3500 and 5500, respectively. A terabyte is 1,000 gigabytes of data. The new model also has a healthy appetite for data, deduplicating and saving it to disk at the rate of 8TB per hour. The DXi7500 would serve an enterprise by taking data already deduplicated by the smaller DX appliances at remote offices of a company and deduplicating it further, said Mike Sparkes, product manager for disk systems at Quantum. Deduplication is the software-based process of searching through data and eliminating multiple copies of files so that less data needs to be saved to disk storage. The Quantum system also creates a backup tape copy of that data, which is stored for archiving purposes. The system eliminates the need for tape backup at remote locations, which can be difficult for limited staffs there to manage. "Suddenly, you get to retain two or three months of backup data instead of two or three days," said Sparkes. "Instead of just being a buffer to tape, which VTLs have usually been, it becomes more of a permanent repository of backup data." The DXi7500 also gives enterprise storage managers the option of using either the in-line or post-process approach to saving to disk. With the in-line approach, data is transferred from a production server to the disk storage appliance for deduplication, but that is a time-consuming process that ties up the server, preventing it from doing more computing. The post-process approach moves data off the server quickly so the server can get back to work, but requires additional capacity in the storage appliance to hold all that data while it deduplicates it. Giving storage administrators a choice is welcome, said Robert Amatruda, research manager at IDC. "What they are doing is to provide some flexibility for the customers." VTLÂ technology is a nascent market, Amatruda said. IDC forecasts market revenue to grow to $4.1 billion by 2011 and for the amount of data stored in VTL systems to increase at a compound annual growth rate of 47.4 percent over the same period. Quantum can leverage the DXi7500 to strengthen existing ties with OEMs, such as Hewlett-Packard, Sun, and others, said Greg Schulz, founder of Storage I/O Group, an industry research and consulting firm. "Quantum sells a turnkey solution, which means for an OEM that they can just put their logo on it andÂ rebadge it, and people will buy it knowing it's a Quantum-based product," said Schulz.

If the load of application relies on incoming events, you may eventually face the happy curse of popularity: too much work to do with your available resources. If you set a limit on how many events you can process within a time period, you can avoid the flood. Vladi Belperchinov-Shabanski explains the algorithm and demonstrates working code.

Backup volumes in many organizations have grown so large that they are causing business disruption by tying up systems, storage, and network capacity and hogging valuable IT resources, according to a recent survey commissioned by storage management software vendor BridgeHead Software.More than half (59 percent) of IT executives said that the volume of data they are forced to backup is disrupting business operations or will do so eventually, according to a survey of 472 IT executives in the U.K. and North America. And the problem is not going away, with 93 percent saying that their routine backup volumes are continuing to increase.The problem is consuming IT resources for long periods with 37 percent admitting that daily backups of primary data now take them more than nine hours, while 19 percent said it took them more than 12 hours.More than two-thirds (84 percent) of those polled felt they could benefit by reducing the volume of data they routinely back up. Among the chief advantages highlighted were:* Less IT time devoted to backup and other business continuity processes (69 percent) * A reduction in the impact of backup and replication on network utilization and capacity (60 percent) * A reduction in disk resources devoted to data snapshotting, replication, and mirroring (58 percent) * Reduced disruption to the live application environment (45 percent)One of the most effective ways of reducing the pressure on backups is to take information that is static or seldom accessed and archive it off primary storage systems according to BridgeHead Software CEO Tony Cotterill."Sixty-one percent of organizations in our survey admit that between 30 to 50 percent of data on their primary disk is unlikely to be accessed ever again, yet they are squandering time and resources on backing up and replicating this big chunk of static data. It's a very poor use of resources," said Cotterill.BridgeHead said its research reveals that many organizations are starting to use archiving for specific types of data, such as e-mails, motivated by compliance and disaster recovery. According to the company, a lot of archiving activity is currently championed by finance and other business departments outside of IT's control.But to have a major impact on backup volumes, BridgeHead reckoned that there needs to be an IT-driven move away from point solutions or isolated archive appliances towards taking an organization-wide approach to archiving, allowing IT to retrieve control by archiving all data types across the organization from a single point."If you can take an organization-wide approach to archiving, then the volume of data you're taking off the primary store will start to reach a critical mass that will help call a halt to increasing backup volumes," said Cotterill.The survey was part of BridgeHead Software's Annual Information Lifecycle Management Audit, conducted by eMedia on behalf of BridgeHead Software during August 2007. eMedia surveyed 324 senior level executives, IT managers, system and network administrators and engineers from North America and 148 from the U.K.Techworld is an InfoWorld affiliate
