Reasons to Hire a Professional to Fix A Broken Hard Drive

Happy technician working on tablet pc beside servers in data centerIt is definitely bad news if your hard drive broke because you were investigating why the disk was failing in the first place.

Although fixing your hard drive can be really costly, you will at least be able to ensure that the problem is provided with a sure-fire solution.

Transaction Processing Creates Real Benefits

tpcOld guard, new beat: TP monitors avert gridlock by policing client/server traffic

It’s an IT manager’s biggest nightmare. On a dark and stormy night, a WAN link suddenly crashed, taking down the national client/server reservation system for a company that wishes to remain anonymous. Harried travel agents kept pounding transactions into the system, expecting it to come up. When it did, the system was immediately slammed by a barrage of pent-up traffic. Designed to handle hundreds of transactions per second, the system choked on thousands and it crashed once again.

This company’s harrowing experience illustrates a dirty little secret about client/server applications. When they’re spun across the enterprise, many can’t handle the high-transaction traffic or unpredictability of com-plex, production-level environments. Increasingly, some companies like the one above are turning to a tried-and-true mainframe approach to keep their new client/server …

Client/Server Apps Still Make For Corporate Advantages

cscrappsForaging for corporate gold? If you haven’t paid heed to business rules, you’re burying your head in the sand. These rules need tending like any other company asset.

In their finished form, business rules can be a line of code such as “Value=Qty*Price*(1- LOOKUP Order Discount)” on a database server, credit-limit guidelines on a server in the sales department, or commission structures housed on the old PDP-11 at corporate headquarters.

Given the complexity of client/server environments, companies can no longer afford to have these rules scattered throughout an organization. One solution: a three-tier architecture that splits the rules apart from the application logic and hands developers more flexibility in managing these new resources.

Columbia’s SnapBack Set The Stage For Solid LAN Backups

lanbdThere are three main reasons that network administrators back up LAN-based data: to conserve disk space through migration, to aid users who mistakenly delete crucial files (invariably the CEO, according to backup vendors), and to prepare for disaster recovery.

The first two reasons dictate choosing a backup package that ensures highly reliable data tracking, with query tools that support multiple search methods for rapid file location and retrieval.

However, when attempting to prepare for recovery from such catastrophes as total server failure or a natural disaster, the real push for swift restoration comes from the dollars ticked off on the lost-productivity clock.

This is where the simplicity and strength of Columbia Data Products Inc.’s SnapBack can pay off in spades. Instead of conventional file-by-file backups, SnapBack creates an image backup of an entire disk drive.
