Distributed Platforms Provide A Major Difference To Networks

nwsSingle-console network management gets in the way of using your staff economically. Distributed platforms are on the way, but make sure the one you pick covers all the bases.

NETWORK MANAGEMENT platforms sometimes remind you of a cheap suit. No matter where you get them, they’re too small here, too big there. They just never quite fit your network without a lot of expensive tailoring.

In business networking situation, 62% have their network management stations in the centralized mode, 26% use it in distributed mode. Six percent have no LAN management, according to a survey of 354 Fortune 1,000-equivalent organizations by Business Research Group.

And yet that “other,” meaning not centralized and not decentralized but a cross. between the two, seems to be a badly needed alternative. According to the same survey, 73% of organizations consider the ability to do remote network management absolutely critical. And, according to earlier surveys by BRG, many organizations are concerned about the high and continually increasing expense of network management staff


Details are still sketchy on the distributed architectures of the three big firms selling SNMP management platforms. To be fully functional, according to Mier, the products will have to meet these three criteria:

* They must provide management-station-to-management-station communications, and the vendors must specify the network protocol and the database structure for doing that.

* There must be a user-defined procedure for sharing information and responsibilities between management stations so that management data wouldn’t flood the network, nor would any station have insufficient data for its purposes.

* The distribution of data and access to the management database should be screened from unauthorized people, and there should be a way to ensure that management commands are issued only by authorized stations.

To what extent planned products meet these criteria is still not clear. For example, most of the vendors plan to allow users to encrypt management-to-management traffic, but won’t include it as an integral feature of their products. And some are not too certain whether the database structure they will use will be truly distributed or shared at a common central point. Most say they’ll allow users to pick one of the major database systems, such as Oracle or Sybase, but allowing that choice is not the same thing as setting up a structure.

Although the vendors’ actual plans are unclear, they all share the view that distributed SNMP will be essential in years ahead. As Janet Hyland of Forrester Research points out, the high invisible cost of managing LANs has not declined in recent years. Indeed, they can cost as much as $1,270 per node per year. “Companies are paying through the nose for on-site bodies to compensate for the lack of network and systems management products,” she says, adding that distributed management can help reduce that burden.

Not only are large, enterprise SNMP stations managing more and more nodes these days, says Gartner’s Garry, they’ll soon have an astonishingly higher processing burden when they begin to handle more systems management functions, such as PC software and asset management through the new Desktop Management Interface protocol.


What to do until distributed SNMP managers come along for the major platforms? Of course, there are proprietary management products, such as those of Boole & Babbage and Maxm Systems, that work as managers of managers. These can be used to link various SNMP managers. But, according to the BRG study, most corporations regard the proprietary manager of managers as unwieldy and expensive.

One group of network managers has already seen a glimpse of the distributed management future. Texas Instruments, for example, has been trying out Cabletron’s distributed management platform, which has been on the market since June, and reports initial satisfaction. But Cabletron’s Spectrum is a high-end product, and the company has been working on it for several years. There is evidence that the products of HP, IBM, and SunSoft are being rushed to market, and they may not work as would be to install a distributed node on a smaller LAN and see if all management information is shared and all promised capabilities delivered. Until that is certain, consultant Mier recommends using such products as Concord Communications’ Trakker, Network General’s Distributed Sniffer, or IBM RMONitor to handle remote diagnostics.

When the leading SNMP platform vendors offer true distributed management, it should help improve the scalability of management and the response times of networks. But do not dive in to distributed management. Closely question vendors and dip a foot first.

The Drawbacks and Uncertainties of Distributed SNMP Management

* Not all divisions may want to join

* Unfiltered polling and extraneous backup stations can increase network traffic

* Management traffic could loop

* Outsiders could penetrate the management structure

* Uncertain links to element management systems

* Unclear database architecture: Do management stations share a common database or distribute the management data?

* Potentially large investment in new tools for distributed management

Server Safety

The issue with these SNMP networks, unfortunately, is that they are only as good as individual nodes. A recent study conducted by Forrester showed that the most popular brands, namely Dell PowerEdge and HP ProLiant, were no longer supporting SNMP, noting that it is not as heavily used anymore. Both manufacturers had experienced high component stress using the protocol, which tended to cause issues with the multiple disk arrays present in these servers.

“SNMP ended up working well for some servers, and not for others,” says Ray Mullen, Dell Server Product Manager. The result has been that guides to recovering Dell PowerEdge server arrays like this tend to strongly suggest disabling the protocol before working on individual RAID servers.

How To Avoid Hard Drive Recovery Costs

Getting a hard drive failed is a disastrous situation for most of us especially if we have data on it which matters a lot to us. Getting your hard drive repaired and data recovered through a professional hard drive recovery service is not always that easily because you might not be willing to pay the high hard drive recovery cost to these professional services. However, luckily, there are a few instances where you can try to avoid hard drive recovery cost by taking some simple and safe steps. You may stand a good chance of recovering data on your own if the damage is not of serious nature.

Before you decide to hand over your drive to a professional data recovery company, make sure that the damage is not of the nature that it can’t be fixed on your own. Try checking the drive for bent pins, small scratches or similar physical problems. You also need to make sure that the problem doesn’t lie with the cables. Try replacing the power cable and data connection cable. Other diagnostic measures that you can take include connecting your hard drive to an external power source and trying to run it again, fitting your drive in another computer because it might be the motherboard at fault instead of the seemingly dead hard drive. If the problem arose due to the deletion of an important file or due to similar software related mishandling, you can try using free data recovery software. However, if these measures do not work, it is recommended that you take services of a professional instead of aggravating the problem in an attempt to avoid hard drive recovery costs.

Getting It Diagnosed

A dead hard drive cannot only be a great nuisance but most importantly, the biggest problem can be of data loss. However, in most cases, hard drive recovery can be done by following some simple steps. If the damage to your hard is not that of a serious nature, you may be able to recover it by taking a few simple measures. Let us find out what should be your foremost simple reaction in case of a hard drive damage to make sure that at least you do not aggravate the problem.

First of all, stop the usage of your external drive or computer immediately and power it off. If you are using a computer, you need to remove the hard drive from it so that you may examine it thoroughly and find out if it is damaged on specific sensitive spots. Check the external controller board carefully for damaged spots. Or else, there might be some broken tiny chips on your hard disk, preventing it from functioning normally. A careful examination is the first step towards hard drive recovery. If you are able to examine it carefully and identify the damaged areas, hard drive recovery would become much easier as half of the job would be already done.

What Causes Hard Drive Failure And Leads Us Towards A Hard Drive Recovery Service?

The major cause of data loss, post-generated issues those impact companies sales and become a reason for unintentional loss is hard drive failure. Although the problems created with HDD failure can be fixed to some extents or whole extent by hard drive recovery service but still we should know the causes those can lead to HDD Failure. In this way, we can prevent data loss as well as expenses on availing a hard drive recovery. Let’s give a glance on reasons of hard drive failure, mentioned as follows:

Physical Damage to the Computer: The physical damage involves a sudden pressure exerted on the machine or bumping accidentally with CPU. Moreover, sometimes accidentally, CPU may fall from computer table or laptop can be dropped unintentionally. Either the machine is turned off or turned on this does not matter. In fact, these actions have a clear impact on components of system especially on Hard Drive. These actions damage the magnetic platters of the HDD due to which data vanishes, known as Head Crash.

Heat: Non-perfect ventilation and inadequate room temperature and no rest given to the machine (over usage) can be fatal for the Hard Drive.

Virus or Corrupted Files: Due to several viruses (enter PC through USB & non-trusted internet sites) can damage the files. Moreover, some Anti-Virus software consider all of your files as virus and delete them marking them as a virus. These files can also be your system files.

Human Error: The human error is very common cause of hard drive failure. Turning off the computer without closing the software or files, deleting system files, closing files without saving them are considered as poor user habits and results in HDD destruction.

No doubt, focusing and following these causes can even cut off the expenditure using hard drive recovery service.

Armand Hammer: Suspect Icon

ahmTHE DEATH of Armand Hammer last month was marked by unrestrained encomia. In addition to a full-page obituary, the New York Times published an editorial that lauded the multi-millionaire’s keen eye for art,” his bold business sense,” his “restless intelligence and prodigious energy.” The editorial went on to praise his “tireless efforts to improve relations between the United States and the Soviet Union.” Somewhat bafflingly, the piece concluded with the tribute that Hammer was probably the only American who could have told Mr. Gorbachev what Lenin was really like.” Quite why Mr. Gorbachev would particularly want an American to tell him “what Lenin was really like” was left unclear.
