The design and shape of cordless power tools makes then fit into areas where corded power tools will not. In many cases, this leads to a sacrifice of turning strength from the motor. Dewalt power tools makes larger voltage cordless power tools to deliver more power for your job. Dewalt cordless power tools are the ones most often selected by professionals. Their dependability and ability to perform heavier work than most of the other lines of cordless tools is the reason for this. When doing repetitive work like hanging sheet rock, drill bits for driving the screws holding the sheet rock in place, tend to wear out and need replacement often. The quick-change heads of Dewalt power tools make this an easy task to accomplish with minimum slowing of the work being performed. Dewalt power tools offers a nice line of cordless screwdrivers and variable speed drills. The power ratings range from 7.2-volt motors up to 24-volt motors delivering the type of power you need. A variable speed drill is used to make a variety of different size holes from very tiny ones used to enable nails and screws to be driven without splitting the wood to large ones used for installing door knob assemblies. When using a variable speed drill, start your drilling slowly to allow the bit time enough to get firmly seated in the hole. This will lessen the chance of the bit jumping when higher speeds are applied which might cause you to drill something you did not want to have drilled. Dewalt power tools offer a full range of both corded and cordless tools. Their durability and easy ability to change accessories makes them highly desired for professionals. Dewalt power tools deliver in work conditions where other power tools fail. The only drawback I can see to this magnificent line of cordless tools is their weight. Having larger voltages to deliver more power means larger battery packs and larger motors as well. If you have to use one of these heavy cordless power tools all day, you will feel like you have done an intensive workout. Because this is a superior product, you can expect to pay a superior price for it as well. While you will see sales for the combo packs available in store ads, you may notice that these are the lighter weight tools. They will perform the work desired in most situation, but for the really heavy duty applications the heavy duty power tools will command a heavy duty price tag. iSCSI vs. FC for Meeting Mission Critical Requirements Efrat Levi 2662 IntroductionMission Critical Data is just what its name says: critical to the core functioning of an enterprise. Mission critical data must be available 24x7 and fully backed up for immediate recovery in the event of disaster. Enterprises are constantly seeking more reliable, more efficient, more convenient and more affordable ways of meeting these needs. SANRAD's V-Switch 3000 uses Iscsi technology to centrally consolidate, manage, backup and restore mission critical data at a fraction of the cost, in capital and human resources, of existing FC SAN technologies.Mission Critical Requirements and SANRAD's SolutionsStorage Area Networks (SANs) are used to manage mission critical data and, as they have developed, storage and network administrators have identified three main requirements on a SAN to manage this critical data: Benefits of iSCSI SAN over FC SAN When creating a SAN, enterprises find that the traditional answer is FC SAN. However, the investment required to implement an FC SAN is often beyond the means of a young enterprise. As a result, growing enterprises may find themselves delaying the inevitable upgrade to a SAN and, therefore, gambling with their mission critical data store. Business Case: V-Switch 3000 vs. FCTypical SAN topographies can be divided into 5 groups according to the number of servers accessing the SAN and the net storage capacity of the SAN. In a SANRAD V-Switch 3000 SAN, this would also require two V-Switch 3000s. Upstream of the V-Switch 3000s there are two multi-Gbit switches but no special host software or HBAs are required. Downstream of the V-Switch 3000s are the legacy SCSI or FC JBODs with a net mirrored capacity of 1.5TB.
ConclusionSANRAD iSCSI SAN provides all of the key SAN requirements needed to manage, backup and restore mission critical data with added benefits over FC SAN. SANRAD's V-Switch 3000 represents a single integrated hardware/software solution to SAN management, including storage pooling, virtualization, mirroring, striping and remote backup. The IP-based iSCSI SAN permits remote storage access and provides greater flexibility in the location of network and storage components within an enterprise and it does so at a fraction of the cost of an FC SAN. 2chttp://www.ideamarketers.com/./library/article.cfm?articleid=72075 | ||||||||||||||||||||
