It Consultants Don’t Skimp On Hardware With Power Users

i5

As IT consultants, whatever you do, don’t let your clients skimp on PC purchases for power users who run high-end software.

While many of your small business clients employees depend mainly on software with modest hardware requirements, such as basic word processing, spreadsheet, e-mail and Web browsing software, there are certainly exceptions. Make sure you know who your clients power users are.

Power Users Need Cutting Edge Technology

If you have clients that depend on an advanced software application, such as graphic design, computer assisted design (CAD) or financial modeling, as IT consultants, you may want to advise your clients to implicitly “eat” that sky-high first years depreciation on the purchase of the latest and greatest PC hardware.

With processor and memory-intensive software applications, the employee productivity your clients will gain with leading-edge PC hardware likely will offset any major depreciation cost concerns.

Keep In Mind The Users’ Salary

Consider the salary required to attract and retain highly technical professionals who run advanced software applications. (As IT consultants, this high-salary-requirement-reality should come as no surprise.)

For example, if a clients of yours has a veteran graphic design artist or engineer on payroll at a $60,000 base salary, an extra $1,000 a year on PC-related expenses for this technical wizard easily could drive a productivity gain that makes the incremental expense seem trivial.

Get To Know Your Users

The moral of story: get to know your clients power users and their specific software applications needs. Just as important, clients power users are a kind of influencer that you need to be very aware of. Your clients power users are often very powerful votes when it comes to making decisions about hiring (and firing) IT consultants.

IT Consultants Should Consider “Hand Me Downs”

In many small businesses, the premium performance PC purchased for the power user gets replaced every year or two, and is passed down to an end user with less demanding software requirements. This is one way to extend the life of an expensive, high-end PC, while minimizing the out-of-pocket and related support expenses of bringing new PC hardware into your company.

Make sure your computer support, asset management and proactive maintenance plans all take this hand-me-down phenomenon into account.

The POS till includes inventory control, deducting items from stock as they are sold. The inventory count would be totally messed up if items were sold without going through the software inventory deduction procedures.

The POS hardware can be loaded with a range of retailer POS software solutions. These software programs allow stock to be deducted by items purchased, vastly improving stock control. Improved stock control means lower stock costs, less space required and improved profits.

Buying patterns can be analyzed simply and Customer Loyalty programs implemented if the right POS software is installed. Ordering can be automated and management much better informed regarding the performance of particular lines or departments.

Customer Self-Service POS hardware is more complicated still, so goes wrong more often. These machines include extra scales, so that individual items can be weighed to check the customer has not placed extra items on the belts without scanning them. Customers need to be educated in the use of the self-service tills, meaning that staff have to be available to assist customers with problems, or who are not used to the system.

Self-service POS hardware also includes cash handling equipment. The cash handlers need to be able to detect forged banknotes and to be able to dispense notes as well as loose change. The cash dispenser resembles an ATM and needs to be filled daily, with checks made that the correct loading procedure has been followed.

Hardware Virtualization Support In Modern Cpus

t13

To avoid the issues surrounding the non-trappable privileged instructions, CPU manufacturers have added virtualization capabilities to modern CPUs. These CPUs still need to behave exactly like their older counterparts, to ensure backward-compatibility with existing applications, so the behavior of the non-trappable privileged instructions is identical on these newer units. However, a new set of instructions, which were not previously available, provides for a special virtual machine mode of operation. This mode provides extra levels of I/O and memory protection, and allows the special instructions to be detected and handled externally by the CPU in conjunction with a suitably written hyper visor VMM.

The first revision of this instruction set provided basic support for virtualizing the non-trappable privileged instructions, and the supporting instructions required to interface the hardware support to VMMs written to make use of it.

CPUs with first generation hardware virtualization support are not capable of nesting VMMs in a way that allows the nested VMM to also take advantage of the hardware virtualization capabilities. This means that when using CPUs with first generation hardware virtualization, only the outermost VMM can benefit from the hardware acceleration. While this may not initially seem to be a problem, some modes of operation are not possible without hardware virtualization support, meaning those modes will not be available in a nested-VMM configuration.

Furthermore, some computer manufacturers intentionally disable hardware virtualization support in their PCs, even if the hardware is capable of supporting it.6 The second revision of this hardware support, present in only the newest CPUs at the time of this writing, does allow virtualization of the hardware virtualization instructions, allowing for some degree of nested VMM capabilities.

Limitations and Challenges

Performance There will always be some level of performance overhead associated with hyper visor VMMs. As CPUs evolve to include more hardware support for virtualization, the areas of performance impact will shift from the VMM to the emulated hardware instead, which can still result in a non-trivial impact.

VM inside another VM As mentioned before, unless one uses extremely new hardware it is not possible to run a hardware-accelerated VM inside another hardware-accelerated VM.

No hardware assist Especially important in a virtual desktop solution, one must consider the millions of PCs in the field that could be used as host PCs that do not have even the first generation of virtualization support.7
