Software Tips and Tricks from the Pros

Make your time with RV Dealership Software more efficient.  Our developers and testers would like to offer some tips and tricks to help you use your software suite to its full potential.

  1. Can’t remember a code?  Any underlined heading on a page acts as a link to a search window.  For example, search for a customer ID by entering the customer’s first and/or last name. Or, search for a product number by entering a partial description of the product.

  2. Sort it out.  When viewing a list of items to select from, you can sort the list by  a column, simply by clicking on the blue heading you wish to sort by.

For example, this screen shot shows a list of work orders sorted by work order stage.  To sort by WO date, click the blue column heading for WO date.

 

  • Four of a kind.  When setting-up, updating, and using most of the tables in RV Dealership the “-“, “+”, “x” and “>” buttons will always be helpful.  Add or subtract a line to the bottom of a list easily or insert or delete specific rows within your list.

- = deletes the bottom row of the list

                   + = adds a row to the bottom of the list

                   x = deletes the specific row highlighted

                   > = inserts a row above the current row


Understanding Server Upgrades

Peartree recommends certain minimum requirements in terms of hardware requirements when a new customer decides to implement RV Dealership Software, or when an existing customer chooses to migrate from our legacy version to the web-based version of our software.  This article will explain why we recommend certain servers with particular upgrade components.  For you, this may mean upgrading your existing server, or purchasing a new one.

Memory

Servers should be upgraded to at least 1 GB of RAM memory as this allows your server to run more processes and withstand the strain of running constantly. Servers are meant to run 24/7, and not be shut down; increasing RAM memory to at least 1 GB ensures your server will be able to provide the processing power you need.

Licenses and Software

An upgrade that needs to be made for a newly purchased server is a licensing upgrade through the purchase of an extra 5 pack (possibly more depending on number of users) of Windows software licenses. This ensures you will be in legal compliance with the Microsoft Software License Agreement; you need a separate license for each computer system you have attached to your server.

Software for your server is also an add-on to the standard Dell server. These include corporate anti-virus for your server that can then be run on all the computers attached to that server. Your Peartree Software IT Consultant will configure the software your system needs and include these costs in your Peartree hardware quote.

Back-up

An important upgrade Peartree Software recommends for every new server is a solid back-up system. The recommended additions include a Tape Back-up system such as the Power Vault 100T, which provides extra memory to back up all the files on your server every night to prevent data loss should anything happen to your server or your network system. To create these back-ups extra software is also required. VERITAS Backup Exec SBS is a small business protection suite that Peartree will include in your quote to ensure that you are truly protected from data loss.

Part of this back-up system also includes additional hard drives for your server. The standard is one hard drive, but Peartree IT Consultants strongly recommend that this is upgraded to at least two. Multiple hard drives allow mirroring to protect against drive failure and provide extra back-up in case of a drive failure.

Power Safety

As previously mentioned, servers are meant to remain on all the time. A power failure, causing a sudden server shut-off could spell disaster for your server. Shutting down a server takes time to allow for every system to shutdown properly to prevent hardware damage and data loss. Peartree Software recommends a UPS driver be purchased with your system to ensure that if a sudden power failure should occur your server will have enough back-up power to allow it to be properly and safely shutdown. This means your hardware, software, and data will all be secure.

Warranties

A critical additional upgrade for your server  is an extended warranty. You are investing in an important piece of hardware for your business, and Peartree wants it to be protected with a strong warranty in case anything goes wrong with your system.

The standard warranty included with a new Dell server is one year. Peartree Software upgrades this to a minimum of three years, Next Business Day Parts and Labour On-site from Dell. This means if there are any problems with your hardware, the down-time will be minimal, parts will arrive the next day, and it will be covered by Dell for at least three years.

 

It is important to know all the information to feel comfortable with your server purchase and to understand all the differences between a base model and what upgrades to the base model will mean for you and your business.  Peartree Software wants you the have the best quality hardware possible. We also want all the hardware on your site to be everything it needs to be to serve your needs, protect your data, and provide the performance you expect.


Servers versus Workstations: What you need for the job

Excerpts from Harry Brelsford’s article “Server versus Workstation: The right tool for the right job”, Published April 1999 in his book “Regular” Windows NT Server from IDG Books.

When deciding on the hardware you need create the best system for your dealership there are many different options to choose between.  To run your Peartree RV Dealership software a dealership must have a dedicated server with minimum speed and memory requirements.  Peartree can provide your business with the hardware it needs as a reseller of Dell computers, servers, and equipment. 

Many people confuse the difference between servers and workstations and do not understand the requirements a server must have to meet the demands software.

So what’s the difference? They may seem subtle, but a failure to grasp the difference could have you looking at the blue screen of death more than you should. The following is a brief comparison of a Server and a Workstation.

Aren’t they the same? The short answer is yes and no. They are nearly identical by most appearances.  And no, because they are tuned very differently and are designed to scale to different mountains.  NT Workstation is tuned to provide the best possible performance for a single interactive desktop user. NT Server, however, is tuned to provide great performance when used as a server operating system, with lots of users requesting lots of files from the server.

Tuning Issues

There are fundamental architectural-level differences existed between Windows NT Server and Workstation. One difference in particular lay in how to “tune” the Server version for performance vis-à-vis how to tune the Workstation version.

  • Task scheduling. NT Workstation provides speed in starting and ending multiple tasks during a session. NT Server enables focus on serving network requests without interrupting other services that may be running.

  • Memory allocation. The applications that are loaded generally are for multiple use and generally do not get unloaded that often, the OS in Server grants the maximum requested RAM if it’s available.

  • I/O throughput. Multiple queues and threads are dedicated to this task in Server. Server is even designed to allow sharing network loads among other servers in a cluster. In Workstation, only one queue is assigned to dealing with network requests.

  • File cache. Memory is prioritized differently on Server and Workstation. In Server, the file cache is given the highest memory priority. In Workstation, it’s given a lower priority.

Processors
Workstation can use only two processors as shipped; it can support up to 32 processors, but you’ll need to find a customized Hardware Abstraction Layer (HAL) from Microsoft or your hardware vendor. In any case, it makes little sense to do this with the obvious additional costs given the design benefits already programmed into Server. Server can handle up to four CPUs right out of the box.

Clustering
Clustering, or using multiple servers to share the network file and application load in a fault-tolerant manner, is an important feature for small and medium businesses. NT Server is designed to support this feature; Workstation is not.

Client connections
Can a company reliably load up Workstation with more than its maximum of 10 users? No. It doesn’t work. Not only is a license limit invoked, causing user 11 to get access denied, but also putting that load on Workstation’s background server processes brings it to a crawl. Server can handle an unlimited number of simultaneous network client connections.

Security
NT Server has a full-domain security model implemented. It can act as both primary and backup domain controllers. Workstation can only authenticate users in the older “Workgroup” model. A Windows NT Server controller is required to authenticate in the domain model.

File system support
Workstations file system processes are not optimized to serve up large files to even its stated 10-user network client limit. Server meanwhile is geared up to serve files all day long in a client/server mode.

Internet Server services
NT Workstation 4.0 comes with a nifty Web server called “Peer Web Services” or PWS for short. Basically, this is a scaled-down version of Internet Information Server so that Web administrators can “model” an Internet or intranet site on the local LAN. It needs to be upgraded to 3.0 or 4.0 before it’s ready for prime time in the surf universe.
