Great Dane Big Nipples After Season

Implementation of a Network for SMEs (2nd Part)

Hi
all, with this note we continue the example of Linux and the creation a network for SMEs.
Following the list of proposed steps: • Create the domain
metalex.com.ar (for use on the network and hosting)
• Acquire a server and prepare the space for it.
• Create a network with IP address according to RFC 1918, DHCP and DNS services.
• Internet Connection Sharing so that any machine has access.
• Install a service domain, which validates users and regulate access to shared resources.

Internet Domain
Fortunately in recent times, most companies (of any scope and size) have become aware benefits to exist and participate in Internet (albeit, only by means of a simple website and email usage).
For the choice of this name should be taken into account the marketing aspects (easy to remember name, catchy and developed as a brand to represent the organization, and to our customer / supplier that is an image of our products and / or services) and technology (not many alphanumeric characters, if possible under 16, while the symbol "-" is the only allowed symbol, I do not recommend their use, and of course the name must begin with a letter).
For these reasons it was proposed to the Company's registration the Internet domain name, metalex.com.ar, as well as metalex.com (always good, as most people tend to put first the domain. com). This was due to pass through several process vary from country to country (for Argentina began the process by nic.ar, through mails). Buy a Server

Turning now to the point of purchasing a server, we are professionals who will be reflected in the choice / recommendation thereof. While Linux uses the resources of a very rational, this means not using anything! Many say Linux works fine on any PC, but I go further, claiming (based on taken the whole experience with computers and servers) Linux works much better optimized for server hardware. Many choose to use powerful PC machines as servers, although in principle this choice seems correct (at least for the initial investment), time will show that NO (the pcs are broken or have a lot more downtime and out of service). Because it is not the same? A server machine will be designed for memory remediation (English ECC Error Correcting Code) processor for servers with more cache and generally more features (like the very popular virtualization), a cabinet to allow proper growth, good ventilation component of best quality and above all, give us the continuity of service necessary to achieve continuous service.
is why I recommend purchasing a recognizable brand server with good local support (such as IBM, HP, Dell, etc., Present in any country), many will say this is expensive or not for us and That is far from reality. This fallacy of thinking that a PC can be a cheap server, comes from comparing the price and not only obtained features. This is shown in the table below

put in this table the most significant, to show that a powerful PC does not serve as a server or at least make it clear that they are very different. Thinking about the box, probably thinking "But I can build a server cheaper than one bought."


Well, first we have to explain ("Leave it clear) is that a clone server, is not a powerful PC. Clone a server should be armed for any home computing or us, with components for server-class (Cabinet with many bays, ECC memory, SCSI / SAS XEON processors and sources that support the daily use). Just look a little mercadolibre see that:

IBM x3200 M2 Server (Argentina U $ S 850), basically for level input, equipped with:

1 1GB Ram 500GB Disk Hot-Swap Sata DVD
1Lector
1 Giga Ethernet Network card
Support: Windows Server 2003 and 2008, Red Hat Linux, Suse LinuxLimited,
1 year Warranty

While buying something similar in the same Free Market:


Cabinet: Intel Server + U $ S300
Motherboard: Intel Xeon U $ S 250 +
Processor: Intel Xeon 3110 U $ S260

+ Memory: 1GB ECC U $ S 120
Storage: 500GB Sata disk is not hot-swat U $ S 180
TOTAL: U $ S1110
result at the end, a lot cheaper IBM server (This is also true for other brands). Also taken into account, the best guarantee for the total group, telephone support (well, that varies from place to place), the best packing server, etc. It really is no point thinking about buying something else.
I recommend doing this exercise with the values \u200b\u200bof their region and secure it again to confirm. They should also be clear about this point of view, in order to defend it before the eyes of a customer who only wants to spend little.
In the next blog will continue to server hardware detail ...

Thanks for reading!
