Welcome welcome welcome to the world of the Internet in Australia. Even in our largest population center, we can struggle to get 3Mbps downstream on a business-class ADSL2+ connection. Cable penetration is poor in residential areas, and even worse in commercial so unless you're fortunate you can't get cable internet. And because we're such a sparse ...

It's really difficult to buy an unsuitable rack today if you're purchasing new. I usually encounter generic, custom or unbranded racks, APC Netshelter, Dell and HP (10642 G1 and G2 models) in the field. They've all been solid and have handled the systems and equipment I've needed to mount within them. The basics: Begin with your servers. Why not match ...

If you're willing to spend a little money, you can get the "bible" for cabling installers: The "Information Transport Systems Installation Methods Manual" from BICSI. It's $129.00, but it's got an unbelievable amount of detailed information. If you're worried about legal compliance, check with your local electrical or building inspector. Most states don't ...

It refers to the technologies used that make up your service: your web application language/framework depends on (is stacked on) your web server, which talks to (stacks on) a specific database flavor, and these run on (stack with) specific operating systems. So you might have a stack like this: P PHP M MySQL A Apache L Linux to make up the LAMP stack, or ...

Considering you're upgrading from tables to a rack, you don't need to get too fancy with it. Accessories: Doors, Front Very handy for keeping questing fingers from pressing buttons (or pulling levers) they shouldn't. Also makes for a neater appearance; that can actually count for things! Should be fully perforated, I don't think they're even selling ...

I'm no expert either but I'm on board with what you've stated in your question. My opinion is that the vendor is giving you a snow job in order to make more money off of the job by selling you CAT6 cable. My recommendation is that unless you plan on moving to 10GbE (CAT6a cable needed) in the near future then stick with CAT5e. GbE (1000BASE-T) will happily ...

This company charges us around 650 USD / month and we don't feel the service they provide is worth the money. $650/mo is peanuts. A full-time staffer will cost you 5 times that much minimum - 8x or more is more likely, especially when you consider benefits, equipment, payroll taxes, and office space in the mix. From the other direction, a typical ...

Keep track of the time you spend updating /etc/hosts files, deploying the changes and keeping them in sync.

In general this mean the technologies used to deliver the product. So in the case of Stack Exchange (formally known as Stack Overflow), we say we use a Windows Stack even though there is some Linux because we use SQL Server, Windows IIS, and .Net

Higher Availability As Chris mentions, your API server is the single point of failure in your layout. What you're setting up is a message queuing infrastructure, something many people have implemented before. Continue down the same path You mention receiving requests on the API server and insert the job into a MySQL DB running on each server. If you ...

I primarily work with an application that has zero horizontal scaling potential. Even though it runs on Linux, the application, data structures and I/O requirements force me to "scale up" onto progressively larger systems in order to accommodate increased user workloads. Many legacy line-of-business and transactional applications have these types of ...

We're using it for 7+GB of data per day, but we pay for that. A lot. I think we get a bit of an academic discount, but mostly we managed to justify spending the money because it satisfied auditors about having somebody/something looking over our logs. We also use nagios. We've configured nagios with some saved searches that call scripts that either ...

A router needs to be sized for the load it is expected to handle. In our campus network, the big 6500's in the middle of the networks are orders of magnitude more powerful than the router that links us to our ISPs. This is because most of our generated traffic is internal oriented. That border device is shoveling around 500Mb/s, but the backplane on our core ...

Read the wikipedia articles on this stuff. There is no real advantage of cat6 over cat5e. Specifically, both can run gig ethernet the same distances and when you go to 10gig ethernet, neither is 100% guaranteed to work. If you want to be able to run 10gig ethernet over copper, you need a 100% cat6A cable plant, not just cat6. With cat6, you can run up to ...

Generally speaking I ask software developers the same question I would ask anyone else: "What are you trying to accomplish here?" and How can I help?. To break that down a little more and give you some ideas to start you out: Ideally you should start at the highest of high-level overviews: What is the purpose of the company? Next the question that starts ...

I've used a number of different racks and while they all did the job, some are distinctly better than others. I strongly recommend staying clear of any rack that uses round mounting holes (I inherited, so it wasn't my choice). Two things stand out for me as really important. The depth. I've had more than one rack where I couldn't fit the rear door because ...

Wow, that's an enormously broad question :) It's quite off-topic for serverfault, so it'll probably be closed in a bit. But as it's saturday afternoon, I'm in a storytelling mood, so here's an answer, roughly based on a simplified version of how we grew the company I currently work at. The abbreviated answer is my favourite: It depends. There is no "this is ...

Hooo boy. Where to start... You probably want switches in each of the distant buildings, you don't want to have to run a new line from the central building every time you expand a different building. Then, you need to work with facilities and/or contractors to get cables strung between buildings. There's probably existing buried tunnels/pipes with other ...

+1 for MikeyB's answer. As an extension, how would you convince a corporation that they need anything else? (How to justify the need for a new rack or switch, etc.?) Compare the alternatives, and provide a cost/benefit analysis for each option. It really doesn't take that long to setup a reliable DNS solution. Beyond the test necessary to update ...

Your assumptions are wrong - no public CA will issue you a certificate to use as your root certificate. You generate your own, self signed certificate authority and distribute it to clients to make them trust you. Then you use that to sign your certificates. All public CAs are self signed - they are included in your OS or browser because the OS vendor ...

For a typical high-tech office with less than 50 people, run 3 CAT6 cables to every office or workstation and terminate them as RJ45 walljacks. Make them all home runs back to your server room. If you are using IP phones, terminate them all to RJ45 patch panels in a 2-post rack with your switches. If you aren't using IP phones, terminate 1 out of each ...

Make the swap / paging file a fixed size. This will eliminate the overhead of auto-growing the paging file. It also reduces fragmentation. Control Panel -> System -> Advanced -> Performance Settings -> Advanced -> Change. In the windows performance settings, Control Panel -> System -> Advanced -> Performance Settings, turn off all of the cute effects, ...

First off, Joel is correct: For competent IT support you're looking at a higher cost. The bottom end of the IT pro market is saturated with self-taught people working from home. The price is good, but the attention to detail, professionalism and consistency isn't there, and there's the tendency to do things 'my way' rather than adhere to best-practices (or ...

When they need it. When it's cheaper to hire someone and buy stuff than it is to subscribe to a service. When they want something that's not "off the rack." I've heard of someone running a small business off an ipad. I've talked to someone else who's very interested in possibly colo-ing SQL for their one person company. To answer your specific ...

From a developer perspective I can say that nearly every traditional mainstream database engine out there can only scale up and scaling out is very much an after thought. In recent years with the need for greater scalability and highly available systems there have been efforts to make existing databases scale out. But because the designs are hindered by ...

There is a reason why large enterprises use Active Directory. It makes more sense. Things to consider: If I compromise your computer, you've either got different passwords everywhere, which means you likely have passwords stored somewhere or you're going to re-use the same password. Not everyone is going to have a decent password vault. In either case, I'm ...

You don't say how you've bundled them together. Did you use zip ties and pull them tight? Did you loop the cable and cinch the loop (like a figure eight)? Are there any other places where there are sharp bends? How small is the radius of the loops or bends? You don't say whether they're pulled through walls or drop ceilings. You don't say what the ...

I started drawing a chart to show our IT department but as there is only one of me it just ended up looking like a circle.

Cables are easier to trace, and space is used much more efficiently in Option 2. Crosstalk increases when longer cables are tightly bundled, so you should have LESS with the short ones, even if they were switch-to-switch. Ensure cables at back of patch panel are routed to leave room for easy switch insertion. It works well for us. My only question: ...

Potential catches/hurdles: Bandwidth: When you talk about moving bandwidth-intensive services like database and file servers offsite, you need to take a long look at how fat a pipe you would need to maintain your existing level of performance. Depending on the type of institution that you represent, you may or may not already have gigabit or 10-gigabit ...
