The Biggest Movie Server

[Nella Mcnairy]

Nowadayshumankind produces over 2.5 million terabytes of datum daily. And the pace and volume will grow even more in the future, since the IoT (Internet of things) is on the increase daily. Special facilities called DCs (data centers) are created to store such volumes of information. And their powers and territories grow regularly.

The development of machine learning and artificial intelligence has made our world data-driven. Nowadays, the number of data centers on Earth exceeds 7 million facilities. They differ in size and computing power and are designed for processing either industrial or small operations.

This is the largest server room in the world, which is located in the USA. The DC is based in Las Vegas and occupies a territory of 7,750,015 square feet. Switch is the owner of the facility, which has patented over 260 technology in the sphere of network and IT development. Due to the ownership of such a reputable service provider, the facility features the following:

This is the greatest data command office of Apple. Although the company was originally built by First Solar Inc., further, Apple invested $2 billion in the development of the facility and started to use it. The DC is located in Arizona and occupies a territory of 1,300,000 square feet.

This is another impressive data center located in the USA. Digital Reality owns it. An investment trust that owns more than 280 DC facilities around the world. This one is the most prominent. It is built on an area of 1,100,000 square feet. Nowadays, the facility offers capacities for financial institutions around the world, allows the processing of different kinds of financial data, and provides reliable storage secured by advanced certificates.

The building houses 3 electric power feeds that generate more than 100 MW of power and 4 fiber vaults. Its cooling strategy is one of the distinctive features of the company. The facility is equipped with an 8.5-million gallon tank filled with a chilled brine-like substance. A branched system of pipes allows the liquid to flow through the building, cooling down server rooms and accommodating equipment.

The main purpose of the facility is to support the efforts of the Intelligence Community to develop, strengthen, protect, and improve the security of the intellectual property of the nation. The facility is located on an area of 1,000,000 square feet. Here, a data center and all the servicing units (such as energy generators, chiller plants, fire hoses, etc.) are placed.

This DC occupies a territory of 990,000 square feet, on which not only the main unit but also all the required supplementary bodies are located. The main building consists of numerous server rooms and also accommodates 24 independent UPS systems and 46 generators.

To improve the level of security and system smooth functioning, advanced systems of climatic control are used. Sensors are designed to monitor the level of temperature, pressure, water, humidity, and other crucial indicators.

This data center is located in India. An advanced multi-tier facility occupies an area of 970,000 square feet. The company generates 100 MW of power to maintain performance and is large enough to accommodate up to 12,000 racks.

The main aim of the facility is to make DC services more accessible in the region, improved effectiveness, and provide customers with powerful systems that are able to process tasks of any complexity.

This company is based in Northern Virginia and includes three data centers, named VA1, VA2, and VA3. The last one is the biggest and takes an area of 940,000 square feet. The facility provides capacities for all kinds of operations related to cloud and network performance. The service provider cooperates with major companies around the world.

The building is equipped with advanced systems for environmental control, integrated ventilation systems, and optical solutions for cooling. The facility guarantees secure storage of data and high standards of performance. These are the most prominent and well-known data centers scattered throughout the world. Each of them is designed to perform certain tasks and cater to different groups of consumers (financial institutions, businesses, manufacturers, etc.). The above-mentioned facilities produce a lot of capacities to satisfy the high computing demands of modern enterprises.

I suggest you to use baobab, which will give you a graphical overview of your disk usage. It can also be used for remote folder (through ssh, ftp,...) to scan the disk usage on a remote server for instance.

Edit: If you would like to investigate the disk usage directly on the server with your shell access and not remotely, and you would like a tool more convenient than du, you can also have a try with durep which will generate a report of the disk usage with bar graphs.

I'm regularly running du -dak > du-dak.out at the top of each file system. Then, I can get a graphical display with xdu It was back in my early years as a junior SQL Server Guru. I was racing around Enterprise Manager, performing a few admin duties. You know how it is, checking a few logs, ensuring the backups ran ok, a little database housekeeping, pretty much going about business on autopilot and hitting the enter key on the usual prompts that pop up.

Needless to say a world record was promptly set for the fastest database restore to a new database, swiftly followed by a table migration, oh yeah. Everyone else was none the wiser of course but still a valuable lesson learnt. Concentrate!

(2) is the default isolation level and (imho) the lesser of two evils. But it's a huge problem for any long-running process. I had to do a batch load of data and could only do it out of hours because it killed the website while it was running (it took 10-20 minutes as it was inserting half a million records).

Oracle on the other hand has MVCC. This basically means every transaction will see a consistent view of the data. They won't see uncommitted data (unless you set the isolation level to do that). Nor do they block on uncommitted transactions (I was stunned at the idea an allegedly enterprise database would consider this acceptable on a concurrency basis).

One of my favorites happened in an automated import when the client changed the data structure without telling us first. The Social Security number column and the amount of money we were to pay the person got switched. Luckily we found it before the system tried to pay someone his social security number. We now have checks in automated imports that look for funny data before running and stop it if the data seems odd.

We had an old application that didn't handle syncing with our HR database for name updates very efficiently, mainly due to the way they keyed in changes to titles. Anyway, a certain woman got married, and I had to write a database change request to update her last name, I forgot the where clause and everyone in said application's name was now Allison Smith.

The biggest mistake was giving developers "write" access to the production DBmany DEV and TEST records were inserted / overwritten and backup- ed too production until it was wisely suggested (by me!) to only allow read access!

Sort of SQL-server related. I remember learning about how important it is to always dispose of a SqlDataReader. I had a system that worked fine in development, and happened to be running against the ERP database. In production, it brought down the database because I assumed it was enough to close SqlConnection, and had hundreds, if not thousands of open connections.

At the start of my co-op term I ended up expiring access to everyone who used this particular system (which was used by a lot of applications in my Province). In my defense, I was new to SQL Server Management Studio and didn't know that you could 'open' tables and edit specific entries with a sql statement.

I expired all the user access with a simple UPDATE statement (access to this application was given by a user account on the SQL box as well as a specific entry in an access table) but when I went to highlight that very statement and run it, I didn't include the WHERE clause.

A common mistake I'm told. The quick fix was unexpire everyones accounts (including accounts that were supposed to be expired) until the database could be backed up. Now I either open tables and select specific entries with SQL or I wrap absolutely everything inside a transaction followed by an immediate rollback.

Not, exactly a "mistake" but back when I was first learning PHP and MYSQL I would spend hours daily, trying to figure out why my code was not working, not knowing that I had the wrong password/username/host/database credentials to my SQL database. You cant believe how much time I wasted on that, and to make it even worse this was not a one time incident. But LOL, its all good, it builds character.

I updated a table schema in a production environment. Not understanding at the time that stored procedures that use SELECT * must be recompiled to pickup new fields, I proceeded to spend the next eight hours trying to figure out why the stored procedure that performed a key piece of work kept failing. Only after a server reboot did I clue in.

A healthy amount of years ago I was working on a clients site, that had a nice script to clear the dev environment of all orders, carts and customers.. to ease up testing, so I of course put the damn script on the productions server query analyzer and ran it.

I set the maximum server memory to 0. I was thinking at the time that would automatically tell SQL server to use all available memory (It was early). No such luck. SQL server decided to use only 16 MB and I had to connect in single user mode to get the setting changed back.
