Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX-1 is to be stored in a locked A500 steel crate in the dimensions of an average doorframe (92cm wide, 204cm tall and 20cm long) at Site-64. Personnel with up to level 03 clearance are required to ask for permission to experiment with SCP-XXXX-1. The personnel to talk to is limited to scientific personnel with level 04 clearance or higher. The experiment has to be described to said personnel, in order to avoid misuse of SCP-XXXX. In addition to the before mentioned security measures, SCP-XXXX-1 cannot be experimented with in the case of a threat within Site-64 being present, nor can it be experimented with by more than one person or team per day.
Interest in this SCP should generally be kept low, as to circumvent the proposal of large expeditions or proposing to make use of SCP-XXXX as a server for the foundation. As noted by anonymous 04 personnel, this would include a few notable risks. Giving confidential data to not moderatable hardware would most definitely cause a secrecy breach. Additionally, SCP-XXXX may contain self-developing algorithms, similar in fashion to SCP-079. Thus, any not testing-based use of SCP-XXXX is strictly prohibited.
Description: SCP-XXXX is a server farm of unknown scale. It can be accessed through SCP-XXXX-1, a steel door of average proportions and size. Upon entering SCP-XXXX, one will be greeted by a collective of corridors and stairs, all containing unusually tall and fully populated rack-mounts. looking up will reveal the next other level of server racks - depending on the level, the style, size, as well as other descriptive factors of the racks will vary.
When walking to the end of a corridor, its end is pronounced by a metal fence-like structure, about one metre in height. Leaning over said fence will reveal more corridors and a dark, foggy abyss that seems to be made up of dusty exhaust air. About half of all corridors will reveal a set of stairs on one end, while the other half has its set of stairs on the other end. two flights of stairs, each betwen 30 and 40 stairs each, will end in another corridor and a horizontal pass way, used to navigate from one corridor to the other.
looking into a rack will reveal loads of interconnected server-like arrangements of computer components. A large amount of racks is specialized, sometimes being filled with GPUS, other CO-computing cards or an unknown form of what seems to be a high-capicity solid state drive (judging by the visual similarity between said drive and an NVMe storage device) - other, less frequent components have yet to be identified. There is no pattern to this, but every third rack features network switches, CPUs, as well as a wireless data transfer card with an unknown standard.
The systems feature different connectors and bandwidth standards, frequently spiking up to a few trillions of yottabytes per millisecond - if sufficiently cooled. This was measured by using one of the many displays and peripherals which can be found in every fourth level ( including the level SCP-XXXX-1 leads to). The command-based operating system can be operated by a person with at least moderate knowledge of MS-DOS, as shown by a D-Class personnel with, as required, moderate knowledge of MS-DOS. Members from the engineering department were able to open a list of components built into the racks. Said list reveals that physically higher levels usually have more powerful components built into them, as well that levels in other "stacks" (other arrangements of vertically stacked corridors with racks populating them, have yet to be reached) have eiter more or less power-efficient components. Components built into doors facing the outwards side of the door can be heard having their cooling fans loudly buzz. other stacks can be heard quietly operating in the distance, while Stack-00 (starting point for anybody entering SCP-XXXX) is completely silent. It seems to have a 10db background, but no direct noise-floor. the only loud noise audible is an infrequent announcement. In an echoy fashion, it states that new stacks are ready for deployment. After ten seconds of silence, said voice will name the new stacks. The up to five new stacks will receive their name, based on an x/y system, their position relative to stack-00 being the deciding factor.
The servers can be used for any type of workload, including rendering animations and playing Steam games. The performance of SCP-XXXX either suggests that the workload is always perfectly parallelized, or that SCP-XXXX has increadible single- and multi-threaded performance. Opening any file or program can be done by typing in one of two commands. The second, custom one starts with the prefix for opening something, then a space, followed by the name of the program of file. The name can be retrieved by opening a list of all files and then limiting it by typing in letters that fit said file name.
Additionally, several existing components have been discovered to be used in SCP-XXXX. A PCIe hub in level +12 (12 levels above the starting point) was filled with water-cooled GTX-1018TIs, while another rack was populated with Red Rocket CO-processing cards.

[BEGIN LOG]
Beginning: D-Class personnel (from now on referred to as "personnel" only) enters, looks around and swings the camera around at nose level. "This is weird, why am I not given some scientist to talk to?" Personnel opens single rack, pulls out single unit and opens it. "This must be a data center. Why else would there be so enormous motherboards with loads of daughter-boards for additional PCIe slo- no wait, those look different."
~44 minutes later: Personnel had proceeded to wander down first corridor, only to encounter fence after about 3km. "Woah, check this out fellas! There's more, and this display with a keyboard and… mouse? Weird for what looks like MS-DOS." Personnel puts down camera on small flat surface, then starts typing on keyboard. "This OS is called 'Connective', but it sorta works like MS-DOS."
After 30 minutes of typing: Personnel reads through text reminiscent of a manual. "Okay, so we've got stacks. Those are independent systems that all have their connection to one another. Then there's levels. Those are basically what looks like a huge balcony. And then we have the standard stuff, like units and racks. I'll go up now."
After about three hours of exploring, the data size limit is about to step in, forcing Personnel to come back, in order to deliver the much higher resolution footage captured on the camera, as the backup stream was running at 360p and 15fps.
