SVCS

SVCS are servers that I use for hosting various network services.

The name "SVCS" is the hostname prefix for presence on the local network. For example, a hostname would be "CTCL-SVCS1". The SVCS name was used since late 2020 from when I first started to use rack mountable servers in a home environment.

Unrelated to hostnames, like most CTCL systems, the hardware has codenames that follow the codename guide. The use of codenames that are of stimulant medications are related to the stimulants' use in the treatment of ADHD and as result, my experience with them for treatment of such.

Currently, the first three systems listed here are part of the HP BladeSystem setup given to me in April 2023.

From February 2023 to the introduction of the HP BladeSystem, the motherboard "Polyethylene" in a Supermicro chassis was used as a temporary solution to be able to sell off the HP ProLiant and Dell PowerEdge systems.

Before "Polyethylene", since late 2020 to early 2023, various 1U/2U Dell PowerEdge and HP ProLiant servers with Intel Xeon Westmere and Nehalem CPUs were used.

"Levoamphetamine"

SVCS1 uses the platform designated "Levoamphetamine" (shorthand "LVA"). The system is currently used for general purpose virtualization.

Specifications as of May 2, 2024

The codename for this device was formerly "Methamphetamine" but was changed to "Levoamphetamine" on February 6, 2024 as a guideline was put into place for codenames. See Week 6, 2024 blog post.

"Lisdexamfetamine"

SVCS2 uses the hardware platform "Lisdexamfetamine" (shorthand "LDX"). This is the oldest BL460c G8 in use, with motherboard components dating to mid-2012. From June 8, 2023 to October 9, 2023, the system reported a motherboard error that was later discovered to just be the BIOS version not supporting the Intel Xeon Ivy Bridge CPUs that I attempted to install on June 8, 2023. After the original E5-2650 Sandy Bridge CPUs were installed, the system operated as normal. This configuration may be used indefinitely due to the difficulty of updating the firmware of these systems.

Currently, as of March 20, 2024, the system is used for ancillary virtualization services including SLAG and other CTCL-developed services.

"Dextroamphetamine"

SVCS3 uses the hardware platform "Dextroamphetamine" (shorthand "DXA"). This system was not put into production until March 2024, one of the reasons for this was that I could not have the system boot to a drive connected to the RAID controller. The fix was relatively simple; all I needed to do was change a setting within HP ORCA to have the system boot from a drive on the RAID controller.

On February 11, 2024, the E5-2643 v2 CPUs where switched for E5-2667 v2 CPUs due to the higher core count and slight increase in single-threaded performance.

On April 5, 2024, a Minecraft server was set up bare metal on this system for use by a college club. 16GB of memory is allocated to the JVM and the server has access to the 16 cores/32 threads of the two E5-2667 v2.

As covered in the blog post for Week 12 of 2024, there has been attempts to run LLMs on this system.

Specifications as of May 2, 2024:

"Serdexmethylphenidate"

In the future, I plan to build "Serdexmethylphenidate" which is a server to take place of the BladeSystem-based hardware. I do not expect to build this system until at least 2026.

Specifications: - Board: Supermicro H12DSi-NT6 - CPUs: 2x AMD EPYC 7343 - Memory: >256GB DDR4-3200 - Case: Supermicro CSE-825
