Regulation on the Procedures and Principles for the Transfer of Personal Data Abroad (Kişisel Verilerin Yurt Dışına Aktarılmasına İlişkin Usul ve Esaslar Hakkında Yönetmelik)

If SoSo CAD uses foreign sub-processors (cloud, email, monitoring), maintain an unmodified KVKK standard contract for each transfer path.

• Standard contracts are published by the Board and must be used without modification (Article 14(2)-(3)).

Know specific, unique applications of generators in mission critical facilities

Generator catalogue entries need kW/kVA at 0.8 PF plus derating inputs; the tool should auto-derate for site altitude and design ambient.

• Emergency systems require selective coordination (NEC 700.30).

Consulting-Specifying Engineer · 2026

Know the electrical, power components in a data center

Seed facility-type templates with default UPS/generator redundancy and fuel autonomy from Table 1.

• Generators should be loaded to at least 30% to avoid wet stacking.

Energy efficiency in HVAC systems with dry-cooler free-cooling applications (Kuru Soğutuculu Doğal Soğutma Uygulamaları ile İklimlendirme Sistemlerinde Enerji Verimliliği)

Use the paper's mode thresholds (approach of about 2 C for partial and about 5 C for full free cooling) as defaults in a free-cooling-hours estimator, fed by city bin data for Turkish sites.

• Targets 24/7 loads such as server rooms and data centres.

Learning from the OVHcloud data center fire

Separate UPS and battery rooms with fire-rated barriers.

• NFPA 75 and NFPA 76 are the related standards.

Let's Wait Awhile: How Temporal Workload Shifting Can Reduce Carbon Emissions in the Cloud

For carbon and sustainability reporting, use hourly (not annual average) grid carbon-intensity profiles per region.

• Batch jobs make up 60% of processing on large clusters, and more than 40% of these run daily.

Leveraging Intelligent PDUs and Monitoring: Rack Power Solutions for Modern AI Applications

In the rack-power calculator, offer inlet presets (voltage, amps, plug), apply 80 % continuous derating and show kW per feed.

• Saf-D-Grid and RF-203 outlets support 480/277 V operation.

Liquid Cooling - Exponentially increasing power density: At what pace should Liquid Cooling be implemented?

Define rack templates per GPU generation with a default kW and liquid/air split, for example 85/15 at 130 kW and 100/0 at 600 kW.

• 600 kW racks require 100 % liquid cooling.

Liquid Cooling - When performance meets sustainability: the data center cooling challenge

In the CDU selection tool let users trade approach temperature against heat-exchanger area and TCS delta-T, with Cases 1-3 as validation fixtures.

• Case 2: same duty with APT 2 K needs 143.6 m2 (double).

Liquid Cooling Commissioning: Lessons Learned @LRZ (EE HPC WG session, SC13)

In commissioning checklists the tool generates for liquid-cooled plants, include verification that instrumentation matches manufacturer specifications.

• LRZ runs four loops: warm water 30/36 C, cold water 14/20 C, very cold water 4/10 C, plus a glycol/heating loop.

ASHRAE · 2013

Liquid Cooling Guidelines for Datacom Equipment Centers, 2nd ed. (ASHRAE Datacom Series Book 4)

In the DLC data model, keep facility water (FWS) and technology cooling system (TCS) loops separate, with a CDU as the interface.

• Authored by ASHRAE TC 9.9.

Liquid Cooling Retrofits: Hard, but Sometimes Worth It (Christopher Tozzi)

Add a retrofit check comparing liquid-cooled rack weight (default up to about 3,000 lb / 1,360 kg) with the raised-floor rating.

• Fully loaded AI racks with liquid cooling can exceed 3,000 lb, which raised floors may not support without reinforcement.

Liquid Cooling Whitepaper - End-to-End Cooling: The Key to Resilient AI Data Centers

In the liquid-cooling module size TCS flow at about 1.5 L/min/kW by default and store CDU approach temperature and external static pressure.

• Rack heat densities from about 125 kW today to beyond 500 kW.

Lithium Batteries for UPS Applications: Battery Management and Chemistry Choices Pave the Way

Add cathode chemistry, oxygen-release flag, float life, maximum charge C-rate and BMS disconnect limits (V, I, T) to the battery catalogue.

• Thermal runaway can reach 300-500 C; LFP does not release oxygen at those temperatures and is the safer choice.
