# 1 PB Cithorum Cloud Pod — Architecture Summary

## What is live

Cithorum operates a live 1 PB Cithorum Cloud pod in India. It is the proof and delivery environment for Jam-compressed managed storage, buyer pilots, restore drills, and the first Data-Centre Ops KG work.

## Current source-of-truth spec

- 5x Supermicro AS-1115HS-TNR storage nodes
- 1 control / GPU node
- EPYC 7313P
- 256 GB DDR4 per storage node
- 8x Samsung PM9A3 30.72 TB NVMe per storage node
- Mellanox SN2700 top-of-rack switching
- ConnectX-5 networking
- Erasure coding: k=4, m=1
- 1.23 PB raw / ~983 TB usable

## Buyer-facing capabilities

- S3-compatible object storage
- Jam-compressed backup and archive tier
- Block and file service path for compute-adjacent workloads
- Restore in seconds, not cold-tier hours
- $0 Cithorum egress fee
- Data-Centre Ops KG telemetry path for benchmark reports, restore proof, and billing exports

## Economics

- $5/TB-month managed-storage benchmark for qualified public scenarios.
- Up to ~80% below AWS S3 Standard list storage pricing on qualified storage scenarios.
- ~45% lower facility energy versus conventional storage in the 1 PB pod reference.
- More effective capacity on existing CPU and storage before expansion capex.
- $0 egress fees.
- AWS S3 Standard is a list-rate reference. Comparisons exclude request, retrieval, transfer, tax, committed-discount, SLA, and region-specific scope differences.

## Boundary

This summary is the buyer-facing version. Deeper BOM, supplier, power, rack, network, security, and tender-specific material now lives in the served document library where it is useful, with legacy material separated from current positioning.
