Storage clusters that survive in production.
Ceph, all-flash, hybrid, or pure capacity tier — we design storage clusters around your workload, not around a vendor's reference architecture. Hardware, software, network fabric, integrated and tuned end-to-end. From a single 24-bay node to multi-petabyte clusters running thousands of VMs.
Three things that matter at petabyte scale.
Storage is where the wrong decision shows up two years later, not two weeks. We've operated clusters long enough to know what the second-year failure modes look like.
Storage architectures we have shipped.
Every architecture below has a reference design we've put into production. We start from a known-good baseline and tune for your workload — performance, capacity, durability, or the right blend.
What we've put into production.
Two storage clusters operating live today — one running thousands of VMs in a major Hong Kong IDC, one a multi-petabyte cluster scaled with us through two generations of fabric.
Ceph cluster running 4,000+ production VMs in a major HK datacenter.
Akari operates one of Hong Kong's larger IDCs. Their virtualization platform requires a storage backend that can handle thousands of VMs concurrently — boot storms, mixed read/write profiles, snapshots, live migrations — without latency excursions that translate into customer-visible problems.
Scope: Ceph cluster design, hardware spec across multiple node types (block, object, metadata), failure-domain layout aligned to physical rack topology, performance tuning for hypervisor I/O patterns, ongoing capacity planning as the VM fleet grew.
Multi-petabyte capacity cluster, scaled across two fabric generations.
39ai's storage cluster grew with the AI workload. We built the original 12-node deployment on a 25G fabric, then scaled it out and upgraded the fabric to 100G as throughput demands climbed.
Today's footprint: 14 × Supermicro 24-bay chassis, mixed disk loadout — 120 × 22TB drives plus 9 × 24 × 24TB drives for the high-density tier. Full 100G inter-node fabric. The same team designed the original cluster, the scale-out, and the fabric migration.
