See QC levels →How we work
Consult & scope
We read your spec, advise on models, budget and timeline.
Spec & price
Our engineer fixes the build; the buyer prices it from vendors.
Contract
Quote, terms and documents — the rate is held, not floating.
Build & QC
Vendor build, then your chosen QC tier with a documented report.
Logistics & customs
Packing, freight and IOR/EOR handled to your emirate.
Delivery
Final inspection and door-to-door handover.
Common problems when buying storage & nas
A chassis you have to populate blind
We quote the array and its drives as one tested system, with capacity and cache confirmed.
Data left on used arrays
Refurbished arrays ship wiped and tested, with a data-erasure certificate on request.
Drives or firmware that won't match your array
We match interface and firmware to your existing OceanStor or PowerVault before build.
