Appliance by Greenbytes based on X4540
The startup Greenbytes developed an appliance on the foundation of the X4540. It looks like a combined deduplication and MAID device. But there is an error in the article.
Greenbytes sells its software running on a SunFire 4540 system from Sun Microsystems. The Sun system packs as much as 90 Tbytes of hard disk storage and 64 Gbytes RAM in a single x86-based rack mounted computer.
You have 48 native TB in the chassis, not 90 ones. But i assume, we will be near of 90 TB in a year or so (even notebook drives have 500 GB nowadays …)
