What hosts are limited to 2TB?
This is a hard question to answer completely. Generally, older 32-bit operating systems like Windows XP will not handle drives with more than 2^32 – 1 sectors, or the biggest sector number that can be represented in 32 bits (roughly 4 billion sectors). When using 512 byte sectors this results in a 2TB drive-size limit. For a variety of technical and compatibility reasons, Tableau MSS units will only use 512 byte sectors. So, any operating system or driver which handles only 32-bit sector numbers will be subject to the 2TB limit. Even if you are using a modern operating system, certain device drivers from independent hardware manufacturers (e.g., some eSATA add-in card manufacturers) won’t correctly handle sector number larger than 32-bits. We recommend you specifically check to make sure your operating system and device drivers correctly handle drives larger than 2TB.
