![]() ![]() Remember that this doesn't represent the data rate, only the number of transfer cycles that the device. Typical dual in-line memory module (DIMM) devices provide 1,066 MT/s, 1,333 MT/s, 1,600 MT/s or 1,866 MT/s transfer rates. ![]() As a brand of Micron, that’s how Crucial® server memory is manufactured. Modern server memory is usually specified using its transfer rate - gauged in millions of transfers per second (MT/s). I generally recommend a /boot of 1GB, a / of 20GB, and a /data which uses the rest of the available space. Optimal quality and reliability is achieved when everything from select silicon to the finished module is tested, monitored throughout production, and tested again before it leaves the fab’s doors. And the cost of downtime is staggering compared to the cost of quality memory. Even if a VizQL session is idle, it is still consuming memory and CPU cycles. When server modules aren’t manufactured start to finish, quality and reliability aren’t as high, opening the door to higher failure rates. Make sure you meet the Tableau Server recommended hardware and software. It just means the module was made elsewhere and rebranded. When you see a server manufacturer’s label on a server module, it doesn’t mean that manufacturer made it. Server manufacturers also don’t make their own memory, they make servers. This matters because third-party brands often claim to be component manufacturers, when they’re actually assemblers who use different components from different suppliers to piece together server modules. There are only three major memory (DRAM) component manufacturers: Micron, Samsung, and SK Hynix. ![]()
