Hello, I've got a question re. disk performance for SQL and Exchange running on a SAN.<br />
<br />
With a SAN with a fair amount (16GB) of cache, and using 4Gb Fibre links, is it still necessary to split the Logs files and Databases over different arrays like it used to be with local storage?<br />
<br />
I realise its probably down to the amount of traffic the servers are processing, but I was just wondering from a 'rule of thumb' point of view.<br />
<br />
Many thanks.<br />

SQL and Exchange DBs and Logs on SAN

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage
