LUN storage configuration has long been a cornerstone of storage management. The LUN – a chunk of storage created from RAID partitions on a SAN – presents a logical volume of capacity to an individual server.
That’s still relevant today in the era of virtualisation. Many users retain physical servers that need a one-to-one connection between host and LUN. But, the role of the LUN is also changing with the rise of server and desktop virtualisation. It now forms a container for the logical objects used by VMware, Microsoft Hyper-V etc.
In this guide you will find all you need to know about LUNs, LUN configuration and management, including their use in virtualised environments.
