 Most people install {pve} directly on a local disk. The {pve}
 installation CD offers several options for local disk management, and
 the current default setup uses LVM. The installer let you select a
 single disk for such setup, and uses that disk as physical volume for
-the **V**olume **G**roup (VG) 'pve'. The following output is from a

+Hardware
+~~~~~~~~
+
+We highly recommend to use a hardware RAID controller (with BBU) for
+such setups. This increases performance, provides redundancy, and make
+disk replacements easier (hot-pluggable).

+LVM itself does not need any special hardware, and memory requirements

+Bootloader
+~~~~~~~~~~

+We install two boot loaders by default. The first partition contains
