BMCs and the IPMI Protocol

Image
Baseboard Management Controllers (BMCs) are a type of embedded computer used to provide out-of-band monitoring for desktops and servers. These products are sold under many brand names, including HP iLO, Dell DRAC, Sun ILOM, Fujitsu iRMC, IBM IMM, and Supermicro IPMI. BMCs are often implemented as embedded ARM systems, running Linux and connected directly to the southbridge of the host system's motherboard. Network access is obtained either via 'sideband' access to an existing network card or through a dedicated interface. In addition to being built-in to various motherboards, BMCs are also sold as pluggable modules and PCI cards. Nearly all servers and workstations ship with or support some form of BMC. The Intelligent Platform Management Interface (IPMI) is a collection of specifications that define communication protocols for talking both across a local bus as well as the network. This specification is managed by Intel and currently comes in two flavors, ve...

Understanding How ZFS Calculates Used Space

This document explains how ZFS calculates the amount of used space within a zpool and provides examples of how various ZFS features affect that calculation. DETAILS A ZFS storage pool is a logical collection of devices that provide space for datasets such as filesystems, snapshots and volumes. A zfs pool can be used as a filesystem, i.e. such as mounting/unmounting; to take snapshots that provides read-only (clones are writable copies of snapshots) copies of the filesystem taken in the past; to create volumes that can be accessed as a raw and a block device and for setting properties on datasets. Interaction of all these datasets and associated properties such as quotas, reservations, compression and deduplication (Solaris 11 only) play a role in how ZFS calculates space usage. Neither the du nor df command have been updated to account for ZFS file system space usage. When calculating zfs space usage, always use the following command. # zfs list -r -o space <pool_name...
