| File Storage |
A Storage method where data is managed as a discrete file within the operating system's filesystem. It is very common on workstations, servers, and NAS devices |
| Block Storage |
The Storage method that breaks data into chunks and distributes the chunks across available storage space, independent of the server's filesystem. |
| Object Storage |
A storage method where data is broken into chunks and managed with detailed metadata. It is very scalable and is best for data that is written once and read often. |
| Storage Area Network |
Network dedicated to provisioning storage resources, typically consisting of storage devices and servers connected to switches via host bus adapters. |
| Logical Volume Manager (LVM) |
Software that maps physical devices and partitions to logical volumes |
| Scalability |
Property by which a computing environment can gracefully fulfill its ever-increasing resource needs |
| Master Boot Record |
Sector on a mass storage devices that hold information about partitions and the OS Boot Loader |
| GUID Partition Table (GPT) |
Modern Disk partitioning system allowing large numbers of partitions and very large partition sizes |
| Unified Extensible Firmware Interface (UEFI) |
Type of system firmware, providing support for 64-bit cpu operation at boot, full GUI and mouse operation at boot and better boot security |
| Filesystem in Userspace (FUSE) |
Permits the creation of non-privileged access to the kernel by providing an interface between the two |
| Userspace |
The area in system memory outside of the kernel space that includes software that accesses kernel services |
| Latency |
Time Taken for a singnal to reach the recipent, measured in milliseconds. Latency is a particular problem for two-way applicaitons, such as VoIP and online confrencing. |
| Throughput |
Amount of data transfer supported by a link in typical conditions. |
| RAID |
Specifications that support redundancy and fault tolerance for different configurations of multiple-deivce storage systems. |
| Input/Ouput Operations Per Second (IOPS) |
Preformacne indicator that measure the time taken to complete read/write operations |
| Multipathing |
Overprovisoning controllers and cabling so that a host server has failover connections to networks and storage media |
| Storage Area Network |
Network Dedicated to provisioning storage resouces |
| Fiber Channel |
High Speed netwwork communications protocol used to implement SAN's |
| Internet Small Computers System Interface (iSCSI) |
IP tunneling protocol that enables the transfer of SCSI data over an IP-Based network to create a SAN |
