Archive Storage
Archive storage retains infrequently accessed data at lower cost, with retrieval speed and charges depending on the storage class.
View definitionBlock Size Storage
Storage block size defines the unit used to transfer or allocate data and affects space efficiency and performance.
View definitionCold Storage
Cold storage holds rarely accessed data at reduced storage cost, often with slower retrieval or additional access charges.
View definitionDevice Mapper Multipath
Linux Device Mapper Multipath combines multiple paths to the same SAN volume for failover and optional I/O load balancing.
View definitionErasure Coding
Theerasure coding allocates data and parity to tolerate certain losses with less cost than multiple replication.
View definitionFibre Channel Fabric
A Fibre Channel fabric is a switched storage network connecting servers and arrays with specialized addressing and frame forwarding.
View definitionFibre Channel over Ethernet (FCoE)
Fibre Channel over Ethernet carries Fibre Channel frames over suitable Ethernet networks, typically using lossless Ethernet features.
View definitionFibre Channel Switch
A Fibre Channel switch connects hosts and storage arrays in a SAN and controls frame forwarding and zoning.
View definitionFibre Channel Zone
A Fibre Channel zone restricts communication among selected ports in a SAN fabric, typically using WWPN identifiers.
View definitionFile Storage
File storage organizes data in directories and files that clients access using protocols such as SMB or NFS.
View definitioniSCSI
A protocol that transports SCSI commands over an IP network.
View definitioniSCSI Initiator
An iSCSI initiator is a client that connects to remote block storage targets over an IP network.
View definitioniSCSI Target
An iSCSI target exposes block storage devices or logical units to authorized initiators over an IP network.
View definitionLatency Storage
Storage latency is the time required to complete an input/output operation, typically measured in milliseconds or microseconds.
View definitionLUN Masking
LUN masking limits which logical storage units a SAN array exposes to particular hosts or initiators.
View definitionMPIO
MPIO allows to use several paths to a block storage.
View definitionMultipath
Multipath combines multiple routes to the same storage device to handle path failures and, where supported, distribute I/O.
View definitionMultipathing
Storage multipathing configures multiple access paths to a volume for resilience and, depending on policy, I/O distribution.
View definitionNPIV
N_Port ID Virtualization allows multiple virtual Fibre Channel port identities to share one physical adapter port.
View definitionNVMe over Fabrics (NVMe-oF)
NVMe over Fabrics extends NVMe access to remote storage using transports including TCP, RDMA, and Fibre Channel.
View definitionNVMe/FC
NVMe over Fibre Channel transports NVMe commands across a compatible Fibre Channel fabric to remote storage.
View definitionNVMe/TCP
NVMe/TCP carries NVMe storage commands over standard TCP/IP networks to access remote volumes.
View definitionRAID 0
RAID 0 stripes data across multiple drives to use their capacity and throughput, with no tolerance for a drive failure.
