Terms/Vocab Flashcards
What is dedupe?
Dedupe (short for deduplication) is a data processing technique that eliminates duplicate copies of data to improve storage space and efficiency.
What is TOE?
TCP Offload engine. A technology in NICs that shifts TCP processing tasks from the CPU to the network adapter, improving performance and efficiency.
What is TLS?
Transport layer security. It is a protocol that encrypts and secures data transmitted over a network, ensuring privacy, authentication, and data integrity.
What is RDMA?
Remote Direct memory access. Allows one computer to directly access the memory of another computer without involving the CPU or OS of the remote computer.
What is iWARP?
Internet wide area RDMA protocol. Enables RDMA over TCP/IP networks, allowing for high speed data transfers with low latency.
What is TCP?
Transmission control protocol. Manaages the transmission of data between computers over a network.
What is iSCSI?
Internet small computer systems interface. Protocol that enables block-level storage access over an IP network, allowing servers to use remote storage devices as if they were locally connected.
What is SAN?
Storage area network. Consolidated, block level storage that allows multiple servers to connect to shared storage devices.
What is NAS?
Network attached storage. Centralized storage system connected to a network that allows multiple users and devices to access, share, and manage files from a single location.
What is NFS?
Network file system. Protocol that allows files to be accessed and managed over a network as if they were on a local disk.
What is NVMe?
Non-volatile memory express. Connects SSDs to a computer via PCIe. Faster data access, lower latency, improved performance.
What is NVMe-oF?
NVME over Fabrics. Allows NVMe storage devices to be accessed over a network. High speed and low latency.
What are network fabrics?
Ethernet, Fibre Channel, Infiniband.
What is ethernet fabric?
Uses ethernet switches and sables to create networks for data centers. Used with iSCSI and NFS. Broad range of applications. General data center applications.
What is Fibre Channel?
Specializes in storage area networks (SANs) , offering data storage transfer for storage systems. Used with FCoE. Commonly used in enterprise SANs with strong data integrity.
What is Infiniband?
Provided interconnects for data centers used in HPC environments. Low latency. Best suited for HPC, large simulations, and large-scale data analysis.
What is RoCE v2?
RDMA over converged network. Protocol that enables high performance, low latency data transfers by allowing RDMA over standard ethernet networks.
What is SPDK?
Storage performance development kit. Open source toolkit that allows direct, optimized access to storage devices through user space libraries and tools.
What is IOPS?
Input/output operations per second. Measures the number of read/write operations per second.
What is a protocol?
Set of rules that defines how data is exchanged between devices or systems.
What is FCoE?
Fibre channel over ethernet. Protocol that enables fibre channel SAN traffic to be transmitted over ethernet networks.
What is IPSec?
Internet protocol security. Suite of protocols used to secure IP communications by encrypting and authenticating data packets sent over a network.
What is JBOF?
Just a bunch of flash. A storage setup where multiple SSDs are grouped together in a single enclosure but managed independently. Flexible, cost effective way to expand storage capacity without combining them into a RAID setup.
What is RAID?
Redundant array of independent disks. Storage setup that combines multiple physical disks into a single unit for enhanced performance and redundancy. More secure and reliable, but more complex than JBOF.
What is SMB?
Server message block. Network file sharing protocol used to provide shared access to files, printers, and other resources on a remote server as if they were on a local machine.
RDMA vs RoCE?
RDMA works over various network types like ethernet, Infiniband, and Fibre Channel. RoCE is limited to ethernet.
