IOPS
Input/Output Operations Per Second. Measure of how many read/write operations a system can perform per second.
Latency
The time delay between request and response, critical in HPC/AI workloads.
Lustre
Open-source parallel file system widely used in HPC.
Metadata
VDURA’s advanced protection using layered EC for up to 12 nines durability.
Multipath (Non-Parallel)
Storage where data flows through compute/controller nodes. Strong reads, but weaker writes.
NFS (Network File System)
Legacy file-sharing protocol, not parallel, limited in performance.
NVMe Non-Volatile Memory Express
High-speed protocol for SSD data transfer. Non-Volatile Memory means the storage retains data even when power is off (like flash storage in SSDs). Express refers to the fact that NVMe uses the high-speed PCIe (Peripheral Component Interconnect Express) interface to connect storage directly to the CPU. Why it matters: NVMe delivers much lower latency, higher […]
OSD (Object Storage Device)
Component that manages data in object-based systems.
PanFS
VDURA’s underlying file system technology, originally developed at Panasas.
POSIX-Compliant Interface
POSIX (Portable Operating System Interface) Ensures compatibility across different operating systems. A family of IEEE standards that ensure compatibility across operating systems (Unix/Linux/macOS, etc.). A POSIX-compliant interface lets applications written for one compliant system run on another without modification.
