A virtual storage area network (virtual SAN, VSAN or vSAN) is a logical representation of a physical storage area network (SAN). A VSAN abstracts the storage-related operations from the physical storage layer, and provides shared storage access to the applications and virtual machines by combining the servers' local storage over a network into a single or multiple storage pools.
VMFS-L is the underlying file system for VSAN-1.0. Leaf level VSAN objects reside directly on VMFS-L volumes that are composed from server side direct attached storage (DAS). File system format is optimized for DAS. Optimization include aggressive caching with for the DAS use case, a stripped lock down lock manager and faster formats.
SPECsfs2008 is the latest version of the Standard Performance Evaluation Corporation benchmark suite measuring file server throughput and response time, providing a standardized method for comparing performance across different vendor platforms. EMC DSSD D5 Flash Up to [neutrality is disputed] 10 million IOPS [31] [non-primary source needed]
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
The performance of complex applications on HPC systems can depend on a variety of independent performance attributes of the hardware. The HPC Challenge Benchmark is an effort to improve visibility into this multidimensional space by combining the measurement of several of these attributes into a single program.
Release 4.3 of the SVC held the Storage Performance Council (SPC) world record for SPC-1 performance benchmarks, returning nearly 275K (274,997.58) IOPS. There was no faster storage subsystem benchmarked by the SPC at that time (October 2008). [2] The SPC-2 benchmark also returned a world leading measurement of over 7 GB/s throughput.
In virtualization, input/output virtualization (I/O virtualization) is a methodology to simplify management, lower costs and improve performance of servers in enterprise environments. I/O virtualization environments are created by abstracting the upper layer protocols from the physical connections .
Temporal isolation or performance isolation among virtual machine (VMs) refers to the capability of isolating the temporal behavior (or limiting the temporal interferences) of multiple VMs among each other, despite them running on the same physical host and sharing a set of physical resources such as processors, memory, and disks.
