New PCIe Gen4 NVMe storages for VMware cloud clients
The NVMe communications protocol, developed specifically for all-flash storage, provides faster performance and higher command density than previous protocols.
The NVMe communication protocol, developed specifically for all-flash storage, provides faster performance and higher command density than previous protocols. NVMe is designed for business processes that require top performance, such as real-time data analytics, web-based trading platforms, and other latency-sensitive workflows. With such highly latency-sensitive workflows, NVMe technology immediately benefits from adoption.
NVMe vs. serial-attached SCSI (SAS)
NVMe aims to reduce software congestion between applications and storage on all-flash systems.
Flash-based storage systems typically use SAS (serial-attached SCSI) links from their controllers to communicate with flash. SAS relies on the outdated SCSI protocol, which was originally developed for slower hard disks. SAS can be used to communicate with flash, but it is not ideal for getting the most out of flash. The interface speed of one SAS disk is 12Gb/s.
NVMe technology is designed to take better advantage of the microsecond latency provided by all-flash arrays and to overcome the bottleneck of the SCSI protocol. The increase in data transfer rate, unlike the SCSI protocol, requires the NVM's ability to use parallel low-latency data to speed up performance on all-flash arrays. The speed of the NVME Gen4 disk is 64Gb/s. Thanks to its ability to read thousands of parallel command queues, NVMe technology provides IOPS in millions.
With the transition to the HPE Synegry platform, our Fiber Channel storage network will also be renewed. The existing 16Gb Brocade switches will be replaced by the new generation Brocade 32/64Gb models.
New PCIe Gen4 NVMe storages in use
In January 2022, WaveCom invested in the next generation of data storage for the VMware cloud service platform in the Endla data center. The existing SAS SSD storages will be replaced by the fourth generation PCIe NVMe SSD storages. In the next month, the workflows of existing customers will be automatically transferred to the next generation of data storages. The transition takes place in real time without interruptions and is not visible to customers. Changes in technology will not change prices.
