Overview ----- libzbc is a simple library providing functions for manipulating disks supporting the Zoned Block Command (ZBC) and Zoned-device ATA command set (ZAC) disks. libzbc implemention is compliant with the latest drafts of the ZBC and ZAC standards defined by INCITS technical committee T10 and T13 (respectively).

libzbc is a user library that provides functions for manipulating ZBC and ZAC disks. The command implementation of libzbc is compliant with the latest published versions of the ZBC and ZAC standards as defined by INCITS technical committees T10 (for ZBC) and T13 (for ZAC).

May 28, 2015 · Asymmetric dimethylarginine (ADMA) inhibits the production of nitric oxide, a key regulator of the vascular tone, and may be important in the development of cardiovascular disease (CVD).

Jun 14, 2019 · Zoned Block Device technologies were introduced with the goal of moving us towards efficient data management in large-scale infrastructure deployments. In this blog I’ll walk you through: • What are Zoned Storage Devices and why this technology is being adopted. • SMR HDDs and Zoned Namespaces SSDs.

The most common form of zoned storage today uses the SCSI Zoned Block Commands (ZBC) and Zoned ATA Commands (ZAC) interfaces with Shingled Magnetic Recording (SMR) hard-disks. ZBC and ZAC enable a zoned block storage model; SMR technology enables continued areal density growth that makes it possible to meet expanding data needs, and SMR ...

Apr 20, 2015 · The industry is in the final stages of the standardization process for SMR with ZBC (Zoned Block Commands) being the standard for SAS and ZAC (Zoned ATA Commands) being the standard for SATA. These standards define a Zoned Block Device in which the LBA space is divided into independent Zones.

The zoned block device (ZBD) interface that supports SCSI ZBC and ATA ZAC disks was added to the Linux® kernel in version 4.10. Zoned Namespace (ZNS) devices are supported from kernel version 5.9 (inclusive). All Linux kernel versions higher than 5.9 support zoned storage devices.

zbd is used to manipulate zones of a zoned block device. Zoned block devies are block devices that support the SCSI Zoned Block Commands (ZBC), ATA Zoned-device ATA Commands (ZAC) or NVMe Zoned NameSpace commands (ZNS). The zones to operate on can be specified using the offset and length options.
