- Storage Basics: SCSI Part I - Enterprise Storage Forum
In this article, the next in our series 'Storage Basics', we are going to look at the Small Computer Systems Interface (SCSI) SCSI is a complex subject,
- What Is iSCSI? Definition, Performance Limitations
The SCSI commands are sent to a SCSI controller, and the controller diverts those SCSI commands to the SCSI storage device The iSCSI protocol is bi-directional and can also return data in response to the original request
- Storage Basics: Understanding SANs - Enterprise Storage Forum
The SCSI bus, parallel in nature, can only support a single communication at a time, so subsequent sessions must wait their turn SAS, or Serial Attached SCSI, does away with this limitation by automatically switching back and forth
- Storage Basics: iSCSI - Enterprise Storage Forum
SCSI protocols are standards that exist to define how data is transferred from the data initiator (server) to the storage target (disk array) Until iSCSI, which stands for the Internet Small Computer Systems Interface, came along, it was not possible to transfer SCSI data where the distance between the storage initiator and storage target was
- T10 Accepts Proposal on Serial Attached SCSI Standard
The proposed Serial Attached SCSI standard is a device level interface which builds on the foundation of the SCSI protocol while bringing the advantages of a serial point-to-point interconnect The serial interface will enable dense storage solutions as well as the migration to smaller form factors
- NAND, DRAM, SAS SCSI and SATA AHCI: Not Dead, Yet
But the reality is that SCSI-based SAS and AHCI-based SATA will be around for several years—although their roles may change They will be necessary for compatibility with existing servers, storage, I O devices, hardware, software, systems and deployments, as well as for near-term low-cost high-capacity commodity interfaces
- What Is Fibre Channel? | Enterprise Storage Forum
Fibre Channel vs SCSI SCSI is a standard interface used for computer-to-storage connectivity, but has limits related to local area network (LAN) storage performance and does not excel at supporting multiple host-to-storage device connections SCSI is best for point-to-point connections or direct attached storage (DAS) interfacing
- NVMe over Fibre Channel: What You Need to Know
How Does NVMe over Fibre Channel Work? Historically, SANs used three protocols to transfer data: internet small computer systems interface (iSCSI), serial attached SCSI (SAS), and Fibre Channel Protocol (FCP) But the shortcomings of these protocols became apparent when they proved unable to support the full potential of high speed solid state storage The solution was NVMe, a new storage
