Issci Storage 

Synology Cloud Station Issci Storage the now massive data has been generated every day that need to be stored safely and managed economically so that they can be available to users when needed. Thus various storage systems emerged such as Network Attached Storage (NAS), Internet Small Computer System Interfaces (iSCSI), etc.

Among them, iSCSI storage is the preferred new technology that provides high speed, low cost and long distance. storage solution. Here will introduce what iSCSI storage is and provide tips for planning iSCSI SAN. iSCSI is a storage area network protocol that defines how data is transferred between the host system and storage device. 

So iSCSI storage is also known as iSCSI SAN storage, which is a cost-effective alternative to traditional SAN Fiber Channel (FC). Unlike FC SAN that requires special hardware (FC HBA, FC switch, etc.), iSCSI SAN storage can be built on existing network infrastructure (fiber switches, routers, etc.), Instead of requiring us to buy additional hardware. Furthermore, iSCSI is based on block transfer standards, which are faster and more efficient. 

To understand how iSCSI storage works, we should know about iSCSI initiators and iSCSI targets in Synology Cloud Station Issci Storage. The iSCSI initiator is a client component on the host system that uses storage. This is responsible for initiating requests and receiving responses from iSCSI targets. The iSCSI target is on a storage device that provides storage, which listens and responds to commands from the iSCSI initiator. 

As shown below, iSCSI storage works by transporting block level data between an iSCSI initiator and an iSCSI target over a TCP / IP network. Except for the advantages mentioned above such as cost savings and high performance, iSCSI storage also offers benefits. Because iSCSI runs on Gigabit Ethernet network components (Gigabit Ethernet switches, routers, etc.), it not only makes it cheaper to adopt but also simplifies the network storage environment. 

Synology Cloud Station Issci Storage Overview

IT staff do not need additional skills training to handle iSCSI storage. Anyone familiar with TCP / IP technology can easily install and manage iSCSI SANs iSCSI storage is based on TCP / IP which is universal and non-proprietary technology, therefore various branded network storage devices at iSCSI SAN can work smoothly together same. 

With iSCSI, the SCSI storage command that issues a virtual machine to its virtual disk is converted into a TCP / IP protocol packet and sent to a remote device, or target, where the virtual disk is located. For virtual machines, the device appears as a locally installed SCSI drive. To access remote targets, ESXi hosts use the iSCSI initiator.

The initiator transports SCSI requests and responses between ESXi and the target storage device on the IP network. ISCSI adapter software. VMware code is built into VMkernel. Allows ESXi hosts to connect to iSCSI storage devices through standard network adapters. The software initiator handles iSCSI processing when communicating with network adapters. ISCSI hardware adapter. Offload in all iSCSI and network processing from the host. 

ISCSI adapter hardware is broken down into two types. ISCSI dependent hardware adapter. Take advantage of the VMware iSCSI management and configuration interface. Independent hardware iSCSI adapter. Make use of the iSCSI configuration and management interface itself. See vSphere Storage documentation for details about setup and failover scenarios. Configure the iSCSI initiator for hosts to access and display iSCSI storage devices.

ISCSI storage describes hosts that use various types of iSCSI initiators. The host on the left uses an independent iSCSI hardware adapter to connect to the iSCSI storage system. The host on the right uses iSCSI software. ISCSI dependent hardware can be implemented in different ways and not displayed. An iSCSI storage device from a storage system becomes available to the host. Access storage devices and create VMFS datastores for storage needs in Synology Cloud Station Issci Storage.
