What makes out-of-band storage virtualization different from in-band?

The in-band virtualization engine manages the disparate physical storage devices in the downstream SAN and presents a coherent image of metadata to the server. The out-of-band architecture avoids in-band issues by placing metadata control outside the data transport path.

What is inband and out-of-band?

In-band means sending commands in an operating system through a standard NVMe driver and commands, while out-of-band means outside of the operating system knowledge, most commonly done with a host BMC through the SMBUS protocol, but now can be done over PCIe vendor defined messages as well.

What are the three types of storage virtualization?

The three most common are host, network and array. Each serves a different storage virtualization use case.

What are the major types of storage virtualization?

Types of Storage Virtualization

  • Block Virtualization.
  • File Virtualization.
  • Host-Based Virtualization Approach.
  • Array-Based Virtualization Approach.
  • Network-Based Virtualization Approach.
  • In-Band Approach (Symmetric)
  • Out-Band Approach (Asymmetric)

Is SSH in-band or out-of-band?

In–band management is used to manage devices through telnet/SSH, using the network itself as a media. Out-of-band management uses terminal server that is connected to a management port of each controlled device.

What is an example of storage virtualization?

The simplest examples of storage virtualization object are LUN’s (Logical unit number), Logical volume (LV), RAID groups, etc.

Where is storage virtualization used?

Storage virtualization is a technique to abstract information about all of the storage hardware resources on storage area networks (SANs). This can be used to integrate hardware resources from different networks and data centers into one logical view.

What are the two types of storage virtualization?

Here is an overview of the types of storage virtualization implemented by organizations.

  • Host-based storage virtualization.
  • Array-based storage virtualization.
  • OS-level storage virtualization.
  • File-system virtualization.
  • Fibre Channel storage virtualization.

Is telnet in-band or out-of-band?

What is the meaning of out-of-band?

Out-of-band is activity outside a defined telecommunications frequency band, or, metaphorically, outside some other kind of activity.

How does out-of-band work?

Out-of-band (OOB) management is a method of remotely controlling and managing critical IT assets and network equipment using a secure connection through a secondary interface that is physically separate from the primary network connection. This enables administrators to gain control even during infrastructure faults.
