Linux Drivers Overview

In a direct-attached configuration, the Linux driver enables the host (a Linux
machine) to access block storage on a Memory Array.
The Linux driver (
vtms-linux-driver
if the Memory Array is to be directly attached to a Linux host. If the Memory
Array is to be directly attached to a Windows host, see
135.
Understanding Linux Driver Types
Linux drivers may be implemented as one of three different device types:
character devices, block devices, or SCSI devices. The Memory Array system
supports only one device type at a time.
The Linux driver accesses the system as any of the following device types:
Character
Block
SCSI
In general, a Linux driver provides block device access to the Memory Array
enabling the host to create and mount block storage.
This chapter describes the steps required to install and configure Linux drivers
as block devices only. If you plan to use the Linux driver to enable character or
SCSI connections, contact HP Customer Support.
Installation and Configuration Overview
The Linux driver enables a direct-attached connection between a Memory Array
and a Linux host machine.
During Phase 3 of the Memory Array deployment, you may choose to configure
the system for block storage or direct-attached storage. If you choose direct-
attached configuration, you must install the appropriate device driver (Linux or
Windows) and the Violin Utilities on the host machine.
