IOMEGA STORAGE PROVISIONING AND RAID MIGRATION CONFIGURATION GUIDE

INTRODUCTION

The Iomega ® StorCenter ™ px12-350r network storage array offers versatile storage provisioning, advanced
protocol capabilities, expandability and affordability in an easy-to-use product ideal for small business,
workgroups and departments. Based on enterprise-class EMC ® storage technology, the StorCenter px12-350r
provides quad gigabit Ethernet connections, direct or network attach, easy file sharing, iSCSI block access,
multiple RAID configurations for optimized data protection, Storage Pools for application flexibility and
expandability to match your budget. Business users will appreciate the robust data protection features such as
UPS support, print serving, Rsync device-to-device replication, and user replaceable hot swap fans, power supplies,
and drives for business continuity and disaster recovery. The easy-to-use interface, Active Directory support, and
remote access provide no-hassle management. The StorCenter px12-350r supports PC, Mac ® , Linux ® and UNIX
clients and is VMware ® certified for NFS and iSCSI and Microsoft Windows Server 2008 R2 (Hyper-V) certified
for iSCSI.
The Iomega px12-350r allows flexible storage provisioning to offer users configuration options based on data
protection, storage utilization, and performance considerations, as well as application requirements. Disks can
be grouped into Storage Pools with or without a RAID protection level. The supported RAID data protection
types include 0, 1, 10, 5, and 6.
An existing Storage Pool with certain RAID protection types can be migrated by adding more disks while data is
online. Moreover, a Storage Pool with certain RAID types can be migrated to some other RAID types while data is
online. During the migration, the RAID group will be reconstructed but data will be continuously available,
although I/O to the Storage Pool could be significantly slowed down during the reconstruction.
This document describes the supported RAID types and storage provisioning options available on an Iomega
px12-350r, and the RAID migration paths that are permitted. The paper includes detailed instructions to help
users provision storage and plan for RAID migration.

AUDIENCE

Information contained in this white paper is intended for Iomega customers, partners, and service personnel
involved in provisioning storage on an Iomega StorCenter px12-350r network storage array.

TERMINOLOGY

RAID: Redundant Array of Independent Disks. RAID is a technology that allows high levels of storage reliability
from low-cost and less reliable disks via the technique of arranging the disks into arrays for redundancy.
JBOD: Just a Bunch Of Disks. In this mode, all disks are addressed independently with no collective properties
and the disks are concatenated to be presented as a single logical disk.
