 Overview  Product Description  Key Features  Clear Customer Benefits  Storage Features  Supported Host Operating Systems

Overview

 Supported Topologies  Concepts and Terms

Your Hitachi Simple Modular Storage 100 is a cost-effective, easily deployable, and fully integrated iSCSI storage solution that allows servers to connect to storage networking using Internet SCSI (iSCSI).

iSCSI is a standard for linking data storage devices over a network and transferring data by carrying SCSI commands over IP networks. On your Hitachi Simple Modular Storage 100, iSCSI disks reside on an expandable RAID-protected volume, but appear to a client machine as a local SCSI drive. Connectivity to the iSCSI disk is established using a software package or PCI card known as an iSCSI initiator, which must be installed on a client machine. The initiator recognizes your Hitachi Simple Modular Storage 100 as a “target portal” and an iSCSI disk as a “target.”

Introduction 1–1

Hitachi Simple Modular Storage 100 User’s Guide

Hitachi Data Systems has qualified a number of iSCSI initiators, network interface cards (NICs), and other devices to interoperate with your Hitachi Simple Modular Storage 100.

Features

• ShadowImage™ In-system Replication software

• Hitachi Copy-on-Write Snapshot software

From accidental file deletions to natural disasters, all kinds of data calamities threaten business operations and escalate the demands for better business practices. The challenge facing most companies is how to minimize the lost revenue and operating expenses these disasters cause. No matter what your company does or what size it is, business continuity matters to you. Y our ability to recove r data and resume operations depend completely on what you do before the disaster.

Introduction 1–3

Hitachi Simple Modular Storage 100 User’s Guide

Data backups offer critically important benefits, as long as backups are done correctly and consistently. ShadowImage In-system Replication software offers nondisruptive, high-speed data backup operations on a copy of up-to-date production data, while critical applications run unaffected and businesses remain online.

Traditional downtime recovery processes can be labor-intensive and span several hours, during which production data is unavailable. Copy-on-Write Snapshot software rapidly creates point-in-time copies of any data volume within your Hitachi Simple Modular Storage 100 without impacting application service or performance levels. Because snapshots store only the changed data blocks, the storage capacity required for each copy is substantially smaller than the source volume, providing significant savings over full cloning methods. The Copy-on- Write Snapshot copies are fully read/write compatible, simplifying rapid data restores, data mining and warehousing, and nondisruptive backup and maintenance procedures.

NOTE: ShadowImage In-system Replication software and Copy-on-Write Snapshot software are available only for Hitachi Simple Modular Storage 100s equipped with dual controllers.

LUN Management

Security

Feature

•LUN Manager A Logical Unit Number (or LUN) refers to either an entire physical disk, or a

subset of a larger physical disk or disk volume. LUNs represent the “virtualization layer” between the physical disk/volume and applications. A LUN can be used to present a smaller view of the total amount of disk storage available to a server. For example if you partition a drive into small pieces for an application or to accommodate disk limitations of your server’s operating system, each segment would share a common SCSI target ID, with each partition having a unique LUN.

LUN Manager streamlines the processes associated with adding, configuring, modifying, deleting, and reassigning LUNs to specific paths without having to reboot your array. LUN Manager also lets you assign multiple paths to a single LUN to support alternative path failover, path load balancing, and clustered systems.

Feature

• Password Protection Your Hitachi Simple Modular Storage 100 offers several data-protection

features to protect your critical data assets. Password Protection lets you restrict access to your Hitachi Simple Modular Storage 100 to one registered user at a time.

Supported Topologies

Y our Hitachi Simple Modular Storage 100 is designed to provide disk storage for use by your host servers. At its front end, your Hitachi Simple Modular Storage 100 uses the iSCSI protocol over Ethernet to connect to iSCSI HBAs or NICs installed in your server. This connection can be a direct, point-topoint connection or a switched configuration through an IP storage switch (also known as a “fabric”).

At its back end, your Hitachi Simple Modular Storage 100 contains six, eight, or 12 internal SATA or SAS drives. The drives are preconfigured for RAID 6 and are not intended to be removed from the array . Two spare drive slots are provided for adding capacity, for a total of 12 drives and 9 TB of storage.

Hitachi Simple Modular Storage 100 User’s Guide

Concepts and Terms

This section describes key concepts and terms you will find helpful when using your Hitachi Simple Modular Storage 100. For additional assistance, a

Glossary at the back of this guide defines the technical terms in this guide.

RAID 6

Drives in your Hitachi Simple Modular Storage 100 are preconfigured for RAID 6. RAID 6 is an extension of the RAID 5 arra y, with a second independent distributed parity scheme. Data and parity are striped on a block level across multiple array members, and a second set of parity is calculated and written across all drives. In this way, RAID 6 delivers enhanced data protection compared with single-parity RAID systems by allowing for two simultaneous drive failures without downtime or data loss.

Y our Hitachi Simple Modular Storage 100 supports RAID 6 in 6-, 8-, or 12drive configurations:

• For arrays with six drives, four drives are used for data and two are used for parity.

• For arrays with eight drives, six drives are used for data and two are used for parity.

• For arrays with 12 drives, 9 drives are used for data, two are used for parity, and one acts as a spare in case one of the other drives fails.

iSCSI

Y our Hitachi Simple Modular Storage 100 is an iSCSI storage device. iSCSI (pronounced “eye skuzzy”) is an IP-based protocol that leverages the low cost and familiarity of Ethernet and IP networking.

iSCSI links data storage devices over standard Ethernet-based TCP/IP networks using small computer system interface (SCSI) commands. Because iSCSI uses the standard Ethernet infrastructure to provide access to storage “targets,” it is compatible with, and can connect directly to, standard Gigabit Ethernet switches and IP routers. In this way, iSCSI enables low-cost storage access through the mature and predominant Ethernet infrastructure.

iSCSI Initiators and Targets

iSCSI defines a SCSI encapsulation protocol across a TCP/IP connection. As with SCSI, there are two types of components in an iSCSI system: initiators and targets.

An iSCSI initiator is a hardware device — such as an iSCSI host bus adapter (HBA) or TCP/IP offload engine (TOE) — and/or software installed in a server. The iSCSI initiator is the source of iSCSI commands that are sent over the network to the target. As such, it is responsible for:

• Originating iSCSI requests for target discovery and target connection.

• Creating the iSCSI packets.

Introduction 1–7

Hitachi Simple Modular Storage 100 User’s Guide

LUNs

• Handling transmission of the packets and corresponding responses using TCP/IP.

An iSCSI target is a device that receives iSCSI requests originating from an iSCSI initiator. Typically, the target is a drive contained in a storage device, such as your Hitachi Simple Modular Storage 100.

The following steps describe the sequence followed by the iSCSI initiator and target when establishing a “session.”

1. The iSCSI initiator starts a TCP session with a target and tries to log in by sending a list of log-in parameters.

2. The initiator and target may insist on authenticating each other with one of several authentication methods (described next), depending on the system's configuration.

3. After passing the authentication stage, the initiator and target negotiate operating parameters, after which SCSI commands and data can pass between them.

Y our Hitachi Simple Modular Storage 100 includes several drives, with each drive including many gigabytes of storage. To effectively enable access to this storage, it is organized into smaller portions called logical units or volumes that can be allocated to different resources that want to access the storage.

CHAP

Each volume itself consists of a numeric address, thereby permitting the storage on your Hitachi Simple Modular Storage 100 to appear as many smaller storage units to the host computers accessing it, enabling more efficient operation. To the server, a volume appears to be a single virtual “disk”.

LUNs can be assigned to hosts, so that a particular volume can be accessed only by designated hosts that have “permission” to access that portion of the storage. This provides enhanced security as the software controlling access to the storage system will only permit access by certain previously defined hosts. While it is somewhat arbitrary how many hosts are permitted to access a given volume, conventionally only one host usually has access rights to a given volume at a given time. As a result, data on t he volume is protected against access by hosts or servers other than those previously designated, thereby enhancing the security of the data.

The Challenge Handshake Authenti catio n Protocol (CHAP) is a security mechanism that one entity uses to verify the identity of another entity, without revealing a secret password that is shared by the two entities. In this way, CHAP prevents an unauthorized system from using an authorized system's iSCSI name to access storage.

1–8 Introduction

Hitachi Simple Modular Storage 100 User’s Guide

CHAP involves configuring a secret that both your Hitachi Simple Modular Storage 100 and the host server must know . You enable and configure CHAP using Storage Navigator Modular 2. CHAP is not enabled by default, but it is strongly recommended. The Storage Navigator Modular 2 online help describes how to enable and configure CHAP.

The following sequence describes how CHAP works when it is configured and enabled on your Hitachi Simple Modular Storage 100.

1. During negotiations between the iSCSI initiator and target, the initiator sends a “challenge” message to the target.

2. The target responds with a calculated value.

3. The initiator compares the response against its own calculation of the value. If the values match, the initiator acknowledges the authentication; otherwise, it terminates the connection.

At random intervals, the initiator sends a new challenge to the target and repeats steps 1 through 3 to ensure that it is communicating with the appropriate peer.

Cache

A temporary , high-speed stor age mechanism. It is a reserved section of main memory or an independent high-speed storage device. Two types of caching are found in computers: memory caching and disk caching. Memory caches are built into the architecture of microprocessors and often computers have external cache memory. Disk caching works like memory caching; however, it uses slower, conventional main memory that on some devices is called a memory buffer.

Capacity

The amount of information (usually expressed in megabytes) that can be stored on a disk drive. It is the measure of the potential contents of a device; the volume it can contain or hold. In communications, capacity refers to the maximum possible data transfer rate of a communications channel under ideal conditions.

A multi-featured scalable storage management application that is used to configure and manage the storage functions of Hitachi arrays. Also referred to as “Navigator 2".

Subnet

In computer networks, a subnet or subnetwork is a range of logical addresses within the address space that is assigned to an organization. Subnetting is a hierarchical partitioning of the network address space of an organization (and of the network nodes of an autonomous system) into several subnets. Routers constitute borders between subnets. Communication to and from a subnet is mediated by one specific port of one specific router, at least momentarily. SNIA.

Switch

A network infrastructure component to which multiple nodes attach. Unlike hubs, switches typically have internal bandwidth that is a multiple of link bandwidth, and the ability to rapidly switch node connections from one to another. A typical switch can accommodate several simultaneous full link bandwidth transmissions between different pairs of nodes. SNIA.

Target

Devices that receive iSCSI requests that originate from an iSCSI initiator.

TOE

A dedicated chip or adapter that handles much of the TCP/IP processing directly in hardware. TCP/IP transmission is inherently a CPU-intensive operation. Therefore, using dedicated hardware that can operate in parallel with the main processor allows for superior system performance. Although all iSCSI HBAs have a TOE, a generic TOE only implements TCP/IP, while an iSCSI HBA implements the iSCSI protocol in addition to TCP/IP.
