Preface

StorageCare Guardian

StorageCare Guardian 0

StorageCare Guardian is a remote monitoring and diagnostic solution that

enables Quantum to proactively monitor the products, use diagnostic data to predict possible failures, and determine whether or not the problem involves a Quantum product or other critical component in the environment.

health of Quantum

Benefits

More Reliable Backups

Faster Resolution Time

StorageCare Guardian gives the customer added assurance that Quantum

will make sure its products are running optimally to ensure maximum operational efficiency. Deploying this solution is easy and enables customers to minimize the costs associated with system downtime and service issues should a problem arise.

Through continuous 24x7x365 monitoring, StorageCare Guardian proactively checks Quantum systems for common errors and alerts the customer when a Quantum product is underperforming. By proactively identifying red flags, the risk of failed backups and machine downtime can be mitigated.

When the system is down, StorageCare Guardian provides the necessary diagnostics data that enables Quantum to identify the root cause and expedite the problem resolution process. Problems that used to take days to fix can now be fixed in minutes. When problems require onsite support, field engineers will have better information along with the right parts necessary to fix the problem.

StorageCare Guardian allows Quantum to

• Monitor diagnostic data related to Quantum products

• Receive alarms that notify Quantum of issues

• Run diagnostic utilities to more quickly determine the root cause of i

ssues

Preface

StorageCare Guardian

• Initiate remote connection to remote management interface to get more in-depth information about the health of your Quantum product.

• Distribute software/firmware upgrades - this will be available as a future enhancement

Product Features 0

• Continuous Monitoring - Proactive 7x24x365 monitoring of Quantum products enabling Quantum Support to be alerted on events such as errors or marginal conditions that are defined by the user.

• Root Cause Diagnosis - Allows Quantum to quickly isolate and identify the root cause of a problem.

• Rapid Problem Resolution- Quantum can rapidly recommend and/ or implement the corrective actions needed to resolve a problem ensuring minimal impact to the IT environment.

• Quantum Remote Software Update - Distributed software update capability allows fast updates to agent software and Quantum hardware installed at customer sites

• Real-time Data Collection - Instant on-demand or scheduled diagnostic data collection from Quantum products as well as the ability to run user-defined data collection scripts from agent.

• Access Management - Customer has full control over Quantum's access rights and privileges.

• Audit Logging - Audit logs are kept for all communications to and from the agent.

How it works: 0

1 Customers can download the StorageCare Guardian agent software

from

http://www.quantum.com/guardiandownload.

2 Customer installs the StorageCare Guardian agent on any Windows

2000/2003/XP or Solaris 8/9 server located at the customer’s site.

3 The StorageCare Guardian agent monitors Quantum products, and

provides information and updates to the Quantum Enterprise Server that resides at Quantum Support.

Quantum Scalar 50 User’s Guide xxiii

Preface

StorageCare Guardian

4 If an error or problem is detected, Quantum queues a request to the

StorageCare Guardian agent for data collection or real-time access to

the system.

5 The StorageCare Guardian agent checks access policy settings to

determine if access is allowed.

6 If approved, the information is transferred to Quantum, or a remote

connection is initiated.

7 Quantum Support will diagnose the problem and, if necessary, send

the needed parts and/or field personnel to resolve the issue.

8 Quantum can identify if the backup problem is not associated with

the Quantum device and then direct the customer to resolve the issue with appropriate third-party vendor.

Chapter 1 Library Description

Overview

The Quantum Scalar 50 tape library (see figure 1) is an automated tape storage and retrieval device that may consist to 32 SDLT or 38 LTO tape cartridges. Cartridges are stored in two removable cartridge magazines and two fixed slots. Both SDLT and LTO tape cartridges can be installed in a single library as long as the appropriate magazines and drives are installed.

Chapter 1 Library Description

Tape Drives

Scalar 50 tape libraries are equipped with either SCSI or native Fibre Channel tape drives. SCSI buses are SCSI-2 fast/wide (8/16 bit), Ultra 3 SCSI, Ultra 160, or Ultra 320 SCSI, depending on the drives installed.

Table 1 DLT-S4 Performance Characteristics

LVD SCSI configurations have a maximum allowab meters. To determine the cable length of the bus, measure the lengths of the SCSI cables connecting each device to that bus and add those lengths together. To that total length, add 12.25 inches (31.10 cm) for the internal SCSI cable length of each SCSI tape drive.

The Scalar 50 tape library support the following tape drives:

• Quantum DLT-S4 (SCSI and Native Fibre Channel)

• Quantum Half-Height LTO-3 (SCSI

• HP LTO-3 (SCSI and Native Fibre Channel)

• HP LTO-4 (SCSI and Native Fibre Channel)

• HP Half-Height LTO-4 (SAS)

Scalar 50 library can support mixed media types, mixed (Fibre Channel and SCSI) as well as mixed form factors within the same library. Example: The Scalar 50 can contain both LTO full height drives with LTO half-height drives in the same library.

Refer to the following tables for tape Both SDLT and LTO tape drive can exist in the same library as long as the appropriate magazines are installed in the library.
