Exam #HP0-830: Implementing SANworks Solutions
The #HP0-830 Exam, Implementing SANworks Solutions, is a core or elective requirement for one Accredited Systems Engineer (ASE) specialty and two Master ASE specialties—namely, ASE for StorageWorks and the Master ASE for SAN Architect and for High Availability and Clustering.
This exam is designed to identify individuals who can design, install, support and troubleshoot storage area networking applications built around HP’s SANworks applications or who can support sales specialists either during presales or actual sales activity to explain and explore SANworks’ features, benefits and capabilities.
To be more specific, the general topic areas that this exam addresses include:
- HP SANworks Virtual Replicator: The part of SANworks that permits physical storage to be pooled and virtual disks to be defined and allocated as needed. VR also manages instant copies of virtual drives.
- HP SANworks Management Appliance: Provides centralized management and monitoring for SAN elements, including switches and storage devices. This appliance is a hardware device that connects to a SAN fabric or storage network and does not require a host computer.
- HP SANworks Storage Resource Manager: A Web-based tool to monitor, report on and generate alerts related to SANworks. It’s designed to drive capacity planning and consumption management for storage resources. It provides usage and utilization statistics, event logs, configuration data and overall storage health data. Alerts provide warnings when thresholds are exceeded or events occur.
- HP SANworks Enterprise Volume Manager: A controller-based application for the management appliance that manages automated storage unit replication to create business continuance volumes (BCVs) and more.
- HP SANworks Secure Path: SANworks software components that work together to monitor storage unit availability and to manage data access paths, should primary paths fail and backup paths be needed.
- HP Modular Array Family: A family of storage systems designed to work with SANworks to provide complete hardware/software storage solutions.
HP Course #330 (described in the next section) covers all this material and more.
Exam Prerequisites and Background Requirements
Exam #HP0-830 also includes several prerequisites. Successful completion of numerous courses is recommended, in particular, Implementing SANworks Solutions (Course #330) and Implementing and Servicing Data Replication Manager (Course #345). HP also strongly recommends completing two self-paced Web-based training (WBT) courses:
- StorageWorks Full Line Technical WBT.
- SANworks and Solutions WBT.
Candidates should be familiar with HP storage solutions on one or more of the following: Windows, NetWare, OpenVMS or UNIX platforms. For background, candidates must be familiar with Fibre Channel concepts, such as arbitrated loops, switched fabrics and Fibre Channel hardware components, and with Windows-based servers so they can comfortably navigate around and use Windows-based system management consoles and utilities.
HP also recommends reading the following online documentation to prepare for this exam:
- Data replication manager documentation: h18000.www1.hp.com/products/sanworks/drm/documentation.html
- Enterprise volume manager documentation:h18004.www1.hp.com/products/sanworks/evm/documentation.html
- Virtual replicator documentation: h18004.www1.hp.com/products/sanworks/vr/documentation.html
The #HP0-830 exam includes 62 questions. Question types likely to appear include multiple-choice, drag-and-drop and point-and-click. Candidates may take up to 75 minutes to complete this exam, for which the passing score is 66 percent (or 41 out of 62 items). Sign up for this exam at a Prometric testing center online at www.2test.com. Once the exam is over, candidates may take up to 15 more minutes to comment about the exam and to complete a follow-up survey. With the 15-minute warm-up that precedes the exam, this explains why the exam occupies a 105-minute time slot.
The #HP0-830 exam is broken into 10 modules, each of which addresses a specific aspect of understanding, designing, planning, using, maintaining and troubleshooting solutions built around SANworks:
- Application Suite: Covers topics relevant to loss of service, including issues to consider during downtime, distinctions between disaster recovery and disaster tolerance, principles behind a point-in-time copy and definitions for snapshot and clone. Also covers how SANworks applications support disaster recovery, disaster tolerance and SAN management.
- Virtual Replicator (VR): Covers using VR to manage storage, including storage units, storage pools and virtual disks, as well as how to use SANworks to create and manage such things. Also covers the business value of snapshots (and how to create and manage VR snapshots), online volume growth (and how it’s implemented in Windows 2000), plus VR’s support for clusters, SNMP, System Monitor and Diskeeper. Explores the relationship between VR and other SANworks applications.
- Enterprise Volume Manager (EVM) Concepts: Covers the features, benefits, replication methods, EVM network components (storage subsystem, EVM server, EVM client), steps required to create EVM jobs and rules to design and run EVM jobs. Also covers distinctions between controller- and host-based clone and snapshot operations.
- EVM Planning and Installation: Covers where EVM server and agent software can run, configuration limitations of EVM networks and applications and software that EVM supports. Also includes scenario analysis to identify when consolidated EVM and backup servers or clustered EVM configurations make sense.
- Secure Path (SP): Covers function and benefits of SP, SP theory of operation, software elements involved and how they collaborate to keep paths available. Also requires knowing how to configure SP for LUNs or paths, to interpret path status and distribute loads across multiple or duplicate paths.
- Data Replication Manager (DRM) Concepts: Covers DRM, how it works, its benefits and principles behind a remote copy set. Distinguish between synchronous and asynchronous replication, and explain the pros and cons of each mode. Describe how replication I/O is managed. Explain the concept of an association set and how log units and failure policies affect its behavior. Explain how DRM operates normally and explain the significance of write-history logging, mini-merge and fast-failback. Describe how failsafe mode works.
- DRM Installation and Configuration: Describe and explain steps involved in planning DRM installations. Describe how DRM supports non-remote copy set LUNs, cloning and snapshots. Explain how HSG80 RAID Array controllers are configured to work with DRM. Analyze scenarios to distinguish between DRM standard and firewall topologies. Itemize and explain proper DRM power-up and power-down, planned and unplanned failures and failback procedures.
- Management Appliance (MA): Describe and explain the MA and its components: Open SAN Manager, SANworks Resource Monitor, Storage Allocation Reporter and HSG Element Manager. Itemize hardware and software installation for the MA. Itemize monitoring, notification methods and their benefits for the SANworks Resource Monitor, benefits for Storage Allocation Reporter and components and capabilities for HSG Element Manager.
