Why Buy HP Qualified Memory?
Introduction
DRAM quality and reliability are more important now than ever, mainly because of the increasing use of server virtualization. Virtualization has many benefits, but it dramatically increases the amount of memory servers need for optimal virtual machine performance. This rise in memory use has caused server manufacturers to expand the memory capacity of their systems. In the last 5 years alone, the average memory installed across all HP ProLiant server lines has grown by more than 500%—from 4 GB to well over 30 GB per server.
The growth in memory use has also caused memory manufacturers to increase the storage capacity of DRAM devices from 512 Mb to 4 Gb per chip. Today, a 4 Gb x4 DRAM chip contains more than 4 billion memory cells. Therefore, a quad-rank 32 GB DDR3 DIMM with 72 of these 4 Gb chips (including ECC) has more than 288 billion memory cells. As DRAM cells become smaller, manufacturers also lower the operating voltage to increase the memory speed and decrease power use. The shrinking chip geometry and higher memory speeds make DRAM quality critical for reliable operation.
We understand the difference memory quality makes in server uptime. This paper describes how we qualify HP memory in our extensive HP Memory Qualification (HPMQ) program and back it with the best warranty in the industry. But first, let’s address a major misconception among some customers that “all memory is the same.”
Designing and Building a Datacenter Netwwork: An Alternative Approach with OpenFlow
Executive Summary
Server virtualization and cloud computing are changing the face of enterprise
computing today. Virtualization enables more efficient use of IT resources and greater
levels of IT agility and control. Cloud extends these benefits, allowing IT organizations
to reduce their infrastructure complexity, ease staff workload, and more rapidly scale
compute resources. Together, these technologies enable organizations to better meet organizational demand and provide greater agility for the enterprise
Unfortunately, most current network technologies were not developed with the needs of virtualization and cloud computing in mind, and as a result, the network can become a bottleneck to cloud and virtualization deployments. Static topologies require manual intervention to deploy and migrate virtual machines (VMs), which adds cost and burden to IT and hinders the organization's ability to respond quickly to changes in the environment.
OpenFlow is an open source networking architecture that is supported and promoted by the Open Networking Foundation (ONF) and designed to address these shortcomings. An extension of Ethernet, OpenFlow separates the data path and control path, with all networking logic and policies handled by a separate controller. This introduces a new layer of abstraction in networking, analogous to server virtualization, and enables the network to act as a single fabric.
With OpenFlow, the network acts as one "big switch." All logic occurs in software and can be changed as application and network requirements change, allowing for instant and automatic propagation of new policies throughout the network, simplification of network management, and dynamic partitioning of the network to easily handle multitenant environments or traffic segmentation needs as one would using VLANs.
Toshiba Small Form Factor Disk Drive White Paper - The Economic Power of Lower Power Consumption without Sacrificing Capacity
You don’t have to be an advocate for combating global warming to care about how much energy the systems in your data center consume. The simple profit-and-loss economics of running your business will tell you all you need to know: When your computers use less energy, they cost less to operate which increases your company’s profits. It does not get any simpler than that.
However, the progress of technology has worked against that basic model. While today’s computers offer higher processor speeds and more memory at a lower acquisition cost than ever before, they cost much more to operate. While newer server-class computers are smaller and more powerful than previous models, the increased processing power, larger memory size, higher storage capacity, and other peripheral devices require more electricity to operate. In addition, the smaller size and greater power of recent server-lass computers have enabled IT managers to easily fulfill escalating user access demand by increasing the number of servers housed in their data centers.
The power consumption problem is not confined to applications servers. Advances in system and network design have allowed mass storage to exist within the network domain; this storage is external to the servers and PCs they service. These storage devices also rely on today’s very powerful, but energy-consuming and heat-producing processors and disk drives. The energy problem is further compounded by network gateway and firewall devices, such as routers, switches and security appliances of various types, all which contain components using newer and higher energy-consuming technologies.
Energy consumption and heat generation are not new problems for the computer industry. Processor, memory, and disk drive designers and engineers have consistently found methods to reduce the energy requirements and heat dissipation characteristics of their products, even as the computing performance and capacity points have increased. However, these energy advancements have been off-set by accelerating user demand, as well as heightened security needs and network complexity, causing dramatic increases in the demand for computer processing power and storage capacity, which in turn drives the need for more energy.

1 Direct Imaging: inherently high colour consistency
The Océ CPS800/CPS900 is based on Direct Imaging (DI) printing technology, with seven toner colours and partitive colour mixing. Direct Imaging is a digital printing process, in which the toner image is created directly, without charging, organic photoconductor, laser or LED illumination or other external means. Direct Imaging is therefore insensitive to effects like humidity and temperature, and produces inherently high colour consistency.
More knowledge about this colour technology will help users to achieve better and more accurate colour print quality, to find interesting printing applications and, in general, to understand the operation of the Océ CPS800/CPS900 colour printer.
Removing Paper Obstacles to Operational Excellence in Manufacturing
MANUFACTURING INSIGHTS OPINION
Manufacturing firms have made great strides in improving their productivity over the past 10 years. Much of the credit goes to continuous improvement methodologies such as lean and Six Sigma. These initiatives have eliminated wasteful activities, introduced greater consistency, and provided a measure of control. In fact, our research shows that companies with mature continuous improvement programs enjoy faster revenue growth and higher profitability.
However, manufacturing firms still rely on paper-based forms for processing. High levels of paper clutter, manual completion, and duplicate keypunching represent areas of waste that most firms have not addressed. This is particularly true for operational activity ó incoming material, production processes, and finished goods shipping. Some information collection has been automated, largely to support transactions relative to a company's enterprise resource planning application, but the majority of information collection is less structured and a great candidate for digital capture technologies.
The central benefit of moving to digital capture in manufacturing lies largely in removing these wasteful paper obstacles to fully realizing the potential of continuous improvement activities. Document management becomes less costly as the storage and retrieval of important reference information becomes more streamlined. And the information itself becomes more complete, accurate, and timely. An additional benefit of the technology is the shift to electronic processes, which is certainly in line with companies' efforts to be more environmentally sustainable.
Manufacturing Insights recommends that manufacturing firms look at technologies such as digital penñbased information capture and document scanning as enablers to capturing these benefits. These technologies are intuitive to use and provide a rapid return on investment. The investments integrate and complement continuous improvement activities.
Enterprise Records Management - Demand for a Comprehensive, Compliant ERM Program Is Clear...
Introduction
While records management has traditionally focused on physical assets (paper, microfilm/fiche, etc.), today’s business realities have driven a renewed focus on the management of enterprise records. Even so, as technology and services to manage electronic records are now available and maturing, the process and strategy for enterprise-level records management requires preparation, planning and an approach that includes active participation from several areas of the organization.
Many technology vendors have jumped on the “Compliance Bandwagon”—not always with success. There is no out-of-the-box ERM or compliance solution in today’s marketplace. Compliance technology, especially for archival and formal records management, is also being leveraged for litigation and discovery initiatives (suspension, hold, preservation). Further, wider adoption of enterprise content management technologies (including imaging, document management, archival, storage, workflow, etc.) is on the rise as
companies seek to implement a solid records management strategy.
The Many Challenges of Records Management
Records management spans multiple formats, with electronic gaining on paper every day. Making the transition from physical to electronic records
management is a key challenge, with many organizations lacking expertise to fully internalize and implement these changing requirements. The ability to maintain accurate records from creation through storage to final disposition adds complexity, as does integrating with legacy and other line of business (LoB) imaging, archival and document management systems.
Compliance and regulatory mandates, while some are new, offer acute challenges for organizations with high volumes of records. Staying current on regulatory changes and new requirements and keeping costs down while adhering to these requirements are crucial. Other key challenges include establishing and enforcing records creation and policies, and engaging employees on their responsibilities.
MFP Network Printing Productivity - Understanding Conflicting Network Printing Productivity Claims
What Impacts Productivity?
Q: What is the purpose of this document?
A: The purpose of this document is to discuss the elements that impact network
office printing performance and to also provide testing recommendations.
Q: Rated Speed; Vendor Claims; Consultant Test Reports — all with different results! Confusing?
A: If you look at product brochures, advertising claims, and third-party test results, you are probably confused as to why there is such a variance in productivity results for the same product.
Historically, the rated copier speed was very close to the device’s actual speed. With printing, however, there are many factors that affect a device’s performance and they often create a large gap between a device’s rated speed and it’s actual speed— especially in busy office environments.
Industry-standard rated speed can be determined by placing an original on the device platen, selecting 100 copies and pressing start. After the first page reaches the output tray, a certain number of pages will be produced in the next sixty seconds. For example, a device with a rated speed of 50 pages per minute (PPM) will produce 50 pages in the next sixty seconds after the first copy is produced. However, when printing documents, a device with a rated speed of 50 PPM may on only achieve 50% of its rated speed.
Q: What do the industry consultants say?
A: There are several independent consulting companies that perform print
productivity testing and analysis of multifunctional systems. Each company has its own test methodology, and because of this, each vendor ends up with different test results for the same product. The test results are still accurate, but may vary because each company uses a different test suite. In lieu of commenting on each company’s test suite and methodology, we will discuss the factors affecting test results that should be considered when reviewing information about a device’s performance.
Virtualized Systems as a Basis for Redundancy
Foundation for Business Continuity, Disaster Recovery, and Managed Failover
Many people seem to know they want or need to virtualize their systems, but far less seem to have a good grasp of why they should do so. Virtualization holds a great deal of promise for redundancy to support business continuity and similar needs; the big question is how much capability comes “out of the box” and how
much other work is required to have a robust solution?
This document will discuss several levels of infrastructure redundancy with a view to accomplishing maximum possible uptime based on various risk factors, and suggest several possible architectures that correspond to different levels of risk mitigation. These will range from internal factors within a given component’s design to large-scale infrastructure designs to mitigate catastrophic failure of a site. Several of these factors are not
unique to a virtualized environment and will be identified. While several different parts of the overall infrastructure will be addressed, areas such as power and Internet Service Provider (ISP) redundancy require a far more extensive investigation and this paper will only touch on the topics needing to be covered.
Types of Redundancy within Individual Components (Server and Storage)
Within a given host computer, it is recommended that you have at least two forms of redundancy, assuming there is no local storage. Local storage, that is disks or RAID arrays installed within a single server, are not available to other servers in case of system failure and are therefore not suitable. In addition, storage that is considered highly available requires some specific design features for redundancy.
- Power Supply Redundancy allows you to continue full operation in the event of a single power supply component failure, along with the ability to hot-swap a replacement power supply for the failed unit without interrupting production. Within Kodak, any of the Premium Workflow servers come with hot-swappable redundant power supplies by default. If selecting host computers from another vendor, ensure that the systems contains redundant power supplies. This also applies to any server or storage component in the system.
Overcoming Barriers to AP Automation: A Roadmap for Success
In 1999, the head of a major electronic-invoicing task force predicted that 95 percent of the Fortune 500’s U.S. paper invoices would be transformed into electronic invoices by 2002. Over 10 years later, that prediction has not been fulfilled.
Although there have been significant technological breakthroughs that can help accounts payable dramatically reduce costs and improve cycle times, most AP organizations have been slow to adopt them. Invoice automation is one example.
An annual survey of technology adoption in AP conducted by RECAP Inc. for 10 years from 1998 through 2007 found that adoption of technology takes significantly longer than it should. In follow-up discussions with selected survey participants, it was discovered that many firms repeatedly put off their key automation initiatives despite significant pressures to reduce costs and reduce AP cycle time, the time from receipt of an invoice to payment.
Typically 80 percent of the work done in accounts payable is associated with invoice processing. Over 99.9 percent of all invoices are prepared on computers, yet the vast majority of them are processed by manually keying information from a paper invoice document into an automated system to
process and pay.
Document Scanning in the Office
Advanced Recording Techniques
This white paper explores how document scanning can improve productivity, protect information, and create opportunities to lower operational costs in front office environments. It cites independent research conducted with individuals from 180 organizations representing a cross section of small, medium, and global businesses representing manufacturing, high technology, financial services, retail, health care, transportation, real estate, and professional service industries. In addition, public sector organizations representing utilities, educational institutions, State, local, and federal government agencies also participated in the research. The conclusions summarized in this white paper show that the scanning of documents will accelerate in the front office as paper documents continue to be the lifeblood of everyday work processes.
Executive Summary
Document scanning has evolved from the traditional, monolithic “back-office” production-level systems for capturing documents to the current de-centralized model where information is captured “at the point of need.” Like traditional scanning applications, these de-centralized operations focus mainly on documents whose value has been predetermined to be critical to a particular line of business. However, a new need has emerged where all types of business documents will be scanned regardless of their known value to the organization. The realization that all documents can increase in their value once digitized will drive much of the new market for document scanning. This new frontier for scanning will be focused on “front office” environments where information workers interact with customers, partners, and each other.
The need for digitizing paper documents to enhance productivity, security, compliance and data protection has extended beyond specific line-of-business applications to include every document type, at every level of the organization, across government and industry; in small, medium, and large enterprises.
This white paper is divided into seven sections:
- Section one provides an introduction to the paper problems facing today’s business professional and an overview of the research conducted in support of this document
- Sections two through six analyze research findings related to paper filing, storage, and retrieval, the emergence of Adobe PDF as the ideal container for scanned images, security and disaster recovery, and information distribution.
- Section seven provides a summary and conclusion.
