Direct Attached Storage DAS Whitepapers and Ebooks

DAS has always been the backbone of server storage, and the initial file sharing storage environment developed by the industry. A DAS configuration consists of ‘N’ drives connected inside your server, typically to a SCSI controller. In fact, the hard drive inside your PC or laptop is DAS. DAS is reliable, inexpensive, high performing, and the simplest form of storage. On a server level, a server with sufficient DAS storage can run a network sharing protocol (NFS or CIFS) and a DAS based server can also be a file server. On the downside, a DAS storage tends to create storage silos, where it can become common to have uneven allocations of storage across servers.

  • Outthink the Threat. How data-stealing malware is thwarting enterprise security
    In the last few years, the Internet security environment has changed dramatically. Gone are the days when endpoint solutions and pattern file deployments were good enough to protect businesses. Today, data-stealing malware circumvents industry-standard enterprise security solutions by exploiting their weaknesses with sophisticated methods of attack that evolve rapidly and make use of multiple modalities. The cyber criminals behind data-stealing malware are smart and getting smarter, and they are after one thing: confidential, sensitive data they can turn into profit. They get it by: The results are not just lost data, but downtime, reduced productivity, costly clean up, and -- perhaps most important -- immediate and sometimes lasting damage to a company's reputation. Customer loyalty can plummet. And exposure to litigation threatens ongoing damage. While data-stealing malware becomes even more sophisticated, security professionals scramble to keep up, because industry-standard, endpoint antivirus solutions are falling short. Clearly, it's time for a new kind of protection, for security that gets to threats before they get to you. Simply put, it's time to rethink your enterprise security. In this eBook, Trend Micro - WPF gives an overview of data-stealing malware, discusses its ability to evade traditional security solutions, and presents a new approach to your business and your reputation.

  • SaaS-based E-mail Archiving Momentum Continues
    Recent ESG research suggests e-mail archiving is becoming a "must have" technology and all indicators point to SaaS-based solutions growing in popularity for companies of all sizes; a lack of skilled e-mail administrators and a variety of improved SaaS offerings are only two of the reasons why archiving may move to the cloud sooner rather than later. In February 2009, ESG published a report1 outlining two critical arguments: Medium-size business (100-999 employees) can benefit from e-mail archiving just as they have from other message management processes such as anti-spam and anti-virus. Software-as-a-Service (SaaS) solutions make it easy for medium-size organizations, which typically have limited IT sources, to get started with e-mail archiving. ESG believes that thesis is beginning to become reality. A recently completed and soon to be published ESG research study indicates that the number organizations using a SaaS-based e-mail archive solution has increased 350% over the past three years.2 There are other indicators as well: companies are using other message management-related services including backup, recovery, and security delivered via SaaS. These trends are likely to span organizations of all sizes looking to get their cloud computing initiatives off the ground (SaaS falls into the cloud computing category applications are delivered by an external service provider rather than via inhouse IT systems).
  • The Important Role of Storage for Success in Business Continuance: Driving Data Availability Up & Co
    Virtually every organization understands that its successful operation depends on the continuous availability of its applications. Most companies rely on internal applications--ranging from enterprise resource planning to payroll systems--to keep the wheels of their enterprise turning. They also depend on external-facing applications for everything from selling products to their customers to automating the supply chain with suppliers and partners. The failure of any of these mission-critical applications could be catastrophic to a business. The causes of downtime are numerous. Top-of-mind causes include fire and natural disasters such as floods, tornadoes, and hurricanes. More unexpected are causes such as power and cooling failures. But even more unforeseen are the failures that aren't thought of as true disasters: A fire in another part of the building can cause smoke and water damage in the best-protected data center. Human errors such as the faulty configuration of a switch or accidental discharge of fire-suppression material can also cause downtime. When a failure occurs, its scope can range from a system to a rack, from a room to a floor, and from a building to an entire site. A comprehensive business continuity solution includes not only the capacity to resume operations after a major but also the capacity to remain online during minor disruptions.
  • Rethinking Server Virtualization: Breaking Performance & Manageability Barriers
    Server virtualization is an ever more important tool for reducing cost, increasing availability, and enhancing business agility . But for many organizations, the savings that come from server consolidation are the primary reason for server virtualization . Many of virtualization's additional benefits--including built-in, cost-effective high availability (HA) and disaster recovery (DR)--require external shared storage with a comprehensive feature set to support HA and DR . Unfortunately, it is all too easy to spend the savings from server virtualization on inefficient storage systems . Because they overcome many of the cost and management limitations of traditional SANs, iSCSI SANs are becoming the preferred choice to support virtualized environments .

  • The Business Value of HP-UX 11i
    In Gartner's 2010 trends report, Daryl Plummer, managing vice president and chief Gartner fellow indicates that "For many organizations, the economic and budgetary challenges of 2009 drove important changes in the general governance of IT investment decisions, accelerating the trend toward greater accountability and transparency. According to Daryl "With a strong emphasis on business-case justifications, chief financial officers (CFOs) assumed a more active role. Although most organizations enter 2010 preparing for a return to growth, this financial oversight is unlikely to be lifted anytime soon. For IT leaders, greater fluency in the language of business has become a requirement."1 This white paper is designed to provide the initial basis for exploring the financial advantages of HP-UX 11i versus other platform alternatives, and empower organizations to consider all costs and benefits to help make better investment decisions. Utilizing TCO allows the decision makers to look beyond just the initial purchase price of the hardware and software assets, which historically has accounted for less than 30% of owning and operating typical server solutions, but is increasing with lower operating costs and improved business impact. TCO analysis can help IT make better business decisions by considering the total lifecycle costs and business of a proposed solution.
  • COMPARING HP-UX 11i v3 AND LINUX FOR HOSTING CRITICAL WORKLOADS
    This white paper presents a technical comparison of HP-UX 11i v3, Red Hat Enterprise Linux 5 (RHEL 5), and SUSE Linux Enterprise Server 11 (SLES 11) operating systems, focusing on their functional capabilities in terms of scalability, virtualization, reliability, and security. In each of these areas, the paper identifies some critical technical requirements, describes the significance of these requirements in current customer environments, and then shows how well HP-UX 11i v3 meets these requirements compared to the Linux systems. . Red Hat Enterprise Linux 5 and Novell SUSE Linux Enterprise Server 11 offer a full set of capabilities related to virtualization, security, and clustering for the Linux platform, narrowing the technical gap with leading UNIX systems and raising questions with users whether Linux systems are ready to take on the majority of UNIX workloads. However, UNIX remains one of the most trusted platforms in the industry, having proven its ability to support robust operations for decades. Moreover, UNIX continues to evolve as well, increasingly offering functions that were formerly only available for mainframes. Many users still view UNIX as the platform of choice for hosting critical workloads that demand the highest levels of reliability and security. Indeed, HP-UX still some technical advantages over Linux, which will be discussed in detail throughout this paper.
  • HP-UX Data Center Operating Environment and Integrity Server Blades for the Mission Critical Data Center
    HP BladeSystem Matrix with HP-UX is a robust platform for enterprise applications. It supports missioncritical UNIX for back end high availability as well as cost-efficient P roLiant server blades for complementary workloads. The flexibility of the management, virtualization and provisioning reduce deployment costs and simplify resou rce reconfiguration. Solid integration with storage and network infrastru cture from HP and other vend ors make it an ideal first step to take advantage of HP Converged Infrastructure. Today, the term "mission-critical" covers an ever-increasing set of data center workloads. As organizations evaluate options for their next generation infrastructu re, there are many reasons to look at new options. Current mission-critical infrastructure is frequently based on commercial UNIX environments deployed on la rge, expensive RISC servers clustered for high availability or disaster recovery. These environments are costly to deploy and manage, but up until there have been no good alternatives. Now, mission-critical capability can now be achieved in a more space efficient and flexible form factor � the blade chassis. HP has recently announced the BladeSystem Matrix with HP-UX, which leverages HP leadership in systems management, server blade design, and operating systems to p rovide a resilient infrastructure well suited to the data center.
  • HP-UX 11i V3: ENGINEERED FOR CRITICAL WORKLOADS
    This white paper presents a technical comparison of HP-UX 11i v3, AIX 6.1, and Solaris 10 UNIX operating systems, focusing on their functional capabilities in terms of virtualization, reliability, and security. In each of these areas, the paper identifies some critical technical requirements, describes the significance of these requirements in current customer environments, and then shows how well HP-UX 11i v3 meets these requirements compared to the other UNIX systems. HP-UX, AIX, and Solaris all offer very strong functionality today, with each leading in one area or another. But HP-UX stands out for its balance. It does not lag its competitors in any one area, and it breaks out with leading functionality in several areas valued by business users. One particular area of strength for HP-UX is the unique level of integration between virtualization, workload management, and high availability (HA) / disaster recovery in HP Insight Dynamics � VSE. The combination of HP-UX and Insight Dynamics � VSE gives customers the full benefit of virtualization in a highly available environment. In the newest version of HP-UX, online migration of Integrity Virtual Machines is up to two times faster than the previous release, and encryption is supported for live migration sensitive workloads.
