whitepaper Provantage Credits Iomega's REV Drives for Meeting PCI Compliance While Delivering Dramatic Upgrades in Data Protection and Accessibility2008-07-11 Iomega
  Provantage Corp. is a leading online dealer of technology and personal computer products. Provantage's internal storage scenario mirrored those of its customers. The growing reliance on the Internet for business coupled with increased dependence on email resulted in storage requirements growing faster than ever before. Attuned to safeguarding mission-critical e-commerce, customer and product data, Provantage became concerned about relying only on tape-format storage devices to protect four redundant backup servers. Provantage deployed the newly-available Iomega REV 120GB Backup Drive to elevate its own backup and recovery processes, and began offering the REV 120 Drive to customers that required more native capacity in the same compact form.

whitepaper The Mathematics of RAID-62008-07-02 Zytor
  RAID-6 supports losing any two drives. The way this is done is by computing two syndromes, generally referred P and Q. The algebra used for this is the algebra of a Galois Field, GF(28). A smaller or larger field could also be used, however, a smaller field would limit the number of drives possible, and a larger field would require extremely large tables. GF(28) allows for a maximum of 257 drives, 255 (28 - 1) of which can be data drives; the reason for this is shown in the paper.

whitepaper Dell Storage Helps Navicure Reduce Disaster Recovery Site Deployment Time by 75 Percent2008-07-01 Dell
  Existing outsourced storage was too inflexible to keep up with Navicure's rapid growth and expanding Oracle database. The company also needed to automate disaster recovery to help ensure compliance with regulatory requirements. Navicure implemented a scalable, in-house Storage Area Network (SAN) using Dell EqualLogic PS Series Internet SCSI (iSCSI) arrays, and automated the planning, testing, and deployment of a disaster recovery solution using VMware Site Recovery Manager (SRM) software and Dell EqualLogic SRM Adapters.

whitepaper Booting Servers Directly From a Storage Area Network: The Benefits of SAN Fibre Channel and FCoE Connectivity2008-07-01 Emulex
  This paper discusses the capability of booting servers directly from OS images located on the SAN through a Fibre Channel Host Bus Adapter (HBA) or a Fibre Channel over Ethernet (FCoE) Converged Network Adapter (CNA). It describes the Emulex "Boot from SAN" implementation, and how it delivers a markedly enhanced level of manageability and availability, even in heterogeneous computing environments with distinct hardware and operating system requirements.

whitepaper Why Windows Enterprise Data Centers Are Choosing Emulex2008-07-01 Emulex
  Over 50% of the Windows-based SANs are Fibre Channel. Emulex is the dominant provider of Fibre Channel Host Bus Adapters (HBA) for Windows-based SANs because of a history of delivering high performance, scalable, reliable connectivity solutions that offer the finest software architecture and the best interoperability and support. In this paper for customers choosing to deploy a Unified Fabric, Emulex Fibre Channel over Ethernet (FCoE) Converged Network Adapters (CNAs) offer comprehensive Windows support.

whitepaper Enhanced SAN Connectivity for System Center Virtual Machine Manager 2007 and 20082008-07-01 Emulex
  Microsoft System Center Virtual Machine Manager (VMM) provides a comprehensive management application for Microsoft virtualized environments. Emulex 4Gb/s and 8Gb/s Fibre Channel HBAs and FCoE Converged Network Adapters (CNAs) work with Virtual Machine Manager to provide a fully integrated SAN solution for Windows Server 2008 Hyper-V, Microsoft Hyper-V Server and Microsoft Virtual Server 2005 R2. Using Emluex LightPulse Virtual HBA Technology and VMPilot, storage administrators can create Virtual HBA Ports with an associated NPIV-enabled volume mount point and attached LUNs.

whitepaper IBM Scale Out File Services: Reinventing Network-Attached Storage2008-07-01 IBM
  This paper focuses on the challenges of creating a scalable Network-Attached Storage (NAS) filer with hundreds of nodes on top of the IBM General Parallel File System (GPFS). The filer is created as a multiheaded data exporter over Ethernet and uses the Common Internet File System (CIFS) as implemented by the Samba open-source project and a Network File System (NFS) protocol server. Special focus is given to ensure the consistency of data in an efficient manner for applications that have complex access patterns from a large number of nodes. Also considered are the challenges of providing an extremely high-performance facility for exporting data in parallel and the demands of storing very large amounts of data.

whitepaper Undetected Disk Errors in RAID Arrays2008-07-01 IBM
  Though remarkably reliable, disk drives do fail occasionally. Most failures can be detected immediately; moreover, such failures can be modeled and addressed using technologies such as RAID (Redundant Arrays of Independent Disks). Unfortunately, disk drives can experience errors that are undetected by the drive - which the paper refers to as Undetected Disk Errors (UDEs). These errors can cause silent data corruption that may go completely undetected (until a system or application malfunction) or may be detected by software in the storage I/O stack. Continual increases in disk densities or in storage array sizes and more significantly the introduction of desktop-class drives in enterprise storage systems are increasing the likelihood of UDEs in a given system.

whitepaper HP StorageWorks Scalable NAS and HP Scalable NAS File Serving Software With CommVault Data Archiver for Tiered Storage2008-07-01 Hewlett-Packard
  Tiered storage management allows users to perform host-based, file-level data migration to tiered storage using a variety of network protocols for file movement. Every Hierarchical Storage Management (HSM) product on the market has different levels of dependencies on backup software, file systems and network protocols to facilitate this migration of data between tiers of storage. Satisfying these requirements using HP and CommVault software can significantly reduce cost and complexity to the HSM product installation. Key areas to consider when evaluating HSM products are the types of external media and how the product controls file migrations and recalls.
