  • Storage Management Priorities: the Need of the Hour


    Most industries acknowledge that increasing IT Storage needs is a fact of life even in the face of economic downturn.

    Newer and more efficient ways of optimizing existing storage facilities are being explored as budgets are tight and capital outlay has been squeezed, writes Samantha Sai for storage.biz-news.

    Hu Yoshida, VP and CTO of Hitachi Data Systems, says: "In this economy, it will be important for IT professionals to stick to the fundamentals and focus on ROA and the ability to break even quickly."

    Major Storage investment priorities for IT Professionals in 2009 have been identified and listed unequivocally.

    Virtualized Storage services already in place require optimization. The direction of thinking seems to be virtualization of external storage and combining it with lower cost tiers of storage and thin provisioning.

    The stress is on curtailing data growth, while maximizing current investments, to get quick returns.

    The drive is to exploit the 70-80 per cent capacity that remains largely unused in existing storage.

    Unstructured data growth remains a persistent problem.

    Data storage optimization would require dealing with unstructured data on a war footing.

    The imperative is to archive unstructured data and map resources back to the bottom line of information needs.

    Tiered and priority ordering of information is identified as an essential activity that will help identify data that can be moved and archived without affecting critical data access.

    Consequently, the archiving solutions features being sought include simple process management, reduction in TCO and mitigation of risk.

    Active archiving solutions that are being put in place, have been recognized as integral to organization management initiatives and two tier storage systems are being moved to archival tier.

    Closely associated with the above processes is the data de-duplication process. Market conditions rule that duplicate data comes at a cost and de-duplication will save costs and improve productivity.

    Additionally, data compression and reduction in number of data backups are seen as methods to save costs.

    It is expected that as the year 2009 advances more and more companies will turn their attention from optimization and archiving needs towards Risk Mitigation and savings that can be had form power and cooling costs.

    Green, clean data centers will be seen as a real and urgent requirement.

    The need to stay ahead of energy issues will be dictated by upcoming regulations of EMEA and increasing purchasing requirements in the USA.

  • DataCore San Software Boosts Server Virtualization Support







    The latest versions of DataCore’s SANmelody 3.0 and SANsymphony 7.0 storage virtualization software were under preview at the recent VMWorld Europe 2009.

    The products are due to be shipped later this month with 64 bit software architecture and various new features for virtual servers, writes Samantha Sai for storage-biz.news.

    The company says SANSymphony is geared at enterprises aiming to virtualize their storage area networks, while SANmelody is for small Fiber Channel and iSCSI SANs of up to 32 TB.

    The virtual disk pooling, synchronized mirroring for high availability, load balancing, thin provisioning and other advanced features are exciting and will be welcomed by enterprises using the software.

    The 64 bit controller software supports large cache on the physical server up to a theoretical limit of 1 TB as against the earlier versions which supported only 20 GB cache.

    Jack Fegreus, CEO of Southborough, Mass.-based OpenBench Labs, points out that a terabyte of cache is "at the far edge of reality for most normal sites today", but given Moore’s Law, "1TB of cache may well be average".

    Today many organizations use as much as 256 GB of cache on average.

    This increased cache implies that there will be a denser consolidation of servers into virtual machines and performance of VM backups may improve by minimizing I/O to disk.

    The Transporter Option that comes with SANmelody and SANsymphony can also perform conversions between physical and virtual servers.

    This feature is significant as a server can be converted from a physical Windows box to a Microsoft Corp.Hyper V Image and then to a VMware ESX image.

    It can then be converted back to a logical unit Number (LUN) mapped to a physical server. This feature could be an advantage to people who are running multiple virtual servers with different operating systems.

    Themis Tokkaris, systems engineer with Arizona-based pest control company Truly Nolen, says that "it is also an open idea", adding: "If I’m not happy with ESX in the future, I’m not stuck with it."

    DataCore SAN offers its users the option of using a new free plug-in for VMWare Inc’s Virtual Infrastructure Client.

    James Price, vice president of product and channel marketing at DataCore SAN, claims that it will offer "cleaner visibility and easier to understand mappings and paths".

    He further points out that the upgrades will provide a way to reclaim free capacity on volumes using thin provisioning.

    DataCore SAN is not alone in this storage virtualization space.

    Many of the features offered by DataCore, such as 64 bit support, thin provisioning and so on, have been included in the packages of other vendors.

    Symantec Corp, Double-Take Software Inc and others offer 64 bit support for the data protection space.

    Compellent Technologies Inc also offered free space recovery for thin provisioning about a year ago. DataCore SAN’s offer, however, combines these features into a server-centric approach and appears to have set the trend for the future of networked storage solutions.

    However, Fegreus says DataCore’s combining these features into a server-centric approach looks like the wave of the future for networked storage as integration increases between SANs and servers.
