  • UPDATE: Storage Networking World cancelled
    last year received feedback to the effect that the event should shrink from one day to two SNIA hoped that a one day event could be run in more than one city But Terrapinn s Rubens says that the cost of a two day event is only slightly more than a one day affair Moving an event to different cities however would add more cost than sponsors are willing to incur and was therefore not a viable commerical option Rubens also points out that Terrapinn does not believe in the one day format and does not run them worldwide The result was a compromise decision for a one day event in one city only a less attractive proposition to marketers that may have been one reason Terrapinn found it hard to attract sponsors Yet Terrapinn s level of engagement with potential sponsors may not have been comprehensive Mark Heers of Network Appliance told searchstorage com au that he was only approached by Terrapinn two weeks ago As he was waiting to receive his new budget allocation he had not yet decided whether or not to sponsor the show but leaned towards doing so Heers does not however feel that the event represented exceptional value Sponsorship was identical in price to last year s two day show he said That made it a very expensive one day event from a sponsorship point of view Nonetheless Heers says he is disappointed the event will not go ahead He shares that sentiment with SNIA Chairman Jacob Van der Eyk who told searchstorage com au that he respects Terrapinn s commercial decision but still feels the region deserves a storage event If they cannot make a commercial success of it they should not proceed he said We have been and are in discussions to see what happens as the dust settles SNIA ANZ believes we need to have a flagship conference in the region It is a key part of our educational objectives It is nice to have a major flagship event but we need to remember SNIA is an Australia and New Zealand organisation Feedback we have received is that a smaller more targeted more focussed event could be needed I am in touch with representatives from the end user community and we are asking what would work for them We re confident we can do something relevant Dig Deeper on Data storage vendors All News Problem Solve SGI adopts hybrid storage for clustered NAS Symantec aims Data Insight 3 0 at unstructured data management IT data storage priorities 2012 Virtualization dedupe and cloud NetApp announces Big Data solutions as market grows Load More View All SGI adopts hybrid storage for clustered NAS Symantec aims Data Insight 3 0 at unstructured data management NetApp announces Big Data solutions as market grows I spy web servers which don t lie Load More View All News IT data storage priorities 2012 Virtualization dedupe and cloud VNXe the jewel as EMC caned for broken record VNX

  • Has MAID got it made?
    archives a scenario in which SATA disks are preferred despite their short mean time between failure MTBF because they simply won t be running long enough for MTBF to become an issue That usage pattern helps make MAID a competitor for tape libraries as an archival technology on reliability grounds And even though it can take ten seconds to spin up a disk so it can once again deliver data ten seconds means MAID is a strong competitor for tape on the speed front too This makes MAID as a useful contributor to tiered storage and information lifecycle management efforts too Add in the fact that MAID arrays are also a nice shade of green switching off unused drives means power consumption is well below that offered by traditional disk devices and the standard seems to offer a more than useful option to the storage professional Yet despite these are powerful arguments MAID is seldom deployed and more or less unknown One reason is that there is no MAID standard Vendors like Copan Systems have made MAID an integral part of their storage systems but have done so alone Hitachi Data Systems Marketing Manager Tim Smith advanced the lack of standard for the reason his company does not oficially use MAID but says the company s products use MAID like practises as part of their tiered storage implementation that sees some third tier disk spun down when not in use Others however are starting to promote MAID Fujitsu for example recently introduced MAID into its Eternus 4000 and 8000 SAN arrays making it the first vendor to use the technology in a mainstream storage device The company says power savings of 25 are on offer advancing this figure as the main reason for adopting the technique But not everyone is convinced that MAID is truly useful at least as an archive questioning why users would want archives that remain online or as near line as a spun down disk The feedback I m getting is that the dollars do not work out says EMC s Clive Gold It does not work for long term storage and for off line tape is still considerably less expensive So my take right now is that MAID is a solution looking for a problem Dig Deeper on Primary storage and storage hardware All News Problem Solve Advantages of using an object storage system Dell storage products roadmap includes server flash primary dedupe EMC sees bright future for hybrid SSD cloud models Hitachi Data Systems moves into unified storage architecture with HUS Load More View All Dell storage products roadmap includes server flash primary dedupe EMC sees bright future for hybrid SSD cloud models Hitachi Data Systems moves into unified storage architecture with HUS Week in review podcast EMC goes cloud building and more Load More View All News Advantages of using an object storage system FC SAN vs iSCSI SAN Part 1 Reliability and performance FC SAN vs iSCSI SAN Part 2 Cost and

  • Capacity planning tools require serious purchase consideration
    the time to gauge a capacity planning tool against your own internal processes It should provide the necessary information at a level of granularity that is most conducive to your particular budgeting purchasing process Determine the role of software agents Most capacity planning tools require the use of agents For example StorageConsole software from Aptare deploys an agent on the master server while NetWisdom from Finistar touts agentless operation Since agent software requires more maintenance and attention storage administrators may prohibit the use of agents If your organization s IT department prohibits the deployment of server agents focus on agentless capacity planning tools and verify that your planning tool can collect the required suite of data across your storage platforms without agents However remember that reporting may not be as detailed or comprehensive as the reporting from capacity planning tools that rely on agents Consider the analytical capabilities of the tool Understand exactly how the capacity planning tool analyzes information For example some specialized tools may simply examine the storage capacity available on network servers or measure network bandwidth More versatile tools may actually be able to model the needs of a particular application such as the resource capacity required for a new distributed application Some capacity planning tools can also predict the performance and availability of applications relative to storage Consider the reporting capabilities of the tool Once the capacity planning tool completes its analysis it needs to generate a report that provides pertinent details For example some tools can report on storage space usage and storage performance such as I Os throughput response latency I O size reads and writes Other tools might provide application centric server centric storage centric or network centric views of the environment Every organization is different so look for the reporting details that you actually need Test the tool for predictive accuracy If you expect the capacity planning tool to help with modeling or predictive analysis even what if scenarios make it a point to test the tool in a lab setting that mimics your real environment Not only will testing help to identify the most accurate tool it will also afford an opportunity to evaluate the user interface and steps needed to conduct a model Inaccurate or difficult modeling will really impair your use of the software Another way to verify a tool s accuracy is to speak with other users Consider capacity planning features in an SRM suite Although dedicated capacity planning tools remain popular there is a growing trend to bundle capacity planning features in a broader storage resource management SRM product or suite of tools Purchasing a suite can sometimes save money over buying elements of a suite separately and avoid potential software integration problems because the components of a suite are already known to work together Some organizations purchase a capacity planning tool when a short term tactical problem needs to be solved or opt for an SRM or other software suite when longer term strategic planning reporting

  • EMC prepares storage 2.0
    Tucci declined to say when these products will be announced but said development is under way He also said that EMC feels many of its customers may not yet have a full appreciation of the company s offerings and how they can ease storage management Responding to a question from SearchStorage com au to the effect that storage users generally complain of unwelcome complexity Tucci said that If customers used the tools we have things would get easier One of those tools he added is the company s Avamar data de duplication software which he said has great potential to slow the proliferation of data Even though this means companies will require less storage hardware Tucci said simplification of storage environments is an area in which EMC plans to lead the market Price is another field in which the company has changed its tune after noting that customers often resent the level of storage spending required to keep up with the data they create Customers do not want to pay a lot for good reliable storage he said half joking But today on every tier we are priced very competitively In the past we had a fair reputation for charging a premium Despite the lower pricing Tucci said EMC s growth prospects remain strong although the company expects that expanding sales of software and services will be the key to keeping margins high Tucci will look to VMware to provide much of the growth on the software side of the business and hopes success in that sphere will boost the company s share price which has traded in a narrow band since early 2004 Tucci said he found the company s share price aggravating but added he believes the company is generally in good health and has excellent growth prospects There is a horrendous amount of stuff to be stored he said We ll be fine Dig Deeper on Data storage vendors All News Problem Solve SGI adopts hybrid storage for clustered NAS Symantec aims Data Insight 3 0 at unstructured data management IT data storage priorities 2012 Virtualization dedupe and cloud NetApp announces Big Data solutions as market grows Load More View All SGI adopts hybrid storage for clustered NAS Symantec aims Data Insight 3 0 at unstructured data management NetApp announces Big Data solutions as market grows I spy web servers which don t lie Load More View All News IT data storage priorities 2012 Virtualization dedupe and cloud VNXe the jewel as EMC caned for broken record VNX marketing Sun ZFS 101 View All Problem solve ADS BY GOOGLE Latest TechTarget resources CIO AU Security AU Data Backup Disaster Recovery SMB Storage Storage Channel Search CIO com au Internet of Things Food safety apps set to emerge Food safety could emerge as a key application for the Internet of Things in the coming months providing real time visibility in Cloud security culture a building block for today s businesses As organizations today move more data to the
