  • NAS management software purchase considerations
    businesses but it may become more problematic for smaller organizations with limited server availability especially if the available server is already running other software As one example Adaptec Inc s Snap Server Manager software requires a Pentium III 133 MHz processor 128MB RAM Snap Server GuardianOS v2 6 or higher Snap Server SnapOS v3 4 or higher and Java Virtual Machine V1 4 1 See the product specifications page for other details Evaluate the tool s hardware interoperability It s often cumbersome and impractical to use a different management tool for each NAS device so companies must select software that can support numerous NAS devices across the organization In many cases this means committing to NAS products from a single vendor or selecting a tool that can support NAS devices from different manufacturers Recognize the scope of NAS appliances or gateways supported by the software and determine whether its coverage is adequate for the organization Evaluate the tool s management interoperability Many NAS management tools can function through network management tools already at work in the organization such as Hewlett Packard Co s OpenView SNMP SMI S Java HTTP HTTPS or XML This can improve management efficiency by letting administrators run NAS management tools through their existing management platform Otherwise an administrator will need to learn and operate the NAS management software as a separate tool and process This may not pose a problem for limited NAS deployments where NAS management overhead is limited but can become a serious impediment for heavy NAS overhead Consider the level of automation available Management software is more valuable when it can automate many of the most common storage management functions including resource location identification provisioning software updates and routine maintenance functions NAS management software should improve efficiency by scheduling important tasks during off peak hours like software updates or backups Management tools should provide comprehensive notifications and alerts in response to critical storage conditions such as low available storage Some NAS management tools can also offer assistance with capacity growth This helps administrators track storage utilization and plan upgrades to stay ahead of needs a key issue in preventing application downtime and maintaining performance Consider the cost impact Beyond the up front cost of acquisition it s important to remember that some features and functionality may be optional and this typically incurs an added cost to the enterprise Many software tools also require yearly license fees that will greatly multiply the tool s cost over time Weigh the software s value against its total cost of ownership TCO which should include all necessary onetime and recurring fees Consider the management skill set Effective storage management requires a working familiarity with the tools in use New management tools or tools from different vendors demand training and practice for proficiency Be sure to implement adequate training for administrators and other key IT staff In some cases training is included as part of the acquisition cost If not the training costs should be included in the

  • VMware vSphere shared storage guide
    The HP models are more expensive than some of the other affordable storage devices but they have many advanced features and a solid architecture that is based on HP s DL servers IOMEGA Iomega is owned by EMC Corp and offers several affordable shared storage devices from their small two drive ix2 200 unit all the way up to their newly released twelve drive ix12 300r unit The Iomega models offer tremendous value with many great features and they all support iSCSI and NFS Because of EMC s strong relationship with VMware all of the Iomega models are listed on the vSphere HCG The Iomega models are available with disks in varying configurations However you must use Iomega hard drives because they use a proprietary drive sled with a special security screw head that makes it difficult to remove from the drive The ix4 200d is one of their most popular units while the 4 TB ix12 300r adds many features like redundant power supplies bigger cache and four network ports NETGEAR Netgear sells a wide variety of shared storage devices in its ReadyNAS family from their small ReadyNAS Duo model up to their largest model the ReadyNAS 4200 The ReadyNAS models all have advanced features such as the ReadyNAS Vault feature that can replicate data to another ReadyNAS device or FTP site Most of the models support both iSCSI and NFS protocols as well as many conventional RAID levels They also support Netgear s proprietary X RAID2 that allows for easy expansion as well as using different drive sizes in the same RAID group Most of the ReadyNAS models are listed on the vSphere HCG Most of the ReadyNAS models can be purchased with or without disks QNAP QNAP Systems has a very large line of affordable shared storage devices from small two drive units to larger eight drive tower and rack mount units with 11 models listed on the vSphere HCG All of the units support both iSCSI and NFS and many also include advanced features that are listed in this comparison chart The QNAP shared storage devices all have hot swappable drives provide the drive sleds and support third party hard drives You can also expand or increase RAID levels while the unit is running A convenient feature that QNAP has is called a Virtual Disk Drive VDD that allows the QNAP unit to connect up to eight external iSCSI targets and present them as one stacked disk The QNAP device becomes the stack master for the other iSCSI targets and servers that connect to the QNAP see one stacked disk instead of the multiple iSCSI targets that make up the stack Some additional features include support for IPv6 multiple NIC bonding modes LUN masking Wake on LAN and Active Directory integration The only units with redundant power supplies are the eight bay rack mount units TS 809U RP and TS 859U RP The prices range from 599 for the smaller two tower drive units to 2 099 for the larger rack units The QNAP units all come without drives but you can add any brand size SATA drives that you want to them SYNOLOGY Synology offers a wide range of more than 10 affordable shared storage devices ranging from simple one drive units all the way up to five drive units that can be further expanded with an add on five drive expansion unit All DiskStation models have a rich selection of features and they all support both iSCSI and NFS Synology also includes its DiskStation Manager Web based interface that is used to manage the DiskStation units and has some impressive features such as Active Directory integration link aggregation built in firewall resource monitor and a wide variety of backup options In addition to supporting the normal RAID levels Synology has its own Hybrid RAID that supports using drives of varying sizes in a RAID group The only DiskStation unit currently listed on the vSphere HCG is their high end DS1010 model which is priced at 999 However while not listed on the HCG the DS410 and RS409 units are also good units to use with vSphere All of the Synology units can be purchased without hard drives and there are also some packages available that have drives included THECUS Thecus Tech Corp has a large family of storage devices with seven of them listed on the vSphere HCG All of the units support iSCSI and NFS and have many advanced features that you would normally find on more expansive SANs This includes support for snapshots data replication using the company s proprietary Nsync dual disk modules redundant power supplies link aggregation and online RAID migration and expansion Many of the Thecus shared storage devices support a 10 Gb Ethernet adapter to the single PCIe x8 expansion slot that is present in some models All models support using SATA disks but they have a few models N7700SAS and N8800SAS that support using faster SAS disks as well The Thecus models can be attached to one another in a stacked mode to provide greater expandability and they also support thin provisioning The lower end Thecus N4200 device starts at 799 and goes up to 1 999 for the N8800PRO model Also the units are all available without drives so you can add your own drives and all drives are hot swappable TABLE OF VSPHERE SHARED STORAGE DEVICES FOR SMBS The table below represents a breakdown of the shared storage devices from the vendors discussed previously but this does not include all of the models available from each vendor The table shows the number of drive bays whether they are rack mountable or standalone tower units whether they support iSCSI and NFS or not the number of network connections how much memory they have the maximum internal capacity when using the largest drives if they are on the vSphere HCG or not and the approximate retail price of the lowest end unit Device of bays Rack iSCSI

  • EMC plans VMAXe vBlocks
    in general is a huge growth opportunity for us VMAXe will help EMC he said especially when sold as part of vBlocks the pre configured stack of virtualised storage network and computing sold by the VMware Ciso and EMC VCE alliance Gallagher feels service providers in the region will appreciate vBlocks based on VMAXe as organisations look for trusted providers of data centre facilities that offer comparable flexibility to public cloud providers but greater opportunity for dedicated services and customised SLAs Lots of our customers have built clouds but the trust factor is not there to take it to a public cloud provider But they will turn it over to a top tier service provider if they know it is safe They can t do it all in their own data centres but service providers can bring them what they need Gallagher is therefore hustling to speed the creation of the new vBlocks We would like vBlocks based on VMAXe tomorrow Gallagher said We are working with our friends at VCE and expect it in the next twelve months and we are optimising to be faster than that I would like to see it as early as the beginning of next year Gallagher said he is also responsible for EMC s storage clustering vPlex technology and said he expects it will appear in vBlocks based on VMAXe EMC vs VSA Gallagher s visit to Australia came just two days after VMware launched its vSphere storage appliance VSA a virtual array to support VMware IBRS analyst Kevin McIsaac hailed VSA as a game changer that will eventually supplant mid range arrays a position Gallagher refuted Across all our products there is value that we bring in copy services in automated tiering in replication both local and remote Mid tier arrays still bring that value to the enterprise Gallagher said I think VSA is geared towards small business Will it ultimately scale Yes everything scales over time But I think if you look at storage there has been this idea storage will be commoditised Ultimately all things do to one degree or another But the problems we solve still need pretty sophisticated engineering and with this automated data placement it takes intelligence to do that We have six years of analytics about how applications access data We have petabytes of trace data to analyse Gallagher also feels that large virtual arrays may not be the best configuration for applications All of those things our arrays do take compute cycles The challenges of doing that in the virtual world is that you are leveraging compute cycles for the application and compute cycles for managing information Arrays provide useful separation he said But if you are in a small environment there is no reason a VSA device would not fit your purpose for that environment 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

  • Thin provisioning will beat storage virtualisation
    application is nearly always inaccessible to others That exclusivity of access means administrators tend to be very conservative when they provision an array Many will therefore decide that an application which regularly uses 50GB of storage should have 200GB of capacity provisioned to make sure it has plenty of overhead available in case of surges This practise while commendably far sighted has the unfortunate effect of locking away 150GB of storage capacity for a rainy day rather than making that capacity available for other applications Thin provisioning does away with this waste by allowing administrators to over provision for their applications This has three benefits The first is that according to Ovum storage analyst Tim Stammers it doubles the capacity of every piece of storage you buy Another is that operators of several applications can over provision them all safe in the knowledge that thin provisioning does all the juggling required to indentify and utilise the spare capacity in each application s allocation of storage The other is that users need only provision an application once even if they have less physical storage than they provision This trick makes it possible to provision an application to use 500GB even though a storage array only contains 250GB As the application nears the physical capacity of the array more storage can be added without needing to perform additional administration chores While thin provisioning is not yet widely used its adoption will accelerate rapidly as vendor support widens and more storage administrators become aware of its benefits McIsaac says Over the next 18 it will become as pervasive as other array based virtualisation features such as RAID and snapshots McIsaac s prediction is already coming true HDS and Dell EqualLogic have both brought the technology to market and NetApp plans to do likewise EMC has pledged to bring the technology to all of its arrays 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 scalability considerations A beginners guide to iSCSI 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
