  • ISCSI gains strength from servers
    is going to give you problems Resch said According to Asaro s presentation The State of iSCSI at the recent Storage Decisions conference in New York just 17 of some 511 companies surveyed by ESG already have an IP SAN deployed and just 20 of the respondents plan on implementing one soon Furthermore according to the ESG numbers 59 of the planned adopters of iSCSI and 24 of those who say they have no plans to deploy IP SANs cite performance concerns as the reason Roughly 26 of the nonadopters said they would only consider iSCSI if there were documented improvements in the performance of the protocol I m sure you can architect a solution in either the FC or iSCSI realm that would suit your needs said Tom Becchetti senior infrastructure engineer information technology who also asked that his company a national financial institution not be named The question is how easy or complicated is it going to be Becchetti who currently uses an EMC Symmetrix array and mainframes for high volume processing said he s been playing with iSCSI using EMC s Celerra network attached storage NAS box What he s liked about it so far is that IP incorporates more virtualization into the protocol especially device address virtualization With IP you re not as bound to a physical device as you are with a channeling protocol like FC Becchetti said I can definitely see a future implementation for iSCSI storage in our environment that uses a farm of different machines with virtualized addresses so a server could check out an iSCSI tape drive and then return it when it s done Hurry up and wait for the next tech refresh Other protocol enhancements such as 10 GigE and InfiniBand hold the promise of solving iSCSI s performance issues There s not much of a reason why iSCSI storage can t function in high performance environments today with the addition of InfiniBand according to Al Davis systems manager with MIT s BioImaging center The lab which collects studies and stores high resolution microscopic images of cells is phasing out an old Silicon Graphics Inc SGI FC RAID system in favor of hybrid iSCSI over InfiniBand storage InfiniBand and iSCSI are not nearly as mature as Fibre Channel Davis admitted But we don t always need 24 7 guaranteed uptime for long term storage What we need is huge throughput With 20 Gbps the promise is there for better performance going forward In support of applications like Davis the InfiniBand Trade Association last week ratified the iSER specification which will allow iSCSI systems to natively connect to InfiniBand But other users said they re still waiting for 10 GigE instead because as a memory protocol InfiniBand lacks the flexibility over distance that is a key benefit of IP However once 10 GigE arrives on the scene it ll mean another leapfrog over what server CPUs can handle meaning the return of TOE according to Kannel In our environment I

  • Archiving made uneasy by lack of metadata
    is all over the map That s what s holding up the acceptance of file archiving systems Users must set policies to archive files both current and old based on last access file size type or other available data and may do it by application or group and update the policies as internal processes or projects change Rick Chin until recently the data center manager at Pinnacle Financial beta tested Mimosa Systems File Systems Archiving FSA product part of its NearPoint offering earlier this year Chin says Pinnacle Financial went with Mimosa because it was a natural extension of using their email archiving product Our biggest need initially was for email archiving because it was just an out of control resource he says File archiving was equally out of control but it was less of a pain point because we had more general storage than email storage Chin says it was during Pinnacle s data migration to a new SAN when they realized how many of their files hadn t been touched for years but were still needed for documentation He says Pinnacle followed a policy similar to that for email with file archiving We had to define groups who all adopted similar policies like marketing or executive administration he says Chin says what he most appreciated about Mimosa s product was a setting that lets files be directly called up from the archive but not rewritten to disk Barry Murphy director of product marketing at Mimosa says they wanted to get away from the typical method of leaving a stub for a file which allows users access because the stubs got in the way of backup routines When a user double clicked the file would be restored and then have to be rearchived he says Instead users can choose to stub or not Ediscovery and compliance are big drivers of file archiving implementation but what I hear more as a driver from IT is cost savings getting their data off production servers and onto cheaper options says Murphy The next step on the file archiving path seems to be archiving SharePoint Murphy thinks continued SharePoint adoption will add more structured management to the content to be archived Campbell concurs he also sees an increase in SharePoint archiving as more companies adopt the tool which carries more meta data The ability to archive across all the unstructured content is really getting a lot more visibility he says It s not the data movement that s the hard part adds Foskett The hard part is actually figuring out what to move This story first appeared in Storage Magazine Dig Deeper on Data management software All News Problem Solve Storage infrastructure management doesn t have to be an infrastruggle Firms pleased with Red Hat Gluster as storage investment increases Geoscience Australia selects IBM 3592 cartridges as its tape migration Geoscience Australia selects IBM 3592 cartridges as its tape migration extends beyond ten years Load More View All Storage infrastructure management doesn t

  • Users tame backup systems with reporting tools
    ago our backup environment has grown dramatically Pardue said The SyncSort product s backup reporting capabilities came closest to Profiler s he said but fell short It was difficult to figure out what we were working with With a large number of jobs a task might fail but the only way you find out about it is to wait till the backup finished With Profiler according to Pardue If a task fails it shows up immediately on the Web interface The product he said will also show partial failures and allow him to drill into the backup logs to see when and where the task failed and troubleshoot the system The best thing about it is that it s vendor neutral Pardue said Now we can see at a glance what we re working with in our entire backup environment and jobs are color coded in green orange and red according to their status Pardue said it saves him at least an hour per day to have the system at hand And it has also allowed systems engineers monitoring critical systems overnight to troubleshoot backup errors themselves rather than calling him in That s another time savings Pardue said There are still some things Profiler won t do according to Pardue and chief among them is forecasting based on tape cartridges The product will predict backup volume based on client but doesn t currently relate that amount back to tape cartridges If the boss asks me how many tapes we ll need for the rest of the year it s hard to get an idea of that using this tool Pardue said Reporting tools gain traction expand markets Lately midsized customers are also beginning to embrace reporting tools Take for example Aptare customer York University located in Toronto The university backs up about 12 TB to 16 TB of data from its central headquarters on campus and as a publicly funded institution it is not in the same league with a company like Synopsys according to Ramon Kagan manager Unix services computing and network services But like Synopsys the university had been monitoring backups in house and had begun to find that process unmanageable We didn t have a good single point of information about our backups we didn t have a good capacity planning tool and we couldn t keep track using NetBackup of which tapes were needed for a particular restore Kagan said Since implementing Aptare s Storage Console Kagan said We can have nontechnical help desk staff checking on backups and monitoring the environment instead of backup techs running back and forth with tapes Bocada is also acknowledging a broader appeal for its products with the recently announced Bocada NOW a new pricing program that includes one two or three year subscription pricing and a simplified cost per client licensing model The program also includes a standard 30 day acceptance clause According to Drake Pruitt Bocada s vice president of marketing the program is specifically intended to

  • CDP overview
    your data It is also important to note that CDP is similar to snapshots in some respects but the two approaches are different A snapshot basically captures a system s state at a particular point in time much like CDP The difference is that snapshots are treated as an event being taken perhaps once a day twice a day or maybe even once an hour When a fault occurs any data generated between the last snapshot and the fault can be lost just as with any conventional backup By contrast CDP is approached more as an ongoing process recording all activity in real time and allowing restoration back to a precise point just preceding the fault Snapshots are often visualized as just one slice in a CDP timeline CDP products There are several key vendors in the CDP marketplace including Revivio Inc Storactive Inc recently acquired by Atempo Inc Asempra Technologies Inc Mendocino Software TimeSpring Software Corp Topio Inc and XOsoft Each vendor brings its own unique emphasis to the technology and its use in the enterprise Companies like Mendocino are touting the idea of manageability using event annotation to improve utilization of the CDP timeline Rather than selecting a restore point based simply on a timestamp an administrator can select a restore point that corresponds to a more significant system event Mendocino calls this event addressable storage TimeSpring follows the idea of manageability through offline replication allowing offline testing and inspection of data without impacting the production network This approach also allows protected data to be used for other purposes beyond backups including business intelligence or lab testing Storage Learning On The Go Download this overview and listen on your iPod or laptop Numerous vendors are applying CDP technology to specific applications For example Storactive has geared its LiveBackup software product for Windows based tasks like backup recovery and disaster recovery Storactive s LiveServ software protects Exchange servers for e mail backup and recovery TimeSpring s TimeData software is available in several versions supporting SQL NT file system and Exchange environments XOsoft provides WANSync software designed to offer CDP features between remote offices Companies like TimeSpring Storactive Mendocino and XOsoft implement CDP as software but Revivio favors hardware implementations in products like its CPS 1200 or CPS 1200i The CPS is a nondisruptive block based out of band appliance intended to protect mission critical enterprise applications without impairing application performance Applications of CDP The applications of CDP are as varied as the vendors products Some users employ CDP technology to avoid the time and trouble normally associated with traditional backups that frequently ran overnight into the workday through a weekend into Monday or even failed some way through the process forcing administrators to take more backup time or forego a backup entirely A substantial volume of valuable corporate data is often left on laptops or remote locations that aren t routinely protected by any backup strategy at all so some CDP users focus on supporting remote users In most

  • NAS buying Tip: Common sense approach to buying NAS
    topology is capable of handling the requirements NAS can overwhelm an existing LAN environment if there are large data transfer requirements If that is the case plan on scaling the LAN capacity to meet the NAS needs Understand what the users applications and administrators really require Many NAS features have no real value proposition other than distinguishing vendors from one another Feature function beyond what is required for the life of the storage must I repeat MUST have a quantifiable value proposition to the organization This means the benefits outweigh the costs Always specify the results and NOT the method in achieving those results This will force vendors to be creative in meeting your needs Be unambiguous on how and what must work with the organization s network management system This may include HP OpenView SNMP SMI S Java HTTP HTTPS or XML If no management system interoperability is required make sure the native management meets the skills and requirements of the organization Performance requirements must be clearly articulated from all involved with using or supporting the NAS A capacity planning exercise should be performed to calculate the scalability requirements on both capacity and performance Establish the level of RAID protection if any required as well as the OS file protocols such as CIFS Windows systems NFS Unix and Linux systems NCP Novell NetWare systems and AFP Apple talk for older Apple systems Clarify what type of DR and or business continuity planning is required and at what performance by the NAS system If block storage connection is required determine whether FC is required performance or iSCSI will suffice The iSCSI will run on the same fabric as the NAS itself and have a much lower cost Verify the organizational vendor requirements politically contractually support etc Identify all service requirements for implementation and support Make sure all costs are unmistakably identified in all vendors proposals Don t get hung up on the latest greatest technology trends such as global name space clustering WAFS or file virtualization All technology is a means to accomplish an end All that matters is that your needs are met within your technology budget and political restraints And that your tactical and strategic requirements are met If the technology doesn t meet those requirements then it is worthless to you Although this is a common sense approach it also requires plain old fashioned planning The alternative is just putting your fate in the hands of your favorite trusted vendor If you choose this path remember the immortal words of former president Ronald Reagan trust but verify Dig Deeper on NAS management All News Problem Solve Scale out network attached storage Options in today s market Hitachi Data Systems teams with Microsoft for unified computing platform Is NetApp preparing to defend unified storage UPDATE New channel focus leads to depature of NetApp Australia marketing director Load More View All Scale out network attached storage Options in today s market Hitachi Data Systems teams with Microsoft for unified

  • Pros and cons of remote mirroring for DR
    factor Remote synchronous mirroring is rarely deployed for circuit distances greater than 160km 100 miles With asynchronous remote mirroring local writes are completed and acknowledged before the remote writes Asynchronous remote mirroring is a store and forward technique that reduces I Os and wait delays allowing remote writes to fall behind the local writes This means the RPO for lost data can range from seconds to minutes and even hours in some cases Asynchronous remote mirroring is most often utilized when the remote site is a long distance from the local site The primary advantage of both synchronous and asynchronous remote mirroring is the minimal asynchronous to zero synchronous risk exposure in losing data during a disaster A secondary advantage is the potential for quick data recovery when a disaster occurs Remote mirroring doesn t require server agents and it provides heterogeneous server and application support Remote mirroring applications are often pricey the equipment is usually expensive and it typically requires at least twice the primary disk space and sometimes much more However when the lowest possible RPO and RTO are the requirement remote mirroring is the answer Another disadvantage is that remote mirroring doesn t prevent a rolling disaster data damage corruption or accidental deletion If data is corrupted damaged or deleted at the primary site it will also be at the DR site Some asynchronous remote mirroring products timestamp each transaction and allow recovery to a point in time before the corruption or deletion occurred but they re exceptions to the rule This means procedures other than remote mirroring must also be implemented to allow for recovery of corrupted damaged or deleted data Other disadvantages include lack of support for heterogeneous arrays no support for internal storage and nearly no application and file information Less expensive alternatives to remote mirroring can also provide the lowest possible RPO and RTO They re generally continuous data protection CDP products and include time based continuous snapshots automated backup replication of changed data and automated generational change distributed backup They offer a lower TCO than remote mirroring support heterogeneous storage and provide better rollback capabilities But they usually require installing and managing agents Read the whole tip in Storage magazine For more information Tip When and when NOT to use mirroring Tip How to get cost effective disaster recovery Tip Which is better Cheap mirroring or RAID About the author Marc Staimer is the president of Dragon Slayer Consulting Dig Deeper on Data backup and protection All News Problem Solve Cloud storage boom as users rush to outsourcers Incriptus heads for the enterprise A sneak peek at Avamar vCloud Protector Storage considerations for containerised data centres Load More View All Cloud storage boom as users rush to outsourcers Incriptus heads for the enterprise A sneak peek at Avamar vCloud Protector Rackspace s cloud storage outage Load More View All News Storage considerations for containerised data centres Solid state hard drive data recovery is not easy How to beat Bit Rot How to
