Hi Barry, <div>&nbsp;</div> Couldn't agree more - SVC has the credentials and track record. <div>&nbsp;</div> I hadn't heard about the STAR/ DART offering you mentioned. Can't find any other information on it except for this IBM France presentation: http://www-05.ibm.com/fr/events/JT_fev_2010/JT_Q1_2010_SVC_TPC_STAR_thin_prov_and_right_tieirng.pdf <div>&nbsp;</div> Is it a business partner tool? <div>&nbsp;</div> Interestingly, the presentation mentions that sub-LUN tiering to SSD will be GA in SVC 6.1 2H 2010 (Pg33). Will this automation be driven by TPC or built into SVC itself? The reason I ask is that TPC (Standard or Disk) are generally too costly. It would be a pity if IBM kept this feature to an exclusive few with deep pockets. <div>&nbsp;</div> Thanks, <div>&nbsp;</div> Craig

Hi Craig, <div>&nbsp;</div> The STAR/DART offering is a service offering where we can come in and run some analysis of your environment, work out the needs of your applications from a performance perspective and then make some recommendations as to what data is on the wrong tier today. Generally too high a tier, and thus help you to migrate down to the right tier. This uses some of the features of TPC with additional analysis tools the service teams have to enable customers to reduce their reliance on Tier1 storage. i.e. get data on the right tier. <div>&nbsp;</div> The sub-lun automated tiering is coming later this year as I've stated before and is built into SVC itself. TPC can be used to monitor metrics about the function itself, but is not required to use of the feature. More details will be forthcoming later this year - and watch out for the same function coming to a DS8700 near you soon! <div>&nbsp;</div> Barry

fyi to all, the leaks are happening now on EMC's "vision" <div>&nbsp;</div> http://chucksblog.emc.com/chucks_blog/2010/03/this-changes-everything.html <br /> http://www.channelregister.co.uk/2010/03/15/emc_daad/ <br /> http://silvertonconsulting.com/blog/2010/03/11/caching-daad-for-federated-data-centers/ <div>&nbsp;</div> What I don't get is what is the benefit for me right now to add svc or emc yy to an old frame? I need to consolidate EMC frames, 25+ down to 6. 2 PB of data. EMC is a standard (which I cannot change). Only until I have to change again in the next storage cycle in about 4-5 years will SVC or EMC's YY help me in a migration, moving frames in and out of a virtualized storage layer without affecting applications. Am I correct about this technology? <div>&nbsp;</div> <div>&nbsp;</div> <div>&nbsp;</div> <div>&nbsp;</div> <div>&nbsp;</div> <div>&nbsp;</div>
