Author Topic: DOLBY SERVERS - questions x2 Allan Barnes Expert Film Handler Posts: 108 From: GRAND BEND, ONTARIO, CANADA Registered: Mar 2009 posted 10-11-2014 12:34 AM                        I'm swapping out one very similar 500gb hard drive in a series 100 DOLBY DSS... SEAGATE BARRACUDE "ES.2" for SEAGATE BARRACUDA ES"... I assume this will work... same brand and size only the model is slightly different. *** Dave you were correct about a BAD / DEAD HARD DRIVE preventing a RAID REBUILD *** QUESTION #2 .. in the Dolby model 200 DSS/DSP... it has "ports" for 8 hard drives rather than 4 on the early series 100 models. CAN I USE ALL EIGHT? If so how. Help and knowledge most welcome.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 10-11-2014 03:26 AM                     There's a list of drives tested by Dolby so known to work, your dealer should have it. Only 4 of the DSS200s drive slots are live.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 10-11-2014 05:28 AM                     you can use any drive, it would probably work but it hasn't been tested by Dolby. It may work well, it may not. Dolby won't support you if they see a no-qualified drive in the unit.  |  IP: Logged Allan Barnes Expert Film Handler Posts: 108 From: GRAND BEND, ONTARIO, CANADA Registered: Mar 2009 posted 10-11-2014 10:06 AM                        PETE YOU SAY "Only 4 of the DSS200s drive slots are live." CAN I "TURN ON" ALL EIGHT DRIVES SLOTS with CORRECT HARD DRIVES?  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 10-11-2014 11:59 AM                     Nope. The internal controller is a 4 ports only.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 10-11-2014 03:41 PM                     It is possible to change out the RAID controller to use all 8 slots (search the forum for that discussion on model numbers). Note, not all DSS100s can take the 1TB drives...thus far, all of the DSS100s I've tried it on have worked. Personally, I would stick with the Hitachi 1TB drives and avoid Seagate at all costs. I've had nothing but trouble with the Seagates. The HUA722010CLA330 has been VERY reliable for us and is an approved drive for Dolby (GDC and Doremi).  |  IP: Logged Mike Renlund Film Handler Posts: 71 From: San Francisco Registered: Feb 2008 posted 10-11-2014 05:53 PM                     Dolby recommends using the drives on the "approved list" because they have been tested with the different hardware platforms in several different conditions. Dolby servers use ENTERPRISE or SERVER class drives. Using consumer class drives is not recommended. Consumer and server class drives operate quite differently with regard to how they deal with read/write failures and attempting to recover bad sectors. Consumer class drives will take more time (than an enterprise class drive) to try and recover data from read/write failures. This can cause the RAID array to become degraded which may impact playback/performance. Enterprise class drives will try to repair the sector very quickly or reallocate the sector. This should not cause a degraded RAID array as often as a consumer drive with all of the performance impacts that come with that degraded array.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 10-11-2014 07:20 PM                        The 8-drive RAID controller for a DSS200 is 3Ware 9650SE-8LPML. More info on installing one can be found in this thread. I did so in August, and our DSS200 is running eight 2TB drives very happily.  |  IP: Logged Allan Barnes Expert Film Handler Posts: 108 From: GRAND BEND, ONTARIO, CANADA Registered: Mar 2009 posted 10-11-2014 10:04 PM                        MANY THANKS to ALL  |  IP: Logged
