IBM Launches New Product Line
An anonymous reader notes that "IBM has launched its new product line of storage devices: the DS6000 and the DS8000. The results are quite impressive, with the DS6000 being rack mountable, 3U, and ONLY 125 pound storage device that will hold up to 67.2 TB! The DS8000 is equally impressive, with 6x performance of ESS 800 (Shark), making it the most powerful storage system to date. "
I dunno. 67Tb in thirteen 3U 16 drive units doesn't sound all that impressive. Maybe if you could fit 100Tb in 50U of space I would be impressed. If this could even scale that high you could only fit 80Tb in that amount of space. 3U for 4.8Tb of raw storage is not a big deal. You can build your own low quality system with that kind of capacity yourself out of cheap disks. Obviously not with the same performance though.
Although I will admit that this is a very fast product with decent redundancy. Although I generally believe dealing with redundancy at a higher level with software is much more flexible than controller level redundancy. And cheaper.
Fibrechannel drives sound neat and all, but if someone can fit 3x as many "lower end" drives in the same amount of space that's lower cost, higher redundancy, higher capacity and higher performance. I'm sure they are good for something though, else IBM wouldn't have such a sales drive behind them. *snicker*

To reach solid decision's, youl'l need more infermation then the slashdot writeup supplies. Like this article featured on linuxtoday.com, which are surely slightly more independent than IBMs' press release's; (click complete story under the summary) From it:
... "You can run different operating systems, even different releases of operating systems on isolated LPAR's. Rock!"
The DS8000 is unique in the industry because it features two logical partitions too run management or utility applications such as the companies SAN Volume Controller and Tivoli Storage Manager for backup and data management.
That sounds like a pretty interesting feature. Anybody's in the industry care to comment on the portential for these new development?
This article on lightreading.com elaborates a little more.
IBM's DS8000 handles virtualization different then the competition. While HDS does virtualization in the controller and EMC plans virtualization on intelligent switches IBMs' new system does virtualization at the chip level (see EMC on Virtualization: Wait for Us ). Using the Power5's IBM Virtual Engine, the DS800 can divide servers into logical partitions (LPARs). Each LPAR can run different storage systems that run separate code.
Thats a truly impressive level of flexibility their. And of course, its great for Linux, the ability to run multiple OSe's in hardware on one box play's to Linuxes strength's and deal's a blow to Microsoft's monopoly lockin strategy. What Im really shocked about is that there slashdot writeup included only some bland "durr big numbers" product placement, while IBM is effecting an interesting Linux-related change's in the marketplace's if you look a little deeper.

When I hear someone suggest to roll your own anything, I want to scream and run as they probably haven't worked a day in a real production environment. I'd like to see you roll your own, manage, and support a multiterabyte storage system and then decide by yourself whether it was worth it or not (assuming you're lucky and get a chance to do so, after not being fired because something has gone wrong and ate your data or caused downtime)
As for this particular case, this system was obviously designed to efficiently manage vast amounts of storage. It is not worth buying if you only need a 580GB of storage. Besides, no one pays the list price in the enterprise storage market. No one also buys IBM's enterprise hardware just because they think they need the hardware alone.
