The introduction will be part of a larger set of announcements concerning Dell's data center strategy, taking place at an event in San Francisco on Wednesday morning. Dell said it is focused on combining servers, storage and services, all optimized for virtualization, in a single architecture. Like other major data-center vendors, such as IBM and HP, Dell is facing a new end-to-end competitor in Cisco, which last week announced its first blade servers.
Most storage architectures installed in enterprises today weren't designed to work with virtualized servers, which are being widely adopted. The new EqualLogic PS6000 Series, an upgrade to the already virtualization-oriented PS5000, includes additional features in that area along with higher performance and a new SSD (solid-state disk) option. Prices remain the same, with disk-based systems starting at US$17,000.
Dell redesigned the controller for the PS6000 series for higher enterprise performance, delivering twice the cache size, four Gigabit Ethernet ports and a faster processor, according to Travis Vigil, a senior manager of the EqualLogic line. The new controller can perform 29 percent faster read performance and 91 percent faster write speed, he said.
More significantly, the company has brought SSDs to the product line. The PS6000S line is designed to offer the low latency and fast data access of SSDs at one-third the price per gigabyte of competing platforms, Vigil said. Dell expects enterprises to use SSDs for applications such as databases and to support virtual desktops. For the latter, IT departments can set up OS images on a centrally controlled platform for individual employees to access on their PCs or other devices. The high speed of SSDs -- three times the I/O operations per second and one-third the latency of a typical disk-based system -- can deliver desktop images in a way that's easy for individuals to use, he said.
The PS6000S is available in a 400GB version with eight 50GB SSDs and an 800GB version with 16 of the drives. Prices start at $25,000.
