Analysis of Dell’s latest solid-state hard disk storage products

Recently, Dell to improve its data storage product line, added a solid-state drives (SSD), as well as the supply of the latest EMC unified storage. Increase the supply of solid-state hard disk so that a year ago, Dell acquired EqualLogic iSCSI product line, achieve a significant upgrade.

Dell’s new solid-state products pricing: 8 50GB SSD drive, chassis, dual controllers and software price of 25,000 U.S. dollars; 16 if the election SSD hard disk, then the price is 35,000 U.S. dollars. Price per GB of separately are 43.75 and 62.50 U.S. dollars, far below the enterprise-class solid-state product of $ per GB 200 to 300 dollars.

Samsung’s SSD drive performance may not be as good STEC Company. According to Dell’s senior manager Travis Vigil said, STEC’s SSD drive is a “more cost-effective” at the same time, allowing users to enjoy high-performance solid-state hard drive.

Vigil said that Dell has seen the original STEC per second input and output of up to 30000-40000, and the Samsung SSD hard drive is only 4000-6000, the actual value is the number depending on the load.

However, Vigil said: bare drive performance numerical existence misleading, in fact most cases, STEC with SATA drives and FC / SAS hard drives and controller share the same bandwidth, so actual performance will be affected.

The use of EqualLogic arrays, “you will be the controller and bandwidth resources available to the First Group – 8 or 16 – SSD hard disk, as well as expansion of our architecture, when you add in the SAN to other SSD nodes, you can improve the overall performance of linear and capacity “Vigil said,” Therefore, in practical applications, EqualLogic can ensure that no case of scramble for resources to ensure the performance of SSD, but at additional nodes to improve its performance, can also simultaneously each GB one-third of the cost savings. ”

Dell will provide PS6000S New SSD, Dell also will provide a blade server SSD. New Dell EqualLogic 6000 series replaced the original 5000 series. 6000 Series products include the entry-level PS6000E and high-density PS6500E, are based on the SATA and performance-oriented products; and PS6000X and PS6000XV is based on the SAS.

Dell said: These new arrays Writing performance target sequence to enhance up to 91% in order to read the speed also increased 29%. PS series of products can reach the maximum capacity of 576TB. PS6000 From 17,000 U.S. dollars.

Dell has also upgraded the incidental EqualLogic storage software, new features including support for Microsoft Hyper-V Smart Copysnapshots, according to Dell claims that the function to support the user “in a short period of seconds to quickly restore a virtual machine.” The software also supports RAID-6, Microsoft Exchange and SQL Server, Vmware, Citrix’s XenCenter.

The company also released a centralized console products, it can monitor dozens of PS Series equipment performance and status, Dell EqualLogic’s existing customers do not pay extra fees to receive the product.

Finally, Dell offers customers NX4 Products that EMC’s Celerra NX4. The unification of sales last year, EMC storage arrays also support the main storage data de-duplication and data compression.

NX4 support NAS, iSCSI and FC connectivity, but Vigil said, taking into account the situation of EqualLogic product line, Dell will make a point as a NAS products.

Vigil said that the product proves that Dell and EMC continued league.
