Flash memory is a new trend for servers that handle storing data in CPUs

In order to maximize the speed advantage of solid-state storage, more and more vendors are moving flash storage to the CPU that is closer to processing http://www.aliyun.com/zixun/aggregation/17326.html "> Storage data."

Stec and OCZ Marvell Group also launched a flash memory device based on the pci-express (PCIe) bus interface last week. STEC Company is the first to enter the market, and launched its own hardware modules and software platform. The software platform can provide support for other solid-state storage vendor devices.

Solid-State storage has not only been viewed as a substitute for a centralized storage array of servers running disks, but solid-state storage has increasingly been viewed as a component within the server and used as a data or cache that needs to be reused.

Fusion-io is the leader of this trend. SetC now joins in as one of the largest providers of flash memory modules for SSDs.

According to the corporate Strategy Group analyst Mark Peters introduced. Solid-state storage leads to an increase in upfront costs, and additional costs if you build a server using solid-state storage. But investment is worthwhile, because the delay in solid-state storage is small, and in general it can also save costs for businesses.

Peters says most people are thinking that the cost per gigabyte means the entire storage cost. All are stored in order to use data stored in storage devices rather than for storage.

A storage architecture that allows faster access to data in the server (for example, PCIe based devices in the server) proves reasonable to increase costs.

Peters says Stec will offer its Enhanceio software to early adopters, which will add clout to PCIe based devices. Because it can work with other vendors ' hardware devices.

He also said that server-based SSDs are getting more attention, but may end up being the best choice for virtualized data centers in large enterprises.

Because it is pinned to the server, it leads to a lack of shareable. Centralized SSD provides more management flexibility and does not need to be distributed throughout the data center servers to play its part. For organizations with a smaller number of servers, the server based on solid-state storage caching is more efficient.

In Thursday, STEC launched the Kronos PCIe Solid-State Accelerator series and Enhanceio SSD cache software. The Kronos series of products are compatible with almost all similar SSD products in the marketplace. The company also claims that the two products can significantly reduce data center costs by supporting data center ultra-high-speed storage systems and accelerating other applications.

Kronos and Kronos Accelerator cards (ranging in size from 240GB to 980GB) can be used for primary storage within the server. But the main purpose of their design is to frequently access data cache replicas near the CPU to bring higher performance. Scott Stetzer, vice president of technology marketing at STEC, says this eliminates latency problems with switches, RAID controllers, and other components in traditional storage systems. STEC also claims that a company can reduce latency of hundreds of milliseconds to 30 nanoseconds if it migrates from a traditional storage area network (SAN) or iSCSI arrangement to a new technology.

SSDs cost more per gigabyte than traditional hard drives, but SSD provides faster data retrieval. This reduces the reliance on expensive high speed hard drives and technology to maximize drive speed. You can also avoid the purchase of a large number of unused disks.

STEC has taken additional steps on the Kronos module to improve server performance. The company claims that the card can reduce I/O tasks, while some similar PCIe products must be performed by the CPU. Stezer says this frees up more CPU resources and is used on other tasks. Especially in high-density virtualized servers.

This uninstall function is the difference between Stec and Fusion-io. Fusion is the leading manufacturer of solid-state storage markets. But this key differentiation feature of STEC company can help them to occupy market share. However, due to the existing system vendors and suppliers of the agreement. It is hard for Stec and other manufacturers to capture the Fusion-io market. The PCIe business is Stec's main goal, and the company has lowered its financial forecasts for the quarter since last month as it faces increasingly fierce core business competition. STEC's share price has fallen by more than 50% since February.

According to Stec's official view, Kronos Cards read and write sequential data at a 1.1GBps rate, and the Kronos Speed card rate reaches 2.2GBps. The Kronos Bi-turbo series has a maximum capacity of up to 1.95TB and a read/write speed of 3.6GBps. Stezer said Bi-turbo will be listed early next year, all products are divided into SLC (single unit) and MLC (multilayer) version, which can reflect the stec of high reliability characteristics, and provide five-year warranty for the product.

OCZ released a new PCIe SSD product prior to the release of the product in Stec in Thursday, and OCZ said the product was twice as high in performance as before. The SSD R4 of the Z series have two models of half height and full height, and the capacity is from 300GB to 3.2TB. Data can be read at a rate of 2.8GB per second. Unlike OCZ's previous products, this series is used primarily for servers rather than individual users.
