Squeak! - SSD Myths and Legends - "write endurance"
Does the fatal gene of "write endurance" built into flash solid state disks prevent their deployment in intensive server acceleration applications - such as RAID systems?
It was certainly true as little as a few years ago.

What's the risk with today's devices?

This article looks at the current generation of products and calculates how much (or how little) you should be worried.
read the article - SSD Myths and Legends
RAM based SSDs have been used alongside RAID for years - but flash SSDs are physically smaller and have bigger capacity (160G in 2.5") and are lower cost than RAM-SSDs and could actually be configured in standard RAID boxes. F-SSDs aren't as fast as RAM based products but a single flash SSD can deliver 20,000 IOPs - which when scaled up in an array - starts to look interesting. the article, storage reliability solid state disks

Music Publisher Chooses SANmelody

READING, UK - June 7, 2007 - The world's largest classical music publisher Boosey & Hawkes is using DataCore's SANmelody.

With 2 SANmelody disk servers, the system provides virtualisation, synchronous mirroring and auto failover for path and data, resulting in high availability. Paul Vernon, Head of IT, commented "We recognised that direct attached storage had distinct limitations. Constantly resizing and reallocating disk space and purchasing additional disk was becoming an ongoing challenge. We also knew that we needed to engage a more effective business continuity solution, to allow us to meet compliance and service agreements and allow 24x7 data exchange across the globe." ...DataCore profile, ...Boosey & Hawkes profile, SAN software

Data Compression Wiz Storewiz Secures $9 million Funding

SAN JOSE, Calif - June 5, 2007 - Storewiz Inc. today announced that it has closed a $9 million round of funding with leading venture capital firm Sequoia Capital.

The investment by Sequoia enables Storewiz to aggressively expand its sales and marketing teams to meet soaring demand for its realtime, transparent data compression appliances. The company has applied for 18 worldwide patents, which are pending for its NAS, iSCSI and Fibre Channel applications.

"Our investment strategy is to search out those companies that we believe will have the greatest impact in the industry in which they perform," said Shmil Levy, Sequoia Partner. "We believe Storewiz to be that market disrupter and feel that their leadership in the data compression industry is something that will not soon be overcome." ...Storewiz profile, Storage Software, VCs in Storage

Data Robotics Simplifies Consumer Storage Expansion

MOUNTAIN VIEW, CA - June 5, 2007 - Data Robotics introduces Drobo a fully automated storage robot designed for the small business and consumer market.

Drobo is a small desktop system that connects via USB. Inside are 4 bays that can accept any standard 3.5" SATA internal hard drives which just slide in without requiring any tools or carriers. Drobo acts as one large drive, making it easier to find what you've stored on it. When lights are green, your data is safe. When lights are yellow, your Drobo is 85% full, so just add or replace a drive. With red lights, replace or add a drive immediately. No software or configuration consoles are needed.

Drobo automatically configures itself for data protection. No choosing RAID levels or manually shuffling data between multiple external hard drives. When starting with more than one drive, if a drive fails, your data is safe and Drobo immediately moves unprotected data to any available protected space on remaining disks. ...Data Robotics profile

MicroNet Offers Instant RAID for SMBs

TORRANCE, CA - June 5, 2007 - MicroNet Technology today introduced the Platinum RAID Pro.

With upto 5 terabytes (price $4,499) it combines the highest capacity of any eSATA disk array on the market and requires no drivers to be installed.
The unit is factory-configured for RAID 5 so users can simply plug it in and immediately enjoy the benefits of parity RAID data protection.

The capacity breakthrough achieved by MicroNet is the result of design innovations in the host bus adapter and RAID controller to eliminate the 2 terabyte volume size limitation that restricts the available capacity of alternative eSATA-based disk arrays.

Solid Data Systems Sees 2007 as a Turning Point for SSDs

SANTA CLARA, Calif - June 4, 2007 - Solid Data Systems, Inc. announced today a market-driven shift in its corporate strategy.

With present day on-line and telecommunications databases struggling to keep up with ever increasing transaction rates, CEO Wade Tuma of Solid Data Systems is seeing renewed interest in Solid-State Disks as an alternative to traditional disks and farms of servers full of memory. "Customers with high-transaction rate database environments are no longer viewing Solid Data's SSD products as 'nice to have,' but as truly necessary components of their infrastructure."

During the last 5 years, the use of server main memory to cache highly used data or to keep all data in server memory has allowed most database managers to maintain acceptable throughput and services to their end users. However, as database requirements have evolved beyond the memory capacity of a single server, these solutions have become impractical and costly.

"As the cost of memory has continued to come down, we are seeing a natural evolution towards memory-based storage, but servers full of memory are not the answer," said Wade Tuma. "Now is the time to start considering the cost and simplicity of SSDs compared to a passel of servers full of memory. As an example, SSDs in 2007 provide 10x the capacity at the same price as SSDs sold in 2002 and eliminate the need to segment databases over multiple servers."

"In addition to the traditional problems of running large transaction databases, the epidemic growth of servers full of memory creates a challenge with regard to manageability, power consumption, space, and low MTBF" said Mark Hayashida, Director of Systems Architecture at Solid Data Systems. "Our customers benefit from using our trusted solid-state storage systems by reducing complexity, maintenance, and licensing costs."

Solid Data (who has key partnerships with HP, IBM, and Sun) intends to keep growing its markets in the telecommunications, trading and government markets. Solid Data was the first vendor to offer NEBS-certified SSD products and its exclusive Permarack feature means that every active component is modularized and can be serviced in minutes without de-racking. ...Solid Data Systems profile

Iterative Decoding will Increase Hard Disk Capacity

MILPITAS, Calif - June 4, 2007 - LSI Corp today announced that it is sampling new hard drive read channel chip.

The LSI TrueStore RC2500 for notebook and RC8800 for desktop applications are the industry's first available 65nm read channels to use iterative decoding. Iterative decoding is the next generation of recording channel architecture that enables significant improvements in signal-to-noise ratio for next generation of hard drives using perpendicular recording technology. This gain in SNR increases the amount of data that an HDD can store. LSI expects disk drive makers to begin shipping the new read channels in volume during the second half of 2008.

"Hard disk drive OEMs are hungry to increase the capacity per-platter of disk drives, but they have little appetite for power consumption," according to John Rydning, IDC's research manager for hard disk drives. ...LSI profile, storage chips
