New software tools from BiTMICRO Networks mean You don't have to become a storage Einstein to use SSDs effectively

SAN DIEGO, Calif. - July 29, 2003 - At SIGGRAPH 2003, BiTMICRO Networks announced today the availability of the E-Disk SafeCapacity software suite to complement its entire E-Disk solid state storage product line.

In most storage systems, a small set of data files account for a disproportionately large amount of disk I/O. When identified, these "hot" files will most often be database log files, heavily hit indices and tables - all excellent candidates for migration to solid state storage. SafeCapacity-Hotfile determines the most often accessed files and displays a list of these files in a descending order of access. Using SafeCapacity-Migration, administrators transparently relocate these hot files to the fastest storage available in their environment.

The fact that files are relocated to faster devices is completely unobservable to both users and applications. The appearance and attributes of the files remain the same, while access to these files is transparently redirected to the high-performance storage without any performance degradation. This approach eliminates the need to reconfigure databases or applications while increasing I/O throughput. End-users and IT staff will notice faster database access, much improved response times and faster batch processing.

"IT managers have long since accepted the fact that solid state storage technology offers one of the best returns in terms of throughput and latency over any other type of secondary storage. However, determining optimum SSD capacity and which hot files had to be relocated used to be an involved and hit-and-miss exercise. With the advent of E-Disk SafeCapacity, BiTMICRO's customers will now be able to unlock the potential of deploying E-Disk SSD through a systematic and best-practices approach to attaining a well-balanced storage architecture," says Rudy Bruce, President of BiTMICRO Networks. ...BiTMICRO Networks profile

Editor's comments:- in a nibble last year I commented that the SSD market was challenged by a lack of software tools which could automate their successful integration without specialist skills. In May this year Imperial Technology released two software products, WhatsHot and Serv2Stor, to deal with this issue. Today's news from BiTMICRO confirms this encouraging new trend to help users get the benefits from SSDs without having to become storage Einsteins.



Texas Memory Systems Launches World's Fastest External RAID Cache

Houston, Texas - July 29, 2003 - Texas Memory Systems, Inc. released today the RamSan-330 external storage cache.

The RamSan-330 turbo charges storage by caching the most popular data and distributing it at maximum rates of 3 gigabytes per second bandwidth and 250,000 I/Os a second.
While 16 gigabytes of RAID cache was once an expensive luxury to data centers, the RamSan-330's 16 to 64 gigabytes of fast RAID cache makes it available to any IT storage environment. By installing the RamSan-330 in front of RAID devices, bandwidth increases and response time decreases. Texas Memory Systems Launches Fastest RAID Cache Ever
The RamSan-330's four to eight 2Gbps Fibre Channel ports can be flexibly allocated to servers, switches or storage products. This means that a single RamSan-330 can simultaneously serve as a cache for multiple Fibre Channel RAID, JBOD or other storage devices. Storage vendors and solution providers have struggled to meet the needs of end users with increasingly demanding application environments, such as large, write-intensive databases. The RamSan-330 provides the solution by invisibly accelerating storage to the speed of SDRAM.

End users can use the RamSan-330 to overcome the costly bottlenecks associated with slow read/write performance across a large segment of data. It can accelerate existing storage 250 times by providing up to 250,000 IOPS and 3 gigabytes per second performance from cache. This translates into a 2x to 25x real performance improvement for applications.

The RamSan-330 is transparent to the operating system. It automatically caches frequently accessed blocks in its high-performance memory subsystem, improving read and write performance. Three cache modes are available for each cached storage device: write-through, write back, and read-ahead. The RamSan-330 delivers 3 gigabytes per second full duplex internal bandwidth. The system is battery-backed and will flush cache on external power failure simultaneously to the cached external storage devices and to internal hard disk drives. The system includes hot swap power supplies, hot swap backup hard disk drives, redundant fans and redundant batteries.

The Texas Memory Systems RamSan-330 is immediately available to storage manufacturers and solution providers worldwide. Pricing starts at $46k for a system which includes 4 x 2Gbps Fibre Channel ports in addition to the full suite of TMS cache software. ...Texas Memory Systems profile

STORAGEsearch.com publishes - Solid State Disks Buyers Guide

Editor:- July 28, 2003 - STORAGEsearch.com today published its Solid State Disks Buyers Guide which surveys products and prices in the range from $50 upto $2 million.

Solid State Disks were the #1 most popular subject accessed by STORAGEsearch readers in Q2 2003. But it's only recently that prices have dropped to the level where they can fit into the budget for most users. Most of the suppliers already in the market are specialist SSD companies, and therefore unknown to users who have never bought these products or systems before. So who do you choose? And how do you save time researching possible suppliers?

One way - is price... I contacted every manufacturer of SSDs in June to get contributions for this article - which is based on inputs received by our publication date. It's organised into 3 main price bands, with lowest cost at the top. Just scroll down the article until you see a budget, technology or application which best matches your situation. ...read the article

Nibble Re: Solid State Disks

Solid state disks look and behave similarly to conventional winchester hard disks. The access times are much faster, (microseconds rather than milliseconds) but the cost per gigabyte is very much higher. SSDs employ two main technologies:-
  • battery backed RAM - mainly used for performance acceleration, and
  • flash memory - mainly used for implementing hard disk emulation in military and industrial environments in which the weight and extra space taken by battery backup is not a feasible option. The simpler hardware in flash systems provides greater reliability, but there is a "wear out" factor related to the number of write cycles which makes it unsuitable for some applications.
There's a gray area in between where the newer generation of flash disks can be used to provide performance speedups in commercial server applications. However, the RAM based solutions are nearly always faster.

Solid State Disks... How Fast is Fast?

The world's fastest storage currently clocks in at 750,000 IOPS and it's made by Texas Memory Systems. But as with cars, high performance comes at a high cost, and the fastest is rarely going to be the most cost effective solution. Texas Memory Systems' own bread and butter product is their (slower) 250,000 IOPS system. There's a wide range of speed options available from competing vendors at different price points to suit different applications budgets.

But even a 50,000 IOPS SSD can still give you a two to three times speedup compared to hard drives in RAID systems on choked storage networks. So speed, price, ease of integration and expandibility are all factors you have to look at, just like as with other parts of your IT infrastructure.

Another Nibble Re: Solid State Disks

What can you do to make your system run faster when you're already using the fastest processors, have filled all your memory slots, and tuned up your application software?

SSD's were originally designed in the 1980's for use in real-time industrial and military systems, where they not only provided a performance boost, but also greater reliability because their solid state construction provided immunity against shock, vibration, dust and temperature extremes which could destroy conventional disk drives which use rotating magnetic media.

The main attraction of SSD's today is that they have an access time which is typically 200 times faster than the fastest hard drives. When used correctly in large database systems SSD's can realistically double the total system response time. Some applications can run even faster, provided that the SSD is large enough to contain all the critical files which are constrained by disk access time.

Because SSDs are identical to conventional hard drives in their mechanical, interface and software properties, they are literally plug and play devices. They can be used in all the ways that you'd use a conventional winchester drive, such as RAID, SAN and NAS systems, and models are typically available with SCSI or fibre-channel native interfaces.

When using an SSD, make sure you are using the fastest SCSI or FC adapter available for your system to get the most benefit. Your vendor should be able to advise you on this.

SSDs will only help you when your main constraint is access time. If your main system constraint is data throughput, as for example in streaming video applications, then almost any well designed RAID system based on conventional disks will give you fast enough performance and you may not need an SSD.

Benchmarking is the only way to be sure that an SSD will give you the performance boost you need, and that's when you sometimes discover that the real bottleneck is not what you originally thought.

Talk to the SSD vendor about your application. They're experts in the computer performance business. It's very likely that they've seen similar problems before and they may even be able to give you helpful hints about how to speed up other parts of your system.

Nibble:- Coming of Age for Solid State Disks

A
lthough manufacturers in the industrial controls market, like Square D and AB were using rewritable non volatile solid state storage as early as the 1970s, it wasn't till 1985 when Curtis introduced their ROMDISK for the original IBM PC, that the solid state disk market started in a form which we would recognise today. For most of its early life, this technology remained an open secret - mainly used in embedded systems in military applications, or in high performance computer research labs.

Now at 18 years old, the SSD market is ready to come out as a fully mature easy to use technology which will change the way in which all computer systems, from the desktop to the mainframe, are architected.

Here are some trends which track the interest of STORAGEsearch readers in the subject of SSDs over the past few years.

In Q1 2001 - SSDs were the 18th most popular subject.

In Q1 2002 - SSDs were #4.

In Q1 2003 - SSDs were #2.

In Q2 2003 - SSDs were #1. - (note added later July 2003)

That means there's more interest in SSDs in our readership than in NAS, or backup software, both subjects which attract hundreds of thousands of readers.

The reason is simple. The SSD market has the potential to become a bigger market than NAS and storage software are right now. In 2008 the SSD market will be worth more than $10 billion a year.

You, our readers, like to have a foretaste of emerging storage technologies. That's why many of the subjects on this website like iSCSI and Serial ATA shot into our top 5 most popular subjects more than a year before a single one of these products had ever been shipped.

SSD systems, if properly engineered, have the potential to replace dozens of processors in your most expensive mainframe, at a small fraction of the cost. At the low end, SSD software running on a desktop PC with a few hundred bucks of add in memory can outperform a $20K workstation in some critical business analysis applications.

That's why we researched and compiled the Solid State Disks Buyers Guide in July 2003 which collects together in one convenient document pricing information from across the whole SSD industry. It covers the range of budgets from under $50 up to $2 million and everything in between.

During this recession. many of the companies in the SSD market have been achieving double digit and triple digit revenue growth rates. But you'd be surprised how many of the leading companies in this market have been around for ten years or more, working quietly away at this technology. All that is going to change soon, and I have a feeling that some of them will become as well known in the general IT market place as VERITAS and Network Appliance are today.

And my ScryWare crystal ball to market report generator is seldom wrong...
