You dont have a millisecond to spare. No matter where you look, business is

moving aster. These days your customers expectand the market demandsnearly

instantaneous response.

Telecommunications companies serve customers who are accustomed to mobile services that are

always on and instantly available. Financial services organizations now live in a world o electronic

trading, where a hal-second advantage can mean millions o dollars in proit or loss.

Those are just two examples o the pressures that accelerating expectations are placing on

organizations everywhere. Staying competitive and delivering the highest quality o service in this

anywhere, anytime world requires real-time data access and continuous data availability.

Delivering those levels o perormance with traditional disk-based databases is extremely

challengingi not impossible. To meet their needs or extreme speed and extreme availability,

businesses are turning to in-memory databases. As the name implies, an in-memory database

resides entirely in main memory rather than on disk, making data access an order o magnitude

aster than with conventional, disk-based databases.

IBM solidDB is a relational, in-memory database known worldwide or delivering data with

extreme speed and extreme availability. With solidDB, organizations can achieve response times

measured in microseconds and levels o availability that surpass the well-known ive nines

standard. IBM solidDB delivers the velocity and reliability that you need to tackle the most

challenging environmentswhere microseconds matter.

In-memory database: low latency and high throughput

By storing all inormation in RAM, in-memory databases like solidDB start with a tremendous advantage

over traditional disk-based databases: RAM simply provides aster I/O access than hard disk drives.

But pure in-memory databases also outperorm disk-based databases that have been completely

cached in system memory. IBM solidDB uses data structures and access methods that are

speciically designed or storing, searching and processing data in RAM. Data access is optimized

because solidDB is designed to expect that data is in memory, which minimizes CPU usage

compared to disk access.

The result is thatas an in-memory databasesolidDB delivers very high transaction rates and

extremely low latency, a critical combination or achieving extreme speed. Many databases can

produce high aggregate transaction rates, but individual transactions still take tens or hundreds o

milliseconds to complete. Other databases can manage short response times (or low latency) or

individual transactions, but cannot handle large numbers o transactions or concurrent sessions.

IBM solidDB consistently provides throughput measured in the range o tens-to-hundreds o

thousands o transactions per second and consistently achieves response times (latencies)

measured in microseconds.

IBM solidDB

IBM solidDB delivers extreme speed and extreme availabilityThe heart o solidDB is an ACID (atomicity, consistency, isolation and durability) compliant relational,

in-memory database that persists data to disk and can stand alone as the database o record. You can

host all o your data in-memory or maximum speed, or you can host some or all o it in disk-based

tables also supported by solidDB. Applications can access both in-memory and disk-based tables

transparently, and use them in the same transactions. By dividing data between in-memory tables and

disk-based tables, you can achieve your ideal price/perormance ratio.

IBM solidDB can also be used as a high-speed cache (solidDB Universal Cache) to accelerate

access to data stored in other relational, disk-based databases, including IBM DB2, IBM

Inormix, Oracle database, Sybase or Microsot SQL Server. In this case, solidDB uses

high-perormance synchronization sotware to seamlessly transer data between the in-memory cache

and the disk-based database. IBM solidDB Universal Cache is highly adaptable to dierent application

and deployment needs, and can be deployed as a read-only cache or as a read-write cache.

In either case, solidDB uses the amiliar SQL language and in-memory technology to accelerate

OLTP workloads and perorm up to ten times aster than conventional, disk-based databases.

IBM solidDB also delivers extreme data availability. The traditional benchmark o ive nines

(99.999 percent uptime) translates to 5 minutes and 15 seconds o downtime per year. But with solidDB,

you can achieve up to six nines o availability: 99.9999 percent uptime, or less than 32 seconds o

downtime per year. In act, long-term solidDB customers have reported 100 percent data availability

over the course o several years.

Using a two-node, hot-standby coniguration, solidDB maintains two copies o data synchronized

between two solidDB instances. In case o a system ailure, transparent ailover rom the active node

to the hot-standby node can occur in less than a second. The secondary instance takes over the

processing load instantly, preventing data loss.

IBM solidDB also helps ensure recoverability by writing a transaction log. This, combined with a lexible

checkpoint operation (saving o the memory image to disk, which does not interere with or slow down

database operation), helps ensure that solidDB is just as recoverable as a disk-based databasebut

with the speed and high availability needed to power todays real-time applications.

Extreme speed and availability in the real world

Financial services

In inancial services, brokerage applications receive market eeds, evaluate equity positions, execute

trades and check or raud. Those applications can evaluate, or example, more than 30,000 rules

on 500 trades per second or 15 million trades per day. And time is o the essence. A delay o even

a millisecond or two between retrieving the market price or a trade and making an oerperhaps

waiting or an I/O channel to clearcan be disastrous.

Bolsa de Comercio (the Chilean Stock Exchange), based in Santiago, Chile, deployed solidDB

Universal Cache as a ront-end to Microsot SQL Server, enabling them to respond to peak work-

loads o more than 30,000 messages per second, completing each in microseconds. And thats

just the beginning, as the inancial services company also needed to help ensure continual data

availability to meet very strict service-level agreements (SLAs).

Telecommunications

Telecommunications companies use online charging systems to authenticate and authorize network

usage, initiate service, manage credit balances and more, all in real time or millions o concurrent

users (mobile phone subscribers). Those applications require access to data in tens o microseconds

instead o the milliseconds experienced with traditional relational databases. Slow or inconsistent

response times can negatively impact customer service levels and customer satisaction.

China EB, an intelligent networking solutions and telecommunications provider in Beijing, implemented

solidDB Universal Cache to address the problem o its increasing number o subscribers expecting

real-time service, while keeping its investment in IBM Inormix sotware which continues to work well

or a variety o workloads.

By implementing solidDBUniversal Cache as a

ront-end to Inormix

able to meet our low-

latency demands or

very heavy, real-time

workloads, keeping datasynchronized between

Inormix and solidDB

Cost benefits

Its not oten that you get aster speeds and lower costs, but solidDB oers just that. To begin

with, the extreme speed and extreme availability provided by solidDB helps you keep data always

accessible, so that you can avoid the costs associated with outages and delays. You can also

dramatically increase the transaction rate and throughput o applications without upgrading your

database server. And, o course, increased throughput can mean more revenue by allowing you

to process more transactions.

With solidDB, you can postponeor even avoidcostly hardware upgrades associated with

perormance bottlenecks in the application tier. IBM solidDB can run on commodity, as well as

best-o-breed hardware, giving you lots o options to build a proven, cost-eective solution. Once

its up and running, solidDB also helps keep maintenance costs low because it can be controlled

by the application and run virtually unattended.

IBM solidDB also helps lower adoption costs. It is based on SQL-compliant relational database

technology, so you can leverage existing expertise and investments in relational database

technology. Remember, solidDB Universal Cache works with almost any commercial relational

database.

Todays per ormance-critical applications demand more stringent SLAs. IBM solidDB can help

you meet perormance SLAs by achieving hundreds o thousands o transactions per second with

response times measured in microseconds. Using a two-node, hot-standby coniguration, it can

help you meet availability SLAs as well.

At the end o the day, greater speeds and higher availability means improved customer satisaction.

With solidDB, businesses can leverage new applications to dierentiate themselves by accommodating

increased workloads or a greater number o users while oering new services in real time.
