Solid State Disk
Nutzen und Vorteile einer Solid State Disk
"Konventionelle Speichersysteme basieren auf Magnetplattentechnologie, bei der mechanische Komponenten
die gewünschten Daten „physikalisch“ suchen und bereitstellen. Dieser mechanische Weg Informationen
auszuwerten ist das schwächste Glied in der Eingabe- /Ausgabekette von Datenbank und Informationssystemen.
Typische Wartezeiten – zwischen Datenanfrage und Datenempfang – liegen selbst bei den besten RAID Festplatten-Systemen im Bereich 5-6 Millisekunden. Auf einem RamSan-300 und dem RamSan-400 Solid State Speichersystem werden Daten nicht auf traditioneller Festplatte gespeichert, sondern
auf DDR-RAM Speicherbausteinen. Die Wartezeit wird damit auf 14 Mikrosekunden verringert – 250 x schneller als herkömmliche Festplatten-RAID Systeme. Bei einer RamSan-500 mit gepuffertem Flash-Speicher beträgt die Antwortzeit nur 200 Mikrosekunden und ist somit 20x schneller als RAID... mehr" |

Solid State Disk
Flash in the Enterprise
"Flash memory is poised to become a major player in datacenter storage systems. It
provides an all electronic method of storing data in silicon, removing the only
component in modern data processing systems that still relies on moving parts in the
data path: the spinning hard disk. Though Flash memory offers some compelling
advantages over disk-based storage, it is not well understood in the storage industry.
This paper describes some the properties of Flash memory and then explains how the
RamSan-500, produced by Texas Memory Systems, leverages its strengths and
compensates for its weaknesses to offer the first enterprise ready Flash system... mehr" |

Faster Oracle Performance with Solid State Disk
"This whitepaper discusses methods for improving Oracle database
performance using solid state disks to accelerate the most resource‐intensive data
that slows performance across the board.
To this end, it discusses methods for identifying I/O performance
bottlenecks, and it points out components that are the best candidates for
migration to a solid state disk. An in‐depth explanation of solid state disk
technology and possible implementations are also included... mehr" |

Solid State Disk
An In-depth Look at the
RamSan-500 Cached Flash
Solid State Disk
"The RamSan-500, produced by Texas Memory Systems (TMS) is the world’s first
cached Flash solid-state disk (SSD) designed from the chip up to meet enterprise
requirements for performance, scalability, and reliability. The RamSan-500 is a
fusion of DDR and Flash memory. The system takes advantage of the strengths
of each technology:
• Blazing fast write performance (DDR)
• Fast reads (Flash)
• High density (Flash)
• Low power consumption (Flash)
• Lower cost per capacity (Flash)... mehr" |

Solid State Disk
An In-depth Look at the
RamSan-400 Solid State Disk
"Accelerate OLTP, batch processing and other intense applications with the
RamSan solid state disk from Texas Memory Systems—the only solid state disk
available with the performance, software, and features that critical enterprise
applications demand. It is 2x‐10x faster than cache included in popular RAID
storage systems, yet it also contains the most high‐availability features in the
solid state disk industry and fits the most GB of RAM storage per rack unit. The
RamSan is the only solid state disk that allows users two distinct modes of data
retention, customizable for each LUN on the unit. Placing hot data on a RamSan
allows maximum return on existing critical applications and hardware... mehr" |

Solid State Disk
An In-depth Look at the RamSan-300 Solid State Disk
"Texas Memory Systems developed the RamSan‐300 with one idea in mind: to deliver an enterprise solid state disk with entry‐level pricing. The RamSan‐300 meets these objectives by inheriting most of its components from the RamSan‐400 enterprise solid state disk. The RamSan‐300 uses the same memory boards, Fibre Channel controllers, batteries, fans, power suppliers, and backup hard disk drives as the industry leading RamSan‐400... mehr" |

Solving the Energy Crisis in the
Data Center Using COPAN Systems’
Enhanced MAID Storage Platform
" Energy consumption for storage in the data center is becoming a paramount concern for
everyone in the IT industry – from CIOs to technology managers. The increasing volume
of spinning disks is creating a large and growing energy crisis. Traditional approaches to
reducing energy requirements for data storage, such as replacing lower capacity drives
with higher capacity drives, is merely an interim step that only provides incremental,
short-term relief. However, these approaches actually do very little to address the overall
issue of storage-related power consumption in the data center... mehr"
