WikitipDemartek Publishes SSD PrimerBecause of the great interest in solid state storage (SSS) technology, we have compiled this summary document providing some basic information for solid state drive (SSD) or solid state disk technology. The terms SSS and SSD are often used interchangeably. Technically, SSD refers to a specific form factor, while SSS refers to any solid state storage form factor. Solid state storage devices are computer storage devices that use memory technology for the storage media rather than traditional magnetic media such as hard disk drives (HDD) or tape drives. These SSS devices can be made with DRAM memory technology or Flash memory technology, or sometimes both. These devices appear to the host operating system as storage devices. This document will be updated periodically and may become larger over time. Contact us if you’d like to see additional information in this document. This documents includes acronyms, discussion of form factors, NAND flash basics, endurance, performance, cost metrics and data placement strategies such as caching and tiering. This primer is available on the Demartek web site. |
Featured Case Study
Virtualization Energizes Cal State UniversityJohn Charles is the CIO of California State University, East Bay (CSUEB) and Rich Avila is Director, Server & Network Operations. In late 2007 they were both looking down the barrel of a gun. The total amount of power being used in the data center was 67KVA. The maximum power from the current plant was 75kVA. PG&E had informed them that no more power could be delivered. They would be out of power in less than six months. A new data center was planned, but would not be available for two years. |

Featured How-To Note |
Storage Virtualization Design and DeploymentA main impediment to storage virtualization is the lack of multiple storage vendor (heterogeneous) support within available virtualization technologies. This inhibits deployment across a data center. The only practical approach is either to implement a single vendor solution across the whole of the data center (practical only for small and some medium size data centers) or to implement virtualization in one or more of the largest storage pools within a data center. | |||
