O Desafio… Growing Need For Networked Storage Aumento o uso os dados – Novos aplicativos necessitam cada vez mais de storage Aumento de informações on-line As capacidades Online continuam a crescer a taxas de 100% ao ano Aumento do custo do gerenciamento de Storage O custo de gerenciamento contra o custo do hardware está em 5:1 Aumento do impacto de performance Serviços de aplicação e file services rodando na mesma plataforma In today’s corporate environment, there are many things driving the necessity for networked storage. There are ever increasing uses for existing data, such as data mining, data warehousing and e-commerce. [click next] There is ever increasing need to have large amounts of on-line information available. Current projections show online data capacities to be growing 100% annually. [click next] Storage management is becoming is also increasing. Management costs currently outweigh hardware purchase price by a factor of 5:1. [click next] With all of this increased activity the result is an impact on performance. The performance of application servers are being severely impacted when also being used to provide file services. [click next]

Direct Attach Storage (DAS) Dificuldade para gerenciar Requer alto nível de conhecimento em gerenciar e manter Client LAN Application/File Server Disk Array Dificuldade em Escalar Client Application/File Server Tape Library Alto custo de TCO The topology shown here demonstrates a fairly typical Direct Attached Storage Configuration. When there is a need for more storage, an administrator simply adds more disks or another external storage subsystem to an existing file server. There are some inherited problems with this older method of storage being used to deliver networked file services. [click next] It’s difficult to manage direct attached storage configurations and generally requires a high degree of skill to manage and maintain. [click next] It’s also very difficult to scale. Adding disk capacity can take hours and could also effect end user file service availability. [click next] When file services are being provided on a server that is also being used as an application server there is resource contention between compute tasks and I/O tasks. [click next] All of these factors lead to a very high total cost of ownership. [click next] Client Application/File Server Optical Storage

Benefícios da Topologia NAS O NAS é conectado diretamente na rede (LAN) e prporciona recursos de storage para todos os usuários da rede NAS File Server Client LAN O NAS foi desenvolvido para ser fácil de instalar, robusto ideal para ambientes departamentais e enterprise.

Client A NAS server attaches to an existing LAN and provides storage resource to all users on the network. NAS servers are designed to provide hassle-free, reliable storage expansion for small offices, workgroups, and departmental class networks. The inherrited attributes of NAS servers are a better value to the customers than the Direct Attached Storage model. [click next] NAS servers are easy to install and only take minutes to setup and configure for immediate use. [click next] Very low to no technical skills are reguired to manage and maintain a NAS server. [click next] The basic principals of NAS are based on mature networking and storage technologies. [click next] All of these things add up to a much lower cost of ownership. [click next] Baixo TCO

NAS é a Solução!! Movimenta os dados mais perto dos usuários Performance optimized for file services Suporte a ambiente heterogêneo (Windows, UNIX, Linux e Apple) Simples de gerenciar e manter – Baixo nível de conhecimento técnico The attributes of NAS servers provide very robust and flexible storage solutions. In larger networks with departmental subnets or remote offices, NAS servers can move data closer to the user. By installing a NAS server in the same LAN as the user, access performance will be increased dramatically. [click next] Since a NAS servers are designed specifically for networked file services performance is optimized for file services as opposed to how general purpose servers are optimized. [click next] With no special software to install, NAS servers can support all major file access methods, such as Windows, UNIX, Novell and Apple. [click next] As mentioned earlier, since NAS servers are simple to manage and maintain with little to no special skills required it is an attractive solution for all IT organizations. [click next] With simplified setup and administration, NAS servers lower the Total Cost of Ownership and thus, become the preferred choice as the most cost effective storage solution.

The most common problems are storage, network saturation, and CPU saturation. Traditional solutions include more powerful CPUs or server attached storage and faster networks. Because you can only plug so much storage behind a processor before saturating it, storage has been dictating the need for servers. [click next] As the networks get larger and more complex additional problems arise. [click next] These include: Traffic imbalance caused by large files such as engineering CAD files or marketing presentations with audio/video files. Multiple client environments (i.e.UNIX & NT on same network) creating separate resource allocations issues. Complex installation and management. Larger networks are dynamic entities with administration personnel constantly balancing resources. Daily hardware changes are not uncommon. And of course insufficient backup windows as online storage resources swell to meet user requirements. [click next] Traditional solutions include: Adding Ethernet switches to prioritize traffic conflicts, but these cannot cure saturated networks. Many companies are installing gigabit or fibre backbones or even entire gigabit or fibre networks to speed traffic along. Occasionally administrators install remote servers to localize network traffic Some administrators distribute storage, storage I/O and backup between many individual servers to facilitate faster data access and complete backups. In some cases companies are satisfied with partial or weekly backups Data Server Redes Mais Rápidas Servidores Remotos com Storage Servidores dedicados para I/O com tape drivers individuais Backups Parciais e Semanais Remote Server

Como o NAS resolve estes problemas? NAS para File Services e Servidores para Aplicações Benefícios Conexão direta a rede utilizando Hub, Switch ou Router. Remove o fluxo I/O dos servidores de aplicação, aumentando a potencialidade destes servidores Ganhos significativos em storage e também em fluxo de dados I/O (mais performance) Trafego de rede localizado Gerenciamento facilitado, Local ou Remoto Instalação em menos de 10 minutos Não necessita de licenças Escalabilidade em performance e capacidade Acesso compartilhado Windows, UNIX, e Apple Storage de Alta Disponibilidade Marketing Audio Video files Database management Presentations Graphic files NT Server NAS File Server NAS File Server Ethernet Switch UNIX Server There are many benefits for using NAS servers to solve your most critical network and storage issues. [click next] NAS servers plug in just as any other workstation or server to a port on your network. Some NAS servers have optional support for different network architectures such as gigabit or fibre-channel and some are field upgradeable offering investment protection as businesses needs change. Buy removing data I/O from application servers you save money by extending the useful life of existing servers. Data I/O is improved because NAS servers use a thin operating system. Operating Systems like NT or UNIX are designed to accommodate all peripheral devices or programs that could be installed on a server. NAS operating system only have to account for a fixed set of devices and programs making them very small and very efficient for file services. Since NAS servers have IP addresses you can physically located the unit at an individual workstation or within a group and traffic remains local to that individual or group. Most NAS servers have been designed specifically for either local or remote management. Good NAS servers are designed as appliances and can be installed very quickly without interruption of service. They can also be redeployed with the same effort should you need to physically reallocate resources. Most NAS boxes do not require seat license or server O/S licenses. Other features to look for are scalability, multiple platform support and high availability. NAS File Server Engineering CAD files Software programs Modeling data Scientific data
