Q195840 | Redes de Computadores, SAN, Analista, INFRAERO, FCC

A blade is literally a self-contained server, which collectively fits into an enclosure with other blades. Sometimes known as a chassis, this enclosure provides the power, cooling, connectivity, and management to each blade. The blade servers themselves contain only the core processing elements, making them hot-swappable. A single blade contains hot-plug hard-drives, multiple I/O cards, memory, multi-function network interconnects, and Integrated Lights Out remote management. For additional storage, blades can connect to another storage blade or to a network attached SAN.
Com base no texto acima, é correto afirmar que blades

a) são literalmente servidores interdependentes.
b) compartilham energia, refrigeração e conectividade oferecida pelo gabinete.
c) utilizam os mesmos cartões de E/S, memória e interconectores de rede.
d) podem ser conectados apenas em blade de armazenamento do tipo SAN.
e) podem ser trocados individualmente com o sistema em operação, se tiverem apenas elementos de processamento central.
