QU\u00c8 \u00c9S UN RAID?<\/h2>\n\n\n
\n
\"\"<\/figure>\n<\/div>\n\n\n

RAID ve de les sigles de les paraules en angl\u00e8s Redundant Array of Inexpensive Disks i \u00e9s una tecnologia \u00e0mpliament utilitzada.<\/p>\n\n\n\n

El RAID \u00e9s la manera com l\u00f2gicament es formen junts en una sola matriu. La idea aleshores \u00e9s que aquests discos treballant junts tinguin la velocitat i la confian\u00e7a d'un disc m\u00e9s cost\u00f3s. Encara que el RAID \u00e9s una excel\u00b7lent soluci\u00f3, la velocitat i confiabilitat exactes que obtindr\u00e0 del RAID dep\u00e8n del tipus que utilitzeu.<\/p>\n\n\n\n

Els discos giratoris, els discs durs mec\u00e0nics o els discs de disc dur (HDD) s'escullen normalment en situacions en qu\u00e8 necessitats com la velocitat i el rendiment cauen en segon lloc pel que fa al cost. A causa de les limitacions f\u00edsiques i la naturalesa mec\u00e0nica de moltes parts m\u00f2bils, els HDD tenen una taxa de falles relativament alta. Davant d'aix\u00f2, els RAID estan destinats a ajudar a alleujar aquests problemes.<\/p>\n\n\n\n

Hi ha diferents tipus de RAID, per exemple, el RAID 0, que pren qualsevol quantitat de discos i els fusiona en un gran volum. Aix\u00f2 augmentar\u00e0 considerablement la velocitat, ja que llegeix i escriu des de diversos discos alhora. No obstant aix\u00f2, el desavantatge de RAID 0 \u00e9s que no \u00e9s redundant. La p\u00e8rdua de qualsevol disc individual provocar\u00e0 una p\u00e8rdua total de dades. Per aix\u00f2, aquest tipus de RAID \u00e9s molt menys fiable. El RAID 0 pot utilitzar-lo per a mem\u00f2ria cau o altres prop\u00f2sits on la velocitat \u00e9s important i la p\u00e8rdua de dades no importa en absolut.<\/p>\n\n\n\n

Per altra banda, tenim el RAID 1, amb una configuraci\u00f3 molt m\u00e9s complicada. El RAID 1 t\u00e9 un parell de discos id\u00e8ntics que dupliquen o copien les dades per igual a totes les unitats de la matriu. Aix\u00f2 genera que si es perd completament una unitat es pot seguir funcionant amb una unitat addicional. En cas que alguna de les unitats falli, podeu reempla\u00e7ar la unitat trencada amb poc o cap temps d'inactivitat. Tamb\u00e9 us brinda el benefici addicional d'un major rendiment de lectura, ja que les dades es poden llegir en qualsevol de les unitats de la matriu. Els desavantatges s\u00f3n que tindr\u00e0 una lat\u00e8ncia d'escriptura lleugerament m\u00e9s gran. Com que les dades s'han d'escriure a les dues unitats de la matriu, nom\u00e9s tindreu la capacitat disponible d'una sola unitat mentre necessiteu dues unitats.<\/p>\n\n\n\n

En canvi, el RAID 5 requereix l'\u00fas d'almenys 3 unitats i el que fa \u00e9s prendre la idea de RAID 0 i eliminar les dades a diverses unitats per augmentar el rendiment. Per\u00f2 tamb\u00e9 afegeix l'aspecte de la redund\u00e0ncia en distribuir informaci\u00f3 de paritat entre els discos. Aix\u00f2 vol dir que un RAID 5 pot perdre un disc i tot i aix\u00ed mantenir les operacions i dades. Aix\u00f2 es tradueix en un rendiment de lectura significativament millorat, per\u00f2 el rendiment d'escriptura dep\u00e8n molt del controlador RAID utilitzat.<\/p>","protected":false},"excerpt":{"rendered":"
