Zida Zosungirako, Disk Arrays ndi Storage Systems, SAN, NAS

 

STORAGE DEVICE kapena imadziwikanso kuti STORAGE MEDIUM ndi zida zilizonse zamakompyuta zomwe zimagwiritsidwa ntchito kusunga, kunyamula ndi kuchotsa mafayilo ndi zinthu. Zipangizo zosungira zimatha kusunga ndi kusunga zidziwitso kwakanthawi komanso mpaka kalekale. Zitha kukhala mkati kapena kunja kwa kompyuta, ku seva kapena ku chipangizo chilichonse chofananira.

 

 

Cholinga chathu ndi DISK ARRAY chomwe ndi chinthu cha hardware chomwe chili ndi gulu lalikulu la hard disk drives (HDDs). Ma disk arrarays amatha kukhala ndi ma tray angapo a disk drive ndipo amakhala ndi zomanga zomwe zimathandizira kuthamanga ndikuwonjezera chitetezo cha data. Woyang'anira yosungirako amayendetsa dongosolo, lomwe limagwirizanitsa ntchito mkati mwa unit. Ma Disk arrays ndiye msana wa malo ochezera amakono osungira. Ma disk array ndi DISK STORAGE SYSTEM yomwe imakhala ndi ma drive angapo a disk ndipo imasiyanitsidwa ndi diski yotsekera, chifukwa gululi lili ndi kukumbukira kwa cache ndi magwiridwe antchito apamwamba monga RAID ndi virtualization. RAID imayimira Redundant Array of Inexpensive (kapena Independent) Disks ndipo amagwiritsa ntchito ma drive awiri kapena kuposerapo kuti apititse patsogolo magwiridwe antchito komanso kulolerana ndi zolakwika. RAID imathandizira kusungidwa kwa data m'malo angapo kuti iteteze deta ku katangale ndikuipereka kwa ogwiritsa ntchito mwachangu.

 

 

Zigawo zamitundu yofananira ya disk ndi:

 

Ma Disk array controller

 

Cache kukumbukira

 

Zojambula za Disk

 

Zida zamagetsi

 

 

Nthawi zambiri ma disk arrays amapereka kuchuluka kwa kupezeka, kulimba mtima ndi kusamalitsa pogwiritsa ntchito zida zowonjezera, zosafunikira monga zowongolera, zida zamagetsi, mafani, ndi zina zambiri, mpaka pomwe mfundo zonse zolephera zimachotsedwa pamapangidwewo. Zigawozi nthawi zambiri zimakhala zotentha.

 

 

Kawirikawiri, ma disk arrays amagawidwa m'magulu:

 

 

NETWORK ATTACHED STORAGE (NAS) ARRAYS : NAS ndi chida chosungira mafayilo chomwe chimapatsa ogwiritsa ntchito ma network amderali (LAN) okhala ndi malo apakati, ophatikizidwa a disk kudzera pa intaneti yokhazikika ya Ethernet. Chipangizo chilichonse cha NAS chimalumikizidwa ndi LAN ngati chida chodziyimira payokha ndipo chimapatsidwa adilesi ya IP. Ubwino wake waukulu ndikuti kusungirako maukonde sikungokhala kusungirako kwa chipangizo cha kompyuta kapena kuchuluka kwa ma disks mu seva yakomweko. Zogulitsa za NAS zimatha kukhala ndi ma disks okwanira kuti athandizire RAID, ndipo zida zingapo za NAS zitha kulumikizidwa pa netiweki kuti zikulitse zosungira.

 

 

STORAGE AREA NETWORK (SAN) ARRAYS : Zili ndi disk imodzi kapena zingapo zomwe zimagwira ntchito ngati nkhokwe ya deta yomwe imasunthidwa ndi kutuluka mu SAN. Zosungirako zosungira zimalumikizana ndi nsalu ndi zingwe zomwe zikuyenda kuchokera pazida zomwe zili munsanjika ya nsalu kupita ku ma GBIC omwe ali pamadoko pagulu. Pali makamaka mitundu iwiri ya ma netiweki osungira, omwe ndi ma modular SAN arrays ndi monolithic SAN arrays. Onsewa amagwiritsa ntchito kukumbukira kwamakompyuta omangika kuti afulumizitse komanso kusungitsa mwayi wofikira pang'onopang'ono disk. Mitundu iwiriyi imagwiritsa ntchito posungira kukumbukira mosiyana. Ma monolithic arrays nthawi zambiri amakhala ndi ma cache memory ochulukirapo poyerekeza ndi ma modular array.

 

 

1.) ZOTHANDIZA SAN ARRAYS : Awa ali ndi ma doko ochepa, amasunga deta yocheperapo ndikugwirizanitsa ndi ma seva ochepa poyerekeza ndi ma SAN arrays a monolithic. Amapangitsa kuti wogwiritsa ntchito monga makampani ang'onoang'ono ayambe pang'ono ndi ma drive ochepa a disk ndikuwonjezera chiwerengero pamene zosowa zosungira zikukula. Amakhala ndi mashelufu osungira ma disk. Ngati alumikizidwa ndi ma seva ochepa, ma modular SAN arrays amatha kukhala othamanga kwambiri ndikupatsa makampani kusinthasintha. Ma modular SAN arracks amakwanira muzitsulo zokhazikika za 19 ”. Nthawi zambiri amagwiritsa ntchito owongolera awiri okhala ndi kukumbukira kosungirako kosiyana mumtundu uliwonse ndikuwonetsa posungira pakati pa owongolera kuti aletse kutayika kwa data.

 

 

2.) MONOLITHIC SAN ARRAYS : Awa ndi magulu akuluakulu a disk drives mu data center. Amatha kusunga zambiri poyerekeza ndi ma modular SAN arrays ndipo nthawi zambiri amalumikizana ndi mainframes. Ma Monolithic SAN arrays ali ndi olamulira ambiri omwe amatha kugawana nawo mwayi wofikira ku cache yofulumira yapadziko lonse lapansi. Ma monolithic arrays nthawi zambiri amakhala ndi madoko ochulukirapo kuti alumikizane ndi ma network osungira. Chifukwa chake ma seva ambiri amatha kugwiritsa ntchito gululi. Nthawi zambiri ma monolithic arrays ndi ofunikira kwambiri ndipo amakhala ndi kusinthika kwapang'onopang'ono komanso kudalirika.

 

 

ZOSAVUTA ZOSANGALALA ZOTHANDIZA : Muchitsanzo chosungirako zinthu zogwiritsira ntchito, wothandizira amapereka mphamvu zosungirako anthu kapena mabungwe pamalipiro ogwiritsira ntchito. Mtundu uwu wautumiki umatchedwanso kusungirako pakufunika. Izi zimathandizira kugwiritsa ntchito bwino zinthu komanso kuchepetsa mtengo. Izi zitha kukhala zotsika mtengo kwamakampani pochotsa kufunika kogula, kuyang'anira ndi kukonza zida zomwe zimakwaniritsa zofunikira zomwe zitha kupitilira malire ofunikira.

 

 

STORAGE VIRTUALIZATION : Izi zimagwiritsa ntchito virtualization kuti zitheke kugwira ntchito bwino komanso zapamwamba kwambiri pamakina osungira ma data apakompyuta. Kusungidwa kosungirako ndiko kusanjikiza kowonekera kwa deta kuchokera kumitundu ingapo kapena mitundu yosiyanasiyana ya zosungira kukhala zomwe zimawoneka ngati chipangizo chimodzi choyendetsedwa ndi kontrakitala yapakati. Zimathandizira oyang'anira zosungirako zosunga zobwezeretsera, kusungitsa ndi kuchira mosavuta komanso mwachangu pothana ndi zovuta za network yosungirako (SAN). Izi zitha kutheka pokhazikitsa virtualization ndi mapulogalamu apulogalamu kapena kugwiritsa ntchito zida za Hardware ndi mapulogalamu a hybrid.
