Uporabnost SSD-jev v skladi\u0161\u010denju podatkov \u017ee ne presene\u010da nikogar. SSD-ji so trdno zakoreninjeni v IT opremi, od osebnih ra\u010dunalnikov in prenosnikov do stre\u017enikov in sistemov za shranjevanje podatkov. V tem \u010dasu se je zamenjalo ve\u010d generacij SSD-jev, vsaka od katerih je imela izbolj\u0161ane zna\u010dilnosti glede zmogljivosti, zanesljivosti in najve\u010dje kapacitete. Vpra\u0161anje spremljanja zapisa SSD-jega vira pa ostaja aktualno.<\/p>\n

<\/p>\n

\"Spremljanje
\n<\/a><\/noindex><\/p>\n

SSD-ji imajo zaradi svoje fizi\u010dne zasnove vnaprej omejen vir zapisovanja. Dejstvo, da se na SSD dejansko zapi\u0161e bistveno ve\u010d podatkov, kot jih po\u0161lje gostitelj (zlasti kot del RAID skupine), \u0161e bolj pribli\u017ea k ozna\u010denemu limitu. To je za nekatere uporabnike nekak\u0161na skrb pred uporabo SSD-jev.<\/p>\n

<\/p>\n

Dejansko pa ni vse tako slabo. Ocenjeni vir DWPD je naveden za celotno garancijsko dobo diska (obi\u010dajno 3-5 let). Zato bo dejanski vir zapisovanja TBW precej impresiven, kar omogo\u010da, da se ne bojite \u201eizbrisati\u201c SSD v le nekaj mesecih. Poleg tega je v nekaterih primerih mogo\u010de za\u010dasno uporabljati diske v bolj intenzivnem na\u010dinu, kot ga predvideva proizvajalec, prav zaradi visokih vrednosti TBW. Vse to pa nikakor ne odpravlja potrebe po spremljanju trenutnega vira zapisovanja vsakokratnega SSD-ja z namenom proaktivne zamenjave ob doseganju dolo\u010denih pragov.<\/p>\n

<\/p>\n

Vsak ponudnik SCSI diskov na svoj na\u010din implementira to funkcionalnost. A najpogosteje gre preprosto za lastnost diska, deluje\/ne deluje. Qsan<\/a><\/noindex> v svojih sistemih All Flash<\/a><\/noindex>, nasprotno, je omogo\u010dil popolno vizualizacijo parametrov trenutne aktivnosti SSD-jev v obliki lo\u010denega modula z imenom QSLife. Ta modul je nepogre\u0161ljiv del nove operacijske sistema XEVO<\/a><\/noindex>, pod katerim bodo v prihodnosti delovali vsi SCSI diski Qsan.<\/p>\n

<\/p>\n

Za vsak SSD v sistemu se v najve\u010dji mo\u017eni meri prikazuje trenutna \"stopnja \u017eivljenja\". Ni skrivnost, da vsi sodobni SSD-ji sami bele\u017eijo zapisane bloke. Na podlagi teh vrednosti sistem izra\u010duna stopnjo obrabe pomnilnika glede na njegovo razporeditev. Kon\u010dni rezultat se prika\u017ee v odstotkih od vrednosti povsem novega SSD-ja. Prav tako naj poudarimo, da se stopnja obrabe ne izra\u010duna le za obdobje, v katerem je pomnilnik deloval v okviru All Flash sistema Qsan, temve\u010d za celotno njegovo \u017eivljenjsko dobo, vklju\u010dno z delovanjem v drugih sistemih (\u010de je bilo to slu\u010dajno).<\/p>\n

<\/p>\n

\"Spremljanje<\/p>\n

Poleg poenostavljenih informacij o pomnilniku se lahko izvejo tudi nekateri podrobnosti. Zlasti prostornina podatkov, zapisanih na njem skozi celotno \u017eivljenjsko dobo. In v \u010dasu, ko je pomnilnik deloval v okviru All Flash sistema Qsan<\/a><\/noindex>, so na voljo grafi njegovega delovanja v operacijah branja in pisanja. Statistika se zbira v realnem \u010dasu in je na voljo za katerokoli obdobje z globino pregledovanja do enega leta.<\/p>\n

<\/p>\n

\"Spremljanje<\/p>\n

Seveda je cilj te funkcionalnosti ne le ustvarjanje lepih grafov za zadovoljstvo administratorja, temve\u010d tudi proaktiven pregled stanja pomnilnikov in prepre\u010devanje potencialnih te\u017eav v prihodnosti, povezanih z njihovo obrabo. Zato se glede na \"stopnjo \u017eivljenja\" SSD-jev lahko nastavi mno\u017eica pragov in ustreznih dejanj, povezanih z iztro\u0161enjem zapisnega vira SSD.<\/p>\n

<\/p>\n

\"Spremljanje<\/p>\n

\u010ce pogledamo druge modele SAN (ne specializirane All Flash, temve\u010d splo\u0161ne namene) od Qsan<\/a><\/noindex>, pa ni takega vizualiziranega poro\u010dila o pomnilnikih. Kar je razumljivo: na koncu koncev mora biti zastopnik nekako druga\u010den od mainstreama. Kljub temu pa se v redni liniji izdelkov tak\u0161no spremljanje nujno izvaja. Da, brez zbiranja statistike o uporabi in zmogljivosti. Vendar je glavna funkcija spremljanja zapisnih virov prisotna.<\/p>\n

<\/p>\n

\"Spremljanje<\/p>\n

Zaradi nenehnega izbolj\u0161evanja tehnologij proizvodnje trdih diskov je vpra\u0161anje njihove zanesljivosti nekoliko utihnilo. Kljub temu pa je spremljanje njihovega vi\u0161ka \u0161e vedno aktualno. Tak\u0161no pravilno nastavljeno spremljanje bo omogo\u010dilo administratorju, da vnaprej napove staranje SSD-jev v skladu z dejanskimi trenutnimi obremenitvami, podjetni\u0161kega vodstva pa, da izra\u010duna kazalnike TCO (skupni stro\u0161ki lastni\u0161tva).<\/p><\/blockquote>\n
