Input/output operations per second ( IOPS , pronounced eye-ops) yog ib qho kev ntsuas kev tawm tswv yim / tso zis uas siv los ntsuas cov khoom siv hauv computer xws li hard disk drives (HDD), hard state drives (SSD), thiab chaw cia khoom network (SAN).
Tsis tas li ntawd, koj yuav xam IOPS li cas?
Rau xam tus IOPS ntau yam, siv cov qauv no: Nruab nrab IOPS : Faib 1 los ntawm cov lej ntawm qhov nruab nrab latency hauv ms thiab qhov nruab nrab nrhiav lub sijhawm hauv ms (1 / (nruab nrab latency hauv ms + nruab nrab nrhiav lub sijhawm hauv ms).
IOPS suav
- Rotational ceev (aka spindle speed).
- Nruab nrab latency.
- Nruab nrab nrhiav sijhawm.
Tsis tas li ntawd, 4k IOPS yog dab tsi? 4K IOPS txhais tau tias "tus naj npawb ntawm I/Os ib ob rau kev thov ntawm 4KBytes ntawm cov ntaub ntawv".
Qhov thib ob, IOPS ua haujlwm li cas?
IOPS . Stands rau "Input/Output Operations Per Second." IOPS yog ib tug metric siv los ntsuas rau kev ua tau zoo ntawm ib tug cia khoom los yog cia network. Cov IOPS tus nqi qhia tias muaj pes tsawg qhov sib txawv ntawm cov tswv yim lossis cov khoom tso tawm ib lub cuab yeej lossis pab pawg ntawm cov khoom siv tuaj yeem ua tau hauv ib thib ob.
Muaj pes tsawg IOPS puas muaj SSD?
Yog koj ua tau 't ua lej los yog hlub yav dhau los, koj nyiam spinning xeb. Yog koj txaus nyiam SSDs . SSDs yog pheej yig dua drives siv cov metric feem ntau: $/GB/ IOPS . 1 SSD yog 44,000 IOPS thiab ib tug hard drive yog 180 IOPS.

S txhais li cas ntawm Instax Mini 9?
Nyob rau sab nraub qaum, koj yuav pom tias cov yeeb yaj kiab txee tso saib (cov naj npawb ntawm cov txhaj tshuaj ntxiv) yog teem rau S.

Txhawm rau ua qhov no, tsuas yog qhib lub koob yees duab los ntawm nias lub pob loj nyob ncaj qha ntawm lub lens thiab nias lub khawm kaw
Puas muaj lub app txhais lus txhais tes?
Lub mobile app hu ua "Augmented Reality Sign Language" thiab tuaj yeem txhais ntawm cov ntawv sib txawv ntawm hom lus nrog rau ntawm cov lus hais thiab kos npe. Lub app tso cai rau tus neeg lag ntseg kos npe, thiab tom qab ntawd lub app hloov qhov no mus rau hauv cov ntawv thiab hais lus rau cov neeg siv tsis kos npe nkag siab
SQL Server xam IOPS li cas?
IOPS tiag tiag sib npaug ntawm qhov sib npaug ntawm qhov sib faib los ntawm latency, thiab IOPS los ntawm nws tus kheej tsis xav txog qhov hloov pauv loj rau ib tus neeg hloov chaw disk. Koj tuaj yeem txhais IOPS rau MB / sec thiab MB / sec rau latency ntev npaum li koj paub qhov tob tob thiab hloov pauv loj
IOPS txhais li cas hauv AWS?
IOPS (kev tawm tswv yim / tso zis ua haujlwm ib ob) yog qhov kev ntsuas kev ua tau zoo siv los paub qhov txawv ntawm ib hom cia los ntawm lwm qhov. Zoo ib yam li cov cuab yeej tsim khoom, AWS koom nrog IOPS qhov tseem ceeb rau lub ntim khoom txhawb nqa kev xaiv cia. Raws li IOPS qhov tseem ceeb nce, kev xav tau kev ua haujlwm thiab cov nqi nce
Nws txhais li cas los tsim ib txoj haujlwm txhais ntawm lub tswvyim?
Qhov tseeb, lub ntsiab lus txhais qhia koj tias lub tswv yim txhais li cas, thaum lub ntsiab lus ua haujlwm tsuas yog qhia koj seb yuav ntsuas nws li cas. Lub tswv yim txhais tau hais tias koj cov kev tsim kho yog dab tsi los ntawm kev piav qhia seb lawv cuam tshuam li cas rau lwm cov qauv. Qhov kev piav qhia thiab tag nrho cov tsim nws hais txog yog abstract
