Cov txiaj ntsig kev xeem qhia tau tias muaj txiaj ntsig zoo rau Dell R730xd platforms thaum siv SanDisk DAS cache caching piv rau HPE SmartCache, thiab NVMe PCIe SSD kev txhawb nqa muab txiaj ntsig ntau dua. Hauv OLTP simulations, R730xd tau pom txog 3 zaug siab dua IOPS vim kev siv SanDisk DAS Cache thiab SAS SSDs thiab 6 npaug siab dua vim siv SanDisk DAS Cache + NVMe PCIe SSDs piv rau HPE's SmartCache. Kev siv CPU siab dua nrog SanDisk DAS Cache, thiab kev siv CPU ntau dua nrog SanDisk DAS Cache + NVMe PCIe SSDs, tsuas yog qhov tshwm sim ntawm ntau dua IOPS suav. thiab, ntawm qhov tsis sib xws, qhia pom kev siv ntau dua ntawm cov peev txheej processor.
Yog li, yog tias hauv HP nrog 6% kev siv qhov tshwm sim hauv IOPS yog 41, uas yog, 1% ntawm cov khoom siv hluav taws xob tau siv rau 0,15 txhiab IOPS, tom qab ntawd hauv cov ntaub ntawv ntawm Dell R730xd peb muaj 16% noj ntawm 264 txhiab, uas. muab qhov ntsuas tau zoo dua - 0,06% ntawm cov peev txheej processor ib 1000 IOPS.
Ntawd yog, nyob rau hauv cov nqe lus ntawm kev siv processor, Dell kuj hloov mus ua tau zoo dua (2,5 npaug), txawm hais tias nws muaj processor siv qhov tseem ceeb uas yog % siab dua, tab sis, raws li peb muaj peev xwm txheeb xyuas, qhov no tsuas yog qhov tshwm sim ntawm kev ua haujlwm. ib tug loj tus naj npawb ntawm kev khiav hauj lwm, thiab yog li ntawd zoo productivity.
Yog li, Dell R730xd platform hloov tawm los ua kom muaj txiaj ntsig zoo dua li HP ProLiant DL380 (ntau zaus), ob qho tib si ntawm kev ua haujlwm thiab kev ua haujlwm tau zoo.
Cov txiaj ntsig ntawm Geekbanch 3 xeem Dell R730xd nrog E5-2640 v4 processor lossis vim li cas cov lus qhia processor thiab cov tswj cache tseem ceeb
Raws li peb tau pom saum toj no, peb tuaj yeem ua tiav qhov txiaj ntsig siab tshaj plaws tsuas yog thaum peb lub ntsiab lus - suav lub zog, khaws cia thiab sib txuas - sib npaug, raws li muaj peev xwm bottlenecks uas yuav tshwm sim nyob rau hauv ib tug unbalanced system yog minimized.
Tab sis dab tsi tseem ceeb heev yog lub platform processor txhawb rau ntau cov lus qhia thiab lawv cov kev ua tau zoo. Kuv twb tau hais saum toj no tias qhov sib txawv zoo li tsis tseem ceeb hauv ntau tiam neeg tuaj yeem ua lub luag haujlwm tseem ceeb hauv qee kis. Yog li, raws li cov txiaj ntsig ntawm kev xeem ywj pheej, E5-2650 v4 uas peb muab yog 70% zoo dua nyob rau hauv cov ntaub ntawv ntawm encryption (AES cov lus qhia) dua li E5-2650 v3.
Yuav ua li cas hais txog cov kev daws teeb meem "qab" los ntawm cov neeg sib tw los ntawm tus nqi qis, tab sis tsis yog ntu nqi? Vim li cas peb cov kev daws teeb meem zoo dua? Vim li cas peb cov kev daws teeb meem zoo tshaj? Cov lus teb yog yooj yim - peb cov servers tau thiab sib npaug. Txawm hais tias lawv yav dhau los muaj qis dua lossis tsawg dua ntawm kev nco, lawv yeej ib txwm sib npaug raws li peb qhov tsis tau piav qhia saum toj no. Xws li lub chaw ruaj ntseg cov ntaub ntawv nrog cov ntawv pov thawj xav tau los ntawm cov tuam txhab ntu thiab cov kev sib txuas lus zoo sab nraud uas muab qhov tsawg kawg nkaus latency los ntawm Netherlands, ob qho tib si rau cov teb chaws Europe, thiab rau Russia thiab Ukraine, thiab txawm tias
Tab sis tam sim no peb tau ua kom muaj kev sib tw hauv cov ntsiab lus ntawm cov ntsuas no, hauv 10 qhov chaw ib zaug, ib qho hauv Netherlands thiab 9 qhov chaw hauv Asmeskas, tab sis cia peb tsis tham txog peb, cia peb saib qhov kev xeem. Hmoov tsis zoo, qhov kev sim no tsuas yog muaj rau version E5-2640 v4, nrog 10, tsis yog 12 cores, rau peb lub platform.
Nws, ntawm chav kawm, tsis yog lub hom phiaj heev, vim nws tsis coj mus rau hauv tus account tag nrho cov zoo ntawm lub platform, tib SanDisk DAS cache uas peb tau tham txog, qhov kev ua tau zoo tiag tiag tuaj yeem ua tau zoo dua li cov khoom hluavtaws hauv ib qho tshwj xeeb. cas, ntau! Tab sis tseem muaj peev xwm nkag siab qee yam.
Cia peb mloog ntau cov lus qhia. Qhov taw qhia tshaj plaws yuav yog AES uas twb tau hais lawm, ntawm kwv yees li tib zaus qhov sib txawv ntawm qhov tseem ceeb rau 1st core tuaj yeem mus txog 1000 zaug nyob ntawm tus processor, cov lus qhia ntxiv uas tau muab piv tau pom qhov sib txawv ntawm cov txiaj ntsig los ntawm ntau txog 100 zaug.
Koj ua tau koj tus kheej thiab ua ib qho kev sib piv, tab sis tsis txhob hnov ββββqab tias qhov kev ntsuam xyuas no tsis yog qhov qhia tau meej, vim nws tsis coj mus rau hauv tus account lub hardware tag nrho, tab sis feem ntau characterizes lub processor.
Txawm li cas los xij, kuv vam tias cov txiaj ntsig no tuaj yeem pab tau rau koj thaum txheeb xyuas qhov ua tau zoo ntawm ib qho kev daws teeb meem.
Siv Dell R730xd servers li Bare Metal, yooj yim dua!
Qee tus ntawm peb cov neeg siv khoom tau txiav txim siab tso tseg kev siv VMware huab kev daws teeb meem hauv kev pom zoo ntawm Bare Metal kev daws teeb meem (hlau servers) thiab Dell R730xd platform tau pab lawv ntau hauv qhov no. Thiab peb tab tom tham ntawm no tsis yog tsuas yog hais txog huab cua pej xeem xwb, tab sis kuj hais txog cov neeg ntiag tug.
Vim li cas tib neeg thiaj li txiav txim siab li no? Hais txog huab cua pej xeem, txhua yam yog ntau dua lossis tsawg dua. Kuv tus kheej suav hais tias huab cua yog kev lag luam loj, yog tias ib yam dab tsi poob rau ntawd (thiab tag nrho cov huab poob sai dua los yog tom qab), nws ntog nyob rau ntawd ntev. Ib qho piv txwv yog tib lub npe nrov Amazon, uas nyob rau hauv ib lub sij hawm nteg rau ob peb hnub nrog rau cov kev pab cuam tseem ceeb rau kev sau cov ntaub ntawv kho mob telemetric, nrog rau cov ntaub ntawv ntawm lub plawv mob ntawm cov neeg mob siv lub pacemaker, uas tau raug saib xyuas los ntawm kws kho mob, ob peb. cov neeg tuag...Thiab tsis ntev los no, thaum peb lub tuam txhab Bitrix tau pw tsaug zog, nws tau pom tias yog vim li cas cov neeg ua haujlwm, uas tau tua qee lub tshuab, vim yog qhov yuam kev, muab cov nodes ntau dua li qhov tsim nyog, cuam ββtshuam rau kev tswj cov nodes, raws li qhov tshwm sim ntawm cov tshuab virtual tau rov pib dua li ntawm 5 teev vim qhov loj ntawm pawg ... Tab sis qhov no tsis yog qhov teeb meem nkaus xwb; nws yuav tshwm sim tias koj tau txais ib qho "lub raj mis" vim kev siv. ntawm huab los ntawm qee qhov haujlwm lossis qhov tsis muaj peev xwm tswj hwm nws cov txheej txheem sai sai kom tau raws li koj tus kheej xav tau.
Thaum nws los txog rau huab cua ntiag tug, hauv kev xav, virtualization simplifies muaj thiab kev puas tsuaj rov qab los. Hauv kev xyaum, muaj ntau qhov xwm txheej uas qhov no tsuas yog tsis muaj txiaj ntsig:
Nyob rau hauv cov ntaub ntawv ntawm kev teeb meem ntawm lub node, 15-30 feeb downtime yog txais.
Tsis yog txhua qhov haujlwm xav tau lub sijhawm ua haujlwm txog li 100%, tshwj tsis yog rau cov menyuam kawm ntawv uas tau siv los them ib duas las thiab xav tau 100%. Rau qee qhov haujlwm, 99,9% guaranteed uptime yog ntau tshaj qhov kev xaiv. Vim tias 0,1% yog qhov tsis muaj qhov siab tshaj plaws ntawm 44 feeb hauv ib lub hlis, uas tuaj yeem tshwm sim rau ntau yam tsis tau npaj tseg - vim yog kho vajtse tsis ua haujlwm lossis tsis muaj network. Peb lav lub network uptime ntawm 99,99% rau cov qauv kev daws teeb meem, uas tso cai rau qhov tsis muaj nyob ntawm tsuas yog 4 feeb hauv ib hlis. Yog tias tus neeg rau zaub mov txuas nrog 2 txoj kev ywj pheej uas dhau los ntawm kev sib txuas lus sib txawv thiab nws txoj kev khiav tsheb khiav los ntawm cov cores ywj siab, qhov kev lav phib xaub ntawm lub network yuav nce ntau zaus. Qhov no ua rau nws muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm cov tsev txhab nyiaj txawm tias qhov tsis muaj nyob ntawm 40 feeb hauv ib xyoos yog qhov tsim nyog, raws li kev lees paub. Nyob rau hauv qhov tseeb, lub sij hawm ntawm tsis muaj nyob yog heev tsawg. Nyob rau hauv 5 xyoo ntawm kev ua hauj lwm nrog cov ntaub ntawv chaw, yeej tsis tau muaj ib lub sij hawm thaum tag nrho cov servers los ua tsis muaj nyob rau tib lub sij hawm vim muaj teeb meem nrog lub network los yog hluav taws xob. Txawm hais tias thaum muaj kev kub ntxhov thoob ntiaj teb hauv Netherlands thiab ntau lub chaw cov ntaub ntawv tau dhau los ua tsis muaj - qee qhov tsis nco qab refuel diesel xyaw, qee qhov tsis muaj lub zog UPS txaus, hauv peb cov ntaub ntawv chaw tsuas yog tsawg dua li ib feem pua ββntawm cov servers tsis muaj sijhawm luv. lub sijhawm. Qee cov servers uas cov neeg siv xauj los ntawm peb, txawm tias dhau los, zoo li cov khoom siv tsis tu ncua, uas yuav ua tsis tau zoo dua li cov kev daws teeb meem tshiab, tsis tau rov pib dua ib zaug hauv 3 xyoos, ib yam li hauv 3 xyoo lawv yeej tsis tau poob net. . Puas yog tsis muaj 30 feeb rau 3 xyoos? Ntau tshaj, txawm rau cov tsev txhab nyiaj.
Thiab cov lus nug tsim nyog tshwm sim, yog vim li cas thiaj li them nyiaj tshaj? Nws mus yam tsis tau hais tias koj yuav tsum tsis txhob cia siab rau lub caij nyoog thiab yuav tsum tau mus tas li los ntawm lub hauv paus ntsiab lus ntawm qhov tsim nyog tshwj xeeb. Txoj cai tseem ceeb uas kuv nrhiav tau yog cov hauv qab no: qhov kev tshwj tseg yuav tsum raug nqi tsis pub ntau tshaj qhov poob uas yuav tshwm sim nyob rau hauv qhov xwm txheej ntawm lub sij hawm tsis muaj vim tsis muaj qhov no. Ntawd yog, yog tias lub sijhawm ua haujlwm tau lees paub tso cai tsis pub dhau 40 feeb hauv ib hlis, thiab yog tias tsis muaj nyob rau lub sijhawm ntawd, qhov kev poob yuav raug nqi ntau pua lossis ib txhiab daus las - xauj ib qho kev daws teeb meem ntxiv kom nce lub sijhawm lav yooj yim. ua tsis muaj kev nkag siab. Vim tias qhov tseeb, cov servers yuav tsis muaj nyob hauv txhua lub hlis rau 40 feeb, 40 feeb ntawm qhov tsis muaj yog qhov lav, qhov xwm txheej phem tshaj plaws. Uas tsis siv txhua hli, raws li kev xyaum tau qhia.
Txoj kev no, cov servers tuaj yeem yog qhov tseem ceeb yam tsis muaj lub luag haujlwm tseem ceeb, thiab thaum cov tswv haujlwm tsis xav hloov cov khoom thauj mus rau lwm tus neeg rau zaub mov, peb tuaj yeem zam qhov nyuaj ntawm kev tsim cov pawg tsis ua haujlwm thiab sib koom ua haujlwm tsis ua haujlwm.
Kev tsim khoom tsawg yog qhov tsis tsim nyog thaum lub sijhawm ua haujlwm. Ntau ntawm peb cov neeg muas zaub xaiv liab qab hlau daws teeb meem los ntawm Dell precisely vim li no; nws yog ntau pheej yig dua thiab muaj txiaj ntsig ntau los siv tag nrho cov khoom siv thaum lub sijhawm ua haujlwm, uas yog xyaum tsis raug rau kev nkag tsis tau, raws li peb tau tham txog, dua li them nyiaj tshaj rau huab. kev xaiv thiab kev ua tau zoo tib yam hauv huab, uas yuav raug nqi ntau zaus ntau dua li kev daws teeb meem. Cov huab thiab pawg tsuas tuaj yeem tsis txaus siab rau cov kev xav tau thiab yuav tsis raug nqi rau cov neeg siv khoom zoo li no.
Cov neeg siv khoom tsis xav them nyiaj ntau rau cov kev pabcuam uas muaj peev xwm tsawg. Feem ntau peb cov neeg siv khoom yog cov tuam txhab me me uas tsis muaj lawv tus kheej lub tuam txhab kev lag luam thiab nyiaj txiag los yuav lawv tus kheej kho vajtse. Kev yuav khoom kho vajtse tuaj yeem yog qhov teeb meem tiag tiag rau lawv thiab tsis muab kev ua haujlwm txaus, txij li lub sijhawm kho vajtse zoo li qub, thiab nws yog qhov txaj muag pov tseg cov khoom kim heev txawm tias tom qab 3 xyoos, ib lub sijhawm thaum lub tuam txhab loj hlob thiab ib yam dab tsi zoo dua. xav tau. Yog tias koj xauj Dell R730xd los ntawm peb, koj muaj sijhawm hloov mus rau lwm tus neeg rau zaub mov txhua lub sijhawm lossis tom qab ib xyoos yog tias koj xaiv qhov kev xaiv xauj nrog daim ntawv cog lus rau ib xyoos. Ntxiv mus, muaj lub sijhawm los txuag nyiaj rau VMware cov ntawv tso cai.
Siv Dell R730xd Servers rau Database Servers
Ntau ntawm peb cov neeg muas zaub uas siv cov database servers tau los hlub lub platform no. Thiab tsis tsuas yog vim hais tias, tsis zoo li Dell R730, xd version tuaj yeem muab kev txhawb nqa rau NVMe PCIe SSD drives, uas muab cov latency tsawg, uas yog qhov tseem ceeb heev rau cov kev daws teeb meem zoo li no. Tab sis kuj vim tias tus maub los ua haujlwm tau zoo kawg thaum ua haujlwm txawm tias cov pa 2,5 "SSDs uas peb muab rau cov neeg siv khoom.
Tau kawg, kuj tseem muaj qhov tsis zoo hauv Dell R730xd - tsuas muaj 1 tus tswj hwm, thaum Dell R730 nrog 26 tsav siv 2 tus tswj kho vajtse. Tab sis qhov no tsis yog qhov teeb meem tseem ceeb, txij li peb tau xaiv lub platform nrog 12 tsav bays thiab yog li ntawd koj yuav tsis tau txais lub fwj hauv daim ntawv ntawm kev tswj tsis txaus thaum ua haujlwm nrog lub platform no thiab ntau tus SSDs. Thiab qhov kom zoo dua nyob rau hauv daim ntawv ntawm lub peev xwm rau nruab NVMe PCIe SSD tag nrho npog qhov teeb meem no.
Raws li tau hais los saum toj no, tsis yog txhua tus xav tau cov ntaub ntawv sib koom ua ke; qhov kev ua tau zoo uas lub platform no tuaj yeem muab tau yog qhov tseem ceeb dua. Ib qho ntawm peb cov neeg siv khoom tau ua li ntawd, tso tseg qhov ntau dhau ntawm virtualization thiab tsim cov pawg ua haujlwm nyuaj, xauj VPS nrog rau kev mob siab rau cov ntaub ntawv thaub qab los ntawm lub ntsiab Dell R730xd server: Ntawm chav kawm, nyob rau hauv cov kev tshwm sim ntawm ib tug teeb meem nrog rau lub ntsiab node, yuav muaj ib co txo ββnyob rau hauv kev ua tau zoo thiab yuav tsum tau rau manually hloov, txawm li cas los xij, qhov no yog ib qho kev daws teeb meem ntau tshaj li tus nqi, muab cov peev nyiaj tsawg.
Peb tsis txhawb kom txhua leej txhua tus ua kom txuag tau nyiaj li no; qee zaum nws yog qhov ncaj ncees heev. Txawm li cas los xij, los ntawm kev nce cov peev nyiaj los ntawm tsuas yog $ 230 toj ib hlis, koj tuaj yeem them taus qhov zoo ib yam E5-2650 v4 node thiab txuas lawv ua ke hauv 20-Gigabit hauv zos network, uas, hauv paus ntsiab lus, yuav tso cai rau koj los tsim ib pawg me me nrog kev siv latency. Txawm tias tsis siv PCIe NVMe SSD drives.
Kev daws nws tus kheej yuav zoo li qhov no (nrog rau cov txheej txheem yooj yim ntawm cov tsav):

Kev nce lawv tus lej kom nce cov khoom lag luam tsis yog ib txwm ua rau muaj txiaj ntsig. Yog li, thaum kuaj nrog databases, peb pom tias kev daws teeb meem nrog 8 SSDs tsuas yog 4% ua tau zoo dua li kev daws nrog 35 SSDs.
Raws li kev pom zoo RAID qib, RAID5 tuaj yeem ua tau zoo heev hauv qee kis. Tseeb, RAID10 muab kev ua tau zoo dua, tab sis yuav ua li cas yog tias cov tsav tsheb nrawm heev uas siv lawv hauv RAID10 yuav ua rau tus maub los ua lub hauv paus? Hauv cov xwm txheej zoo li no, tsim HW RAID array RAID5 yog qhov muaj txiaj ntsig ntau dua siv cov khoom siv hluav taws xob kub dua li RAID10 (yog tias lub hom phiaj tsis poob ib nrab ntawm SSD quota).
Kuv puas xav tau tus maub los cache kom qhib los yog nws puas zoo dua rau lov tes taw nws? RAID maub los muaj qhov tsawg kawg ntawm kev nco, 1GB yog dab tsi thaum ua haujlwm nrog SSD? Nyob rau hauv cov ntaub ntawv nrog ceev ceev SSDs, tsis muaj qhov taw tes rau kev nyeem cache, vim los ntawm kev sau cov cim xeeb nrog kev nyeem ntawv, uas yuav tsis ua sai dua, vim tias SSDs twb tau nrawm txaus, peb tsis tso cov ntawv sau cache txaus, thiab , raws li paub, nyob rau hauv pheej yig SSDs - lub bottleneck yog sau ua hauj lwm, vim ib tug poob rau hauv kev ua tau zoo vim tsis txaus overprovisioning thiab 100% kev siv ntawm cov dawb quota (ib tenfold poob yog ua tau). Yog li ntawd, peb pom zoo kom tawm tsuas yog sau cache enabled. Li no kom ntseeg tau siab tshaj plaws ntawm cov tshuaj no.
Puas yog NTFS thaiv qhov loj me tiag tiag? Rau feem ntau khaws cia, 64KB yog qhia raws li qhov zoo tshaj plaws thaiv qhov loj rau kev ua haujlwm siab tshaj plaws. Tab sis feem ntau peb tuaj hla cov xwm txheej uas tus neeg siv khoom twb tau siv database server, siv qhov kev teeb tsa thawj zaug nrog tus qauv NTFS pawg loj ntawm 4KB. Txhawm rau txhim kho qhov no koj yuav tsum hloov kho cov tsav tsheb, tab sis puas yog qhov sib txawv tiag tiag uas loj hauv rooj plaub dav dav? Koj puas yuav tsum nthuav tawm koj tus kheej kom muaj sijhawm poob thiab tsis yooj yim cuam tshuam nrog kev tsiv teb tsaws chaw?
Tus maub los hauv Dell R730xd server muab kev ua haujlwm zoo txawm tias muaj 4 SSD drives thiab sau cache tau qhib (ib qho tseem ceeb heev, nyeem ntawv cache yuav tsum raug xiam vim nws tsis muaj qhov zoo, tab sis tsuas yog txo cov kev ua haujlwm ntawm kev sau ntawv vim. mus rau qhov tsis muaj qhov chaw rau tag nrho cov cache, raws li tau hais los saum toj no), uas txawm tias nrog tus qauv thaiv qhov loj ntawm 4KB, peb tau txais cov ntsuas kev ua tau zoo heev, zoo heev.
Txawm li cas los xij, peb yeej ib txwm txaus siab los ntsib thiab npaj siab muab lub platform zoo sib xws rau lub sijhawm rau cov neeg siv khoom los ua haujlwm yog tias qee yam tsis raug coj los ntawm lawv.
RAMdrive tseem hloov tawm sai dua li SSD drives. Yog tias koj cov lus nug tuaj yeem ua tiav hauv TempDB, xws li kev sib cais lossis kev sib koom ua ke, tom qab ntawd siv RAMdisk (ib qho kev pab cuam uas hloov ib feem ntawm koj RAM rau hauv cia) tuaj yeem tsim nyog heev. Yog li, tau muab piv rau qhov ceev ntawm 8 SSD drives hauv RAID10 nrog RAMdrive, peb pom tias nws yog li 4 zaug sai dua rau 4K sau cov haujlwm nrog qhov tob ntawm 32, uas ua raws nraim li kev ua haujlwm ntawm TempDB cov ntaub ntawv. Txawm tias muab 8 SSDs rau hauv RAID0 nws tsis tuaj yeem tuav cov txiaj ntsig ntawm RAMdrive.
RAID5 nyob rau hauv rooj plaub ntawm 8 SSD tsav tuaj yeem ua haujlwm zoo dua RAID10. 4K nyeem nrog qhov tob ntawm 32 yog kwv yees li 40% sai dua, uas tsis yog qhov xav tsis thoob muab cov yam ntxwv ntawm RAID5. RAID5 yeej nyob rau hauv kev ua tau zoo nyob rau hauv lwm yam kev ntsuam xyuas, piv txwv li, nrog sequential sau nws yog 20%, nws yog inferior tsuas yog nyob rau hauv 4K sau kev khiav hauj lwm nrog ib tug loj queue qhov tob (nyob rau hauv peb cov ntaub ntawv 32) thiab hloov tawm kom tsawg npaum li cas los ntawm 30%. Yog li kev siv RAID5 tuaj yeem ua rau qee qhov kev lag luam ncaj ncees.
Kev cia ntau dua tsis yog txhais tau tias sai dua. Thaum peb tab tom cuam tshuam nrog kev ua haujlwm me me, ntxiv cov tsav tsheb mus rau qhov array tshaj li qhov txwv tsis pub txhim kho kev ua haujlwm txhua. Nws yuav zoo li yog vim li cas? Nws hloov tawm tias txhua yam nyob ntawm lub peev xwm ntawm tus maub los, uas yog yuam kom sau cov ntaub ntawv mus rau tag nrho pawg ntawm cov tsav. Tias yog vim li cas peb thiaj li yuav cov platforms nrog qhov siab tshaj plaws ntawm 12 lub zog, txhawm rau txo qhov yuav ua rau lub raj mis. Txawm li cas los xij, koj yuav tsum tau saib qhov kev siv zog ntawm kev ua haujlwm hauv txhua qhov haujlwm, qee zaum 4 lub zog loj dua, hais tias 960GB, yuav yog qhov kev daws teeb meem zoo dua thiab muaj txiaj ntsig zoo dua li pawg ntawm 480GB drives.
