Kev piav qhia

JHA-Q40WC201 yog 40G fiber ntau network daim npav rau cov neeg rau zaub mov, nws muaj ob lub 40G QSFP + interface, tuaj yeem txhawb nqa 40Gbps kis tau tus mob bandwidth, thiab txhawb nqa PCI-E X8 tus qauv qhov, xyuas kom lub network daim npav ua haujlwm tau zoo thiab ruaj khov ua haujlwm. Tsis tas li ntawd, daim npav network kuj txhawb VLAN, QOS lub tswv yim, khiav tswj thiab lwm yam dej num, haum rau nruab nrab thiab loj LAN daim ntaub ntawv.

LAN thiab Virtualization nta

♦ Network Virtualization offloads rau VXLAN thiab NVGRE

♦ Kev Sib Koom Tes Sib Koom Tes Muab ib qho xaim rau LAN thiab khaws cia: NAS (SMB, NFS) thiab SAN (iSCSI, FCoE)

♦ Kev them nyiaj yug Virtual Bridging - VEPA / 802.1Qbg, BPE / 802.1Qbh

♦ Lub Cev Muaj Zog - Txog li 8 ib qhov chaw nres nkoj, mus txog 16 rau ib lub cuab yeej

♦ Kev them nyiaj yug rau 128 Virtual Device Queues (VMDq) ib qhov chaw nres nkoj

♦ Hardware Queue Pairs – Mus txog 1.5K (tsis yog-RDMA); mus txog 256K (RDMA)

♦ Virtualization - Alleviating hypervisor I/O bottlenecks los ntawm kev muab cov dej sib cais rau Virtual Machine (VMs)
