Will Netgear Switches Support NVMe-oF?
We have upgraded the premise to Cat6 Ethernet. Our current NAS using HDD (SATA) runs at sustained transfer speeds of 300MB/s Write and 600MB/s Read. However, our existing switching infrastructure is still on 1Gbps.
We would like to upgrade our switches to support 10Gbps over Cat6 Ethernet now to take advantage of the faster NAS HDD (SATA) speeds.
We would like this switch upgrade to accomodate faster sustained transfer rates (and quicker) provided by NVMe-oF. We will upgrade the NAS to an NVMe solution sometime in the future 2-3 years. Note: We understand the 10Gbps network will likely be the new bottleneck with NVMe Flash.
We have the following products in mind (attached to ticket Model):
- [Core] XS724EM
- [PoE] GS724TPv2
- OR [PoE] GSM7226LP
PoE used for IP-Cameras & Access Points.
Will current Netgear switches support NVMe-oF (now or in the future)?
Re: Will Netgear Switches Support NVMe-oF?
To early ... and uncertain if 10 GbE will play a role in NVMeoF at all - trend goes to 25 GbE, 100 GbE, 400 GbE. You get the idea.
Further on, the players in the market seem not having to agreed on a common standard, various approaches and protocols like iWARP (Internet Wide Area RDMA Protocol), RoCEv2 (RDMA over Converged Ethernet v2), or FCoE (FIber Channel over Ethernet).
The requirements for the Ethernet transport vary - from the Intel preferred iWARP which does not require any Lossless Ethernet, over RoCEv2 (Mellanox preferred) requiring Lossless Ethernet support with ECN (Explicit Congestion Notification), and finally FCoE requiring DCB Lossless Ethernet (Data Center Bridging, Cisco's preference).
As of writing, Netgear does support DCB with FCoE sniffing on the M6100 Series - this should give you an idea where these technologies belong to: It's about bringing fast block based storage to servers, say NVMe blocks to controllers - but it's not intended to replace e.g. SMB protocol based access.
The XS724EM (the only 10 GbE switch you listed) is a Smart Managed Plus switch, the top of the line model for very very basic management - almost "non-managed" switches with some added capabilities. So very unlikely to gain DCB/FCoE sniffing.
