Netgear Launches XS728T 28-port 10-Gigabit Smart Managed Switch

In early 2013, Netgear launched the XS708E (8x 10GBASE-T with 1x shared 10G SFP+) unmanaged switch, the XS712T (12x 10GBASE-T with 2x shared 10G SFP+) smart managed switch and the XSM7224 (24x 10GBASE-T with 4x 10G SFP+) fully managed switch. Netgear is announcing the XS728T today, adding a new member to the smart managed switch family. The XS728T comes with 24x 10GBASE-T ports and 4x dedicated 10G SFP+ ports.

Netgear claims that the ProSafe XS728T is the industry’s first 28-port 10-Gigabit Smart Managed Switch. It falls in the same category as the XS712T with respect to the management capabilities. We have been having a good experience using the XS712T in our 10G-capable NAS testbed. It is not a fully managed switch, but does manage to be cost-effective in the process.

Compared to the XS712T, the XS728T brings support static IPv6 routing. Netgear advertises L2+/Layer 3 Lite features in the XS-T series making them suitable for core switches in SMB environments. The datasheet provides information about the L2+ / L3 Lite features.

The performance aspects of the XS712T and the XS728T are summarized in the table below.

The datasheet provides detailed technical specifications. One of the aspects that caught my eye was the acoustic levels. While the XS712T was rated at 49.7 dBA (We use it in our testbed, and the noise is pretty much what makes the usage of the unit difficult during evaluation in a home lab setting), the XS728T comes in at 41.6 dBA. I was also curious about the core platform. Netgear indicated that the XS728T uses Marvell silicon inside. These are fabricated in a smaller process node (we believe it is the Alaska transceivers and some combination of Prestera DX packet processors fabricated in 28nm). These operate a bit cooler, reducing the thermal load. The number of fans in the XS728T has also been doubled to four (compared to two in the XS712T). Taken together, these changes have enabled Netgear to run the fans slower and generate less noise.

The XS728T has a MSRP of $4624. However, as is usual with enterprise equipment, final pricing for end customers may vary from one reseller to another.

Linksys EA8500 – First MU-MIMO Enabled 802.11ac Router Set to Ship

Readers following our wireless networking coverage must be quite familiar with the developments in 802.11ac land. As a recap:

• The first 3-stream 802.11ac routers (based on the Broadcom BCM4706 chipset) started shipping in May 2012, with Buffalo Technologies and Netgear leading the way. There were marketed as AC1750 units (3×3 5 GHz providing  up to 1300 Mbps and 3×3 2.4 GHz providing up to 450 Mbps). The street pricing of the AC1750 routers started to go down once Qualcomm started shipping their first-generation 802.11ac router platforms in products such as the TP-LINK Archer C7 in April 2013.
• In Q4 2013, a wave of AC1900 units started to hit the market. Netgear’s Nighthawk R7000, a popular member in this series, still continues to sell well in the market. These units still used a 3×3 5 GHz radio for up to 1300 Mbps, but the 2.4 GHz had some proprietary Broadcom extensions (TurboQAM) to support up to 600 Mbps in an end-to-end Broadcom environment.
• In 2014, Quantenna began to bring their technology lead in the Wi-Fi space to the market with their Wave 2 4×4 802.11ac chipset. Despite being announced at CES 2014, the Asus RT-AC87U began to ship in July with the QSR1000 radio coupled with a Broadcom SoC. Netgear started to ship the same radio coupled with a Qualcomm IPQ8064 SoC in the Nighthawk X4 in September 2014. The QSR1000’s Wave 2 feature set includes support for MU-MIMO, but neither of these routers shipped with MU-MIMO enabled in the firmware (citing lack of client support at that point of time). Given the 4×4 configuration, these routers were tagged as AC2350 / AC2400 units (600 Mbps in the 2.4 GHz band and 1733 Mbps in the 5 GHz band)
• In the midst of these Wave 2 product launches, Qualcomm announced plans for their Wave 2 802.11ac platforms (both routers and clients) in April 2014. Broadcom, being late to the Wave 2 party, decided to bring out the XStream platform with dual 5 GHz radios (six-stream configuration) also in April. They were able to get it quickly into the market too, with the Netgear Nighthawk X6 R8000 becoming available in June 2014.
• At CES 2015, we saw the first set of routers based on Qualcomm’s QCA9880 4×4 Wave 2 802.11ac router platform getting announced. Vendors such as TP-LINK and TRENDnet were expecting their AC2600 class routers to ship towards the middle of the year.

Coming back to today’s announcement regarding the EA8500, Linksys is becoming the first vendor to start shipping a QCA9980-based router. The important aspect here is that the router will ship with MU-MIMO enabled. Client devices with MU-MIMO enabled are also coming into the market just now (more on that in our detailed review). Hopefully, this announcement will spur both Netgear and Asus to enable MU-MIMO in the firmware for their Quantenna-based routers.

The salient features of the EA8500 router are listed below:

• 4×4 802.11ac with MU-MIMO and beamforming support
• QCA9980 radio + 1.4 GHz dual-core IPQ8064 SoC
• Simultaneous dual-band operation (5 GHz 802.11ac – 1733 Mbps, 5 GHz 802.11n – 600 Mbps, 2.4 GHz 802.11n – 800 Mbps)
• 1x USB 3.0, 1x USB 2.0 / eSATA
• 4x 1Gbps LAN, 1x 1Gbps WAN
• Adjustable antennas for optimal performance

One important point to note is that MU-MIMO capabilities will translate into real benefit only when there are multiple MU-MIMO-capable client devices talking to the router simultaneously. This will probably be a common scenario in enterprise Wi-Fi deployments soon. However, in a typical household, we would imagine that a situation involving multiple MU-MIMO clients is probably at least a good year away. Qualcomm is targeting an end-to-end play here, as the announcement made last year included a number of products in the client space with MU-MIMO capabilities.

Linksys is accepting pre-orders at $280 for the EA8500 today with shipments slated for May 10, 2015. Wide retail and e-tail availability is also expected starting next week. There is no doubt that MU-MIMO will be the most efficient way to boost Wi-Fi performance in the near future, and it is good that Linksys and Qualcomm are teaming together to accelerate its market adoption.
