Title: HighPoint Updates NVMe RAID Cards for PCIe 5.0: 50 GBps+ Direct-
Attached SSD Storage

HighPoint Technologies has updated their NVMe switch and RAID solutions with
PCIe 5.0, and supporting up to eight NVMe drives. The new HighPoint Rocket
1600 (switch add-in card) and 7600 series (RAID adapters) are the successors
to the SSD SSD7500 series adapter cards introduced in 2020. Similar to its
predecessors, the new Rocket series cards are also based on a Broadcom PCIe
switch (PEX 89048). The Rocket 7600 series runs the RAID stack on the
integrated ARM processor (dual-core Cortex A15)

The PEX 89048 supports up to 48 PCIe 5.0 lanes, out of which 16 are dedicated
to the host connection in the Rocket adapters. The use of a true PCIe switch
means that the product doesn't rely on PCIe lane bifurcation support in the
host platform.

HighPoint's Gen 5 stack currently has two products each in the switch and
RAID lineups - an add-in card with support for M.2 drives, and a RAID adapter
with four 5.0 x8 SFF-TA-1016 (Mini Cool Edge IO or MCIO) connectors for use
with backplanes / setups involving U.2 / U.3 / EDSFF drives.

The RAID adapters require HighPoint's drivers (available for Linux, macOS,
and Windows), and supports RAID 0, RAID 1, and RAID 10 arrays. On the other
hand, the AIC requires no custom drivers. RAID configurations with the AIC
will need to be handled by software running on the host OS. On the hardware
side, all members of the Rocket series come with an external power connector
(as the solution can consume upwards of 75W) and integrate a heatsink. The
M.2 version is actively cooled, as the drives are housed within the full-
height / full-length cards.

The solution can theoretically support up to 64 GBps of throughput, but real-
world performance is limited to around 56 GBps using Gen 5 drives. It must be
noted that even Gen 4 drives can take advantage of the new platform and
deliver better performance with the new Rocket series compared to the older
SSD7500 series.

The cards are shipping now, with pricing ranging from $1500 (add-in card) to
$2000 (RAID adapters). HighPoint is not alone in targeting this HEDT /
workstation market. Sabrent has been teasing their Apex Gen 5.0 x16 solution
involving eight M.2 SSDs for a few months now (involving a Microchip PCIe
switch. Until that solution comes to the market, HighPoint appears to be the
only game in town for workstation users requiring access to direct-attached
storage capable of delivering 50 GBps+ speeds.
