Adaptec has announced a new RAID Storage Plate defined by business level software with support for up to 32 NVME SSDs. The new Smartraid 4300 series supports SSDS PCIE 4.0 and 5.0 with sequential reading speeds up to 291 GB/S when fully saturatedthat is, with the 32 SSDs supported at simultaneous use.
It comes in a low profile MD2 format and fits a single PCIE X16 slot. The plate supports secure startup, secure update, certificate, pre-initialization UEFI management and RAID 0, 1, 10, 5 and 50 modes.
And this is still just a small sample of what she is capable. There is also support for native 4K and 512 bytes NVME devicesHot-Plug Support, Hot Spare and Smart Support. And there is a variety of personalized security features for corporate users.

ADVANTAGE ABOUT TRADITIONAL RAID
The new plate is tailored to corporate data centers and is designed to support the CPU, discharging CPU I/O data to increase performance. Smartraid 4300 does not connect directly to any SSD, but route the data of I/O for itself through software.
This form of raid is known as Software-defined storage (Software-Defined Storage, SCS)a raid strategy that defiles the hardware of the software. And it is very similar to Arrays Raid on virtual machines, where the software determines how I/O traffic is managed.
And this approach has several advantages over traditional RAIDs.
OEMs and system developers have The freedom to combine NVME SSDS in a raid array and are not linked to the supplier’s specific hardware. The SCS is also much more scalable and does not depend directly on the RAID plate to feed all SSDs.
Effective gains
Arrays Raid SCS can also be faster than traditional RAID settings, due to the absence of hardware limitations. Instead of the raid plate is the limiting factor, the SSDs themselves and the PCI link that connects them to the CPU are the limiting factors of performance.
And a Adaptec states an increase of up to 7x in I/O performance with Smartraid 4300 compared to the offers of the previous generation.
Assuming a network of 32 units fully saturated with SSDs compatible with PCIE 5.0, adaptc claims that The Smartraid 4300 series is able to operate at 128 kb/1 MB sequential reading speeds up to 291 GB/if 128 kB/1 MB sequential recording speeds up to 155 GB/s in a RAID 5 array on Linux.
Reconstruction times are evaluated up to 32 GB/SE 22.6 GB/s, respectively, with the same configurations.
