Cluster in box, advanced version
The first time we wrote about the cluster in the box almost a year and a half ago , the product itself was launched into a series almost two years ago.
Since then, reviews have been collected and analyzed, gained considerable experience operating systems in real conditions, and Intel is changing the generation of processors.
It's time to update the model, remove the shortcomings and improve where possible.

The Hyperion RS420 G4 model is designed for 12 disks of 3.5 ", however, a significant number of people asked to put SSD and SAS 10 / 15K spindles in 2.5" versions, so the release of the chassis with 24 baskets under 2.5 "disks suggested itself. And the demand was so great That version 3.5 "will be launched only by the summer.

The disks for OS installation were inside, this creates certain inconveniences during production and maintenance. Yes, there are two of them, but the mirror does not negate the need to change the failed drive. If you take the traditional approach, then you need to find a place on the rear panel for the placement of two baskets for disks 15 mm thick, which is impossible - you will have to cut expansion slots. There were even ideas to place two seats in one basket, one after another. This radically simplifies the replacement, but does not eliminate the need to shut down the system before replacing. Unacceptable option.
However, 15 mm is a standard for nearline drives, our customers have always installed an SSD, so you can do with a basket for 7 mm drives. At the same time and make the fasteners without the use of screws, flash vibration is not afraid :)

The internal interface on the Intel i350 is stable, but still wanted to quickly. His place was taken by Mellanox ConnectX 3, it is not only an increase in bandwidth 10 times, but also support for RDMA. 10 gigabit bandwidth will not be superfluous.
CX3 and let the migration be instant!
The next item that I wanted to improve was an expander. We not only switched to 12G from Avago / LSI, but also made it removable!
Remove all
Along the way, the problem of extensibility was solved, 4 miniSAS HD ports were output from each server instead of one on the previous generation.
This allows you to make 4 parallel cascade of shelves and build all flash solutions with great performance potential.
RS420 G5
Significantly changed the board with expansion slots.
As it turned out, no one needs 10G Base-T, so 10G SFP + ports are now offered by default.
Clusters with software arrays (on Windows Storage Spaces and Linux) have become the most popular, so LSI3008 has been registered as a mezzanine card by default, reducing its cost.
RS420 G5
From small amenities - all baskets received a sticker with a serial number, servers are indicators of placement in the chassis and labels for pasting labels with a signature.
The system also got into our Shared DAS lab and is available for experimentation.
