C40, C60 R3, go! Pure adds to FlashArray//C QLC flash range

by Jeremy

Pure Storage has added the new entry-level FlashArray//C40 R3 QLC flash storage array and a new top-of-the-range model – the C60 R3 – which takes raw capacity up near 2PB.

The C40 will scale from 247TB to 494TB, which slots it as a lower capacity option to the existing C60-366.

The C60 R3 tops the range now in terms of capacity with 1.8PB raw, around 5PB when data reduction methods have been applied. Both new products have uprated Intel Cascade Lake CPUs. There is also an incremental upgrade to the Purity operating system to version 6.1.

The FlashArray//C range is equipped solely with quad-level cell (QLC) NAND SSDs.

QLC is the latest iteration of NAND flash storage. It uses 16 different voltage levels to provide four bits of data per flash cell.

This offers high capacity but affects the lifespan of QLC flash chips and means they are better suited to sequential read input/output (I/O) rather than more mixed workloads handled by multi-level cell (MLC) flash, for example.

The FlashArray//C product range is an alternative to hybrid flash and HDD-based storage arrays for secondary Storage and bulk storage use cases, said CTO Alex McMullan.
“FlashArray//C is aimed fairly and squarely at removing the last of the hard-drive-based products from the datacentre.”

The company also announced several other enhancements to the FlashArray//C range as well as to the FlashBlade products.

Pure has extended its NVMe-over-fabrics support with the addition of Fibre Channel over NVMe. This comes in addition to existing support for RDMA/RoCE.

NVMe-over-fabrics extends the performance of NVMe drives out to hosts by bundling NVMe-transported packets/frames into a wrapper such as Fibre Channel.

That allows customers to benefit from NVMe’s performance end-to-end.

Connectivity has been extended to SMB 2 in FlashBlade, which McMullan said would help the company target high-bandwidth implementations such as video rendering. SMB 3 support would be available “in the summer,” he added.
Cross-protocol access control between NFS and SMB has also been added.
