Intel's NVMe VRoC System Now Out



  • Anandtech takes a first look at Intel's new Virtual RAID on Chip or VRoC that is out now that is meant to bring high performance, and direct boot, to NVMe solid state storage devices on servers. Intel's naming here is confusing. It is not implying that this system is "Virtual RAID", but is a Virtual "RAID on Chip" system. It's real RAID, for sure. It's considered Hybrid RAID, rather than pure hardware or software, as it does use some legitimate hardware components to allow it to boot without needing an OS up and running first; but it still uses software for most of the RAID and relies on the core system CPU for RAID processing power. So it is not hardware RAID by any means, but isn't pure software RAID which would be unable to boot directly.

    Performance is not yet known as the product is very new. But seems likely that it will be very good.



  • If an SSD is rated at 1DWPD for 5 years and in actual use one only uses .2DWPD, does that mean that such an ssd would nominally last 25 years barring some other catastrophic hw failure not related to the destructive nature of flash program and erase cycles?

    All reliability is about chances of failure. So it’s likely to last that long.
