  • Defining Software Defined Storage (SDS), what it is, and isn’t.

    UPDATE 11/28/2017 Over the last 4 years we’ve seen strong adoption of SDS with a growth rate over 100% YoY at OSNEXUS.   Today we see our storage grid technology in QuantaStor being a key differentiator for customers with hyper-scale deployments, rack-scale deployments and multi-site deployments. Things have changed alot on… Listen ⇢

  • Integrating ZFS

    UPDATE 11/28/2017 Since I wrote this article years ago many things have changed so here’s a quick update.  Today 90% of our deployments are ZFS based and we only use XFS within our Ceph deployments for OSDs.  Even that use of XFS will be phased out in 2018 with the… Listen ⇢

  • Hybrid SSD storage & LSI MegaRAID CacheCade Pro v2.0

    UPDATE 11/28/2017 Over the last 6 years we’ve seen LSI be acquired by Avago which was then acquired by Broadcom but unfortunately we’ve not seen many innovations in hardware RAID.  I’d been hoping to see things like bit-rot correction and smart drive rebuilds come to market but it’s still not… Listen ⇢
