VPLEX Geosynchrony 5.2 supporting up to 10ms latency with HA/DRS

Duncan Epping · May 14, 2014 ·

I was just informed that as of last week VPLEX Metro with Geosynchrony 5.2 has been certified for a round trip (RTT) latency up to 10ms while running HA/DRS in a vMSC solution. So far all vMSC solutions had been certified with 5ms RTT and this is a major breakthrough if you ask me. Great to see that EMC spent the time certifying this including support for HA and DRS across this distance.

Round-trip-time for a non-uniform host access configuration is now supported up to 10 milliseconds for VPLEX Geosynchrony 5.2 and ESXi 5.5 with NMP and PowerPath

    Hi

    Should be VPLEX Metro, no Geo.

    Thanks

      Yeah correct, stupid way of shortening Geosynchrony of me, sorry for the confusion 🙂

    Hi Duncan, I got excited when I saw your post whether VPLEX GEO was released however you are referring to Geosynchrony software running on VPLEX. There are three VPLEX models as you know VPLEX Local, VPLEX Metro and VPLEX GEO. You are referring to VPLEX Metro latency improvement not talking about over distance >300km VPLEX GEO deployment.

    Geosynchrony indeed, stupid way of shortening it… sorry about that
