DataCore SANsymphony-V – time drift issues

Donnerstag, April 4th, 2013

datacore_logo.jpg vtricks_logo.jpg   SANsymphony-V relies on Windows Communication Foundation (WCF) to keep a secure connection between the two DataCore servers. Unfortunately WCF doesn’t tolerate time changes greater than 30 seconds. So if we look again at the log message posted by the windows time service.

The system time has changed to ‎2013‎-‎03‎-‎24T00:01:49.899001000Z from ‎2013‎-‎03‎-‎24T00:01:13.333675100Z

So the system time has been changed by more than 30 seconds. This will cause the connection between SANsymphony-V nodes to break. This will force the DataCore server to perform some actions like “reviewing” its inventory to know exactly know what’s going on. And this is what causes these alarming but innocuous log messages


DataCore SANsymphony-V R9.0 – redundant mirror paths properly configured

Sonntag, Februar 24th, 2013

datacore_logo.jpg   vtricks_logo.jpg … as you can see we got 4 paths between our storage servers even we got only two physical connections. This is because a storage node uses both (or more) ports to login on his partner node and vice versa what results in 4 “logical” paths. Only then you will be able to unplug a cable with no impact on your virtual disks because then the “active” path can failover to his “standby” path

DataCore SANsymphony-V 8.1 – Tiered Storage organize storage into different groups to best meet different availability performance and cost requirements

Freitag, August 5th, 2011

datacore_logo.jpg   DataCore SANsymphony-V Tiered storage reduces costs and optimizes performance. You can reserve your most pricey disks for the most critical and demanding applications while you assign lower cost drives to lower priority workloads. Often customers choose Solid State Drives (SSD) for an exclusive set of workloads whereas they set aside relatively inexpensive large capacity SATA drives for online backups. The same application may take advantage of different tiers. For example a database applications may employ disks from the high performance high availability tier for critical log files but use low-end high-density drives for its scratch files
