SCALEIO 2.0 NOW AVAILABLE

SCALEIO 2.0 NOW AVAILABLE

EMC has released ScaleIO 2.0 couple of days ago. More information – https://community.emc.com/docs/DOC-52581

Some new features (source ScaleIO 2.0 release notes):

  • Extended MDM cluster – introduces the option of a 5-node MDM cluster, which is able to withstand two points of failure.
  • Read Flash Cache (RFcache) – use PCI flash cards and/or SSDs for caching of the HDDs in the SDS.
  • User authentication using Active Directory (AD) over LDAP.
  • The multiple SDS feature – allows the installation of multiple SDSs on a single Linux or VMware-based server.
  • Oscillating failure handling – provides the ability to handle error situations, and to reduce their impact on normal system operation. This feature detects and reports various oscillating failures, in cases when components fail repeatedly and cause unnecessary failovers.
  • Instant maintenance mode – allows you to restart a server that hosts an SDS, without initiating data migration or exposing the system to the danger of having only a single copy of data.
  • Communication between the ScaleIO system and ESRS (EMC Secure Remote Support) servers is now supported – this feature replaces the call-home mechanism. It allows authorized access to the ScaleIO system for support sessions.
  • Authenticate communication between the ScaleIO MDM and SDS components, and between the MDM and external components, using a Public and Private Key (Key-Pair) associated with a certificate – this will allow strong authentication of components associated with a given ScaleIO system. A Certificate Authority certificate or self-signed certificate can be used.
  • In-flight checksum protection provided for data reads and writes – this feature addresses errors that change the payload during the transit through the ScaleIO system.
  • Performance profiles – predefined settings that affect system performance.

ScaleIO can be downloaded from EMC website – http://www.emc.com/products-solutions/trial-software-download/scaleio.htm. ScaleIO 2.0 supports VMWare (5.5 and 6.0), Linux and Windows.
