User authentication to multiple AD domains in Splunk

You have Splunk, 2 LDAP strategies, user from LDAP1, group from LDAP2
and you cant in Splunk assign role from LDAP2 to user from LDAP1 ;(

You can configure mutiple LDAP servers and Splunk will try each one. The current limitation seems to be that the user must be able to authenticate and be in a splunk-role-assigned group on the same LDAP server ("scheme").

SAP HANA Adoption of Non-Volatile Memory - VLDB Endowment

Good old document with description of internal mechanics - SAP HANA and NVRAM technology

http://www.vldb.org/pvldb/vol10/p1754-andrei.pdf

Quote: "Currently, the following storage types are supported: 1. DAX-enabled filesystem backed by real NVRAM DIMMs 2. Traditional file system backed by SHM/SSD/HDDs (Simulation) The programming model is based upon memory-mapped files, and hence the NVRAM Block Provider not only leverages the load/store capabilities of persistent memory, but can also work correctly with any other storage technology (e.g. SSDs)."
