<div><font size=2 face="sans-serif">Dear Team,</font>
<br>
<br><font size=2 face="sans-serif">In OpenStack Swift, built-in replication
technique is used to provide 3x+ data redundancy that is enabling OpenStack
to provide high availability. We are studying use of <b>Information Dispersal
Algorithm(IDA)</b> as a technique instead of replication to provide high
availability along with security.</font>
<br>
<br><font size=2 face="sans-serif">We would like to know,</font>
<br><font size=2 face="sans-serif">1. Was
it considered in Swift before? If so, can you please share your opinion?</font>
<br><font size=2 face="sans-serif">2. Will
this fit into existing Swift architecture that supports eventual consistency?
</font>
<br><font size=2 face="sans-serif">3. Do
you see advantages like storage efficiency, security etc. of using this
technique over replication?</font>
<br>
<br><font size=2 face="sans-serif">Any pointer/suggestions/guidance in
this regard will be appreciated.</font>
<br>
<br><font size=2 face="sans-serif">More information about IDA can be found
