This talk highlights some elegant designs, practical trade-offs, difficult technical challenges, and future directions in this evolution.</span></font></div><div class=""><br class=""></div><div class=""><font face="Avenir-Book" class=""><span class="" style="font-size: 14px;"><b class="">Bio:</b> Ram is a Technical Director in the WAFL File System team. He has worked at NetApp far too long building storage system software. During this time, he has had the good fortune to work in all areas of the file system, such as journaling, write allocation, garbage collection, buffer cache, resiliency, repair, and performance, even as different storage media (SSD, flash, cloud) have been incorporated into WAFL. In the last few years, he has been using his weekends to write and submit papers on WAFL designs to academic conferences. Ram has a PhD from The Ohio State University and a B.Tech from the Indian Institute of Technology, Madras.</span></font></div><div class=""><br class=""></div><div class=""><font face="Avenir-Book" class=""><span class="" style="font-size: 14px;"><b class="">Host:</b> Haryadi Gunawi</span></font></div><div class=""><font face="Avenir-Book" class=""><span class="" style="font-size: 14px;"><br class=""></span></font></div><div class=""><b class="" style="font-size: 14px;"><font face="Avenir-Book" class="">PDF:</font></b></div><div class=""><br class=""></div><div class=""></div></body></html>
