Q&A]
Abstract:
In this talk, I will capture recent advances in flash solid-state drive (SSD) technologies,
especially focusing on computational storage and media geometry aware interfaces. The first
system to discuss is Biscuit; it is a programming model and an implementation of the same on
a flash storage system. YourSQL builds on Biscuit to achieve over 15x performance gain for
top five queries of TPC-H. I will also describe a device that packages a high performance
FPGA and SSD together. Next, I will talk about several recent SSD interface standards, like
open-channel SSD and zoned namespace. They try to circumvent the traditional LBA interface
and expose the geometry of the underlying flash media. Essentially, they aim to optimize the
media usage. Despite their benefits, I observe that there are challenges to users of those
interfaces, requiring further progresses. Before closing, I will discuss how SSDs can better
service multi-tenancy workloads through isolation concepts and how rich usage data in the SSD
can reveal opportunities for more informed server infrastructure management.

Hugo Patterson (CTO and Co-founder, Datrium)
[
Speaker Bio]
Bio:
Hugo Patterson was co-founder of Datrium which developed disaster recovery as a service software and systems
that integrated high-performance primary storage capabilities with cost-effective data protection and disaster
recovery orchestration for virtual machines. Hugo served in various roles including Chief Scientist, Chief
Architect, CTO, and VP of Engineering. Datrium was acquired by VMware in 2020. Its technology is available in
the VMware Cloud Disaster Recovery SaaS solution.
Prior to Datrium, Hugo served as EMC Fellow and CTO of the Backup Recovery Systems Division of EMC which
includes the Avamar, Data Domain, Disk Library, and Networker product lines. Hugo joined EMC in July of 2009
on its acquisition of Data Domain. He started at Data Domain in March 2002, shortly after its founding, and
served as Chief Architect from May 2002 till December 2008 when he was named CTO. Data Domain had its IPO
in 2007.
From November 1999 to March 2002, Hugo was the lead architect for data availability and management at Network
Appliance Inc., a provider of storage and data management solutions. There, he pioneered the use of snapshots
and replication as an alternative to conventional backup by building the SnapVault product and instigating
development of the Nearstore product line, which leveraged SATA disks to reduce costs.
Dr. Patterson holds a B.A. in Mathematics from the University of Chicago, an M.S. in Electrical Engineering
from the University of Maryland and a Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University.
Hugo was the inaugural recipient of the CMU Parallel Data Lab Distinguished Alumni Award. He grew up in New York
City (Manhattan).

Bio:
Dr. Niraj Tolia is the General Manager and President of Kasten (acquired by Veeam), which he founded in
order to solve the problem of Kubernetes backup and disaster recovery. He also sits on the Governing Board
of the Cloud Native Computing Foundation (CNCF).
Niraj has held multiple leadership roles in the past including Senior Director of Engineering for Dell EMC's
CloudBoost group and VP of Engineering, Chief Architect, and Staff Engineering at Maginatics, acquired by Dell
EMC. Niraj also advises and invests in startups including Hedvig, a company acquired by Commvault. In a previous
life, he was a Senior Researcher at HP Labs.
Niraj received his Ph.D., MS, and BS in Computer Engineering from Carnegie Mellon University, where he was a part
of the Parallel Data Lab. His research concentrated on distributed storage systems with an emphasis on deduplication
and wide area network data transfer.
