[CB16] EXOTIC DATA RECOVERY & PARADAIS by Dai ShimogaitoCODE BLUE
Hard Disk Drives (HDD) have a hidden space for storing data. If malicious software is stored in this hidden area, it could lead to attacking computers even if they are air-gapped.
By abusing surplus space of HDD, such cyber attack against off-line industrial control systems could become possible.
Moreover, the software or any data in this hidden space can survive against formatting, OS reinstallation, malware destruction software and any conventional cybersecurity framework.
Let us call it "PARADAIS"
While the PARADAIS stays unactivated, LBAs are not mapped to the hidden data area. Therefore, even if the HDD is wiped several times such as 3-pass, 7-pass or 35-pass, it remains there as it is.
There has been no way to detect or erase the unidentified software at PARADAIS in advance when the HDD had been modified prior to your purchase or its installation. However, new solutions are being discovered by my ongoing research.
Who can predict that Windows OS may boot after the HDD is wiped by Enhanced Secure Erase ? It would be you at CODEBLUE2016.
The 2nd part of my presentation would be on DATA RECOVERY from HDD the platter surface of which has been damaged because of head crash, natural disaster or intentional destruction at crime scenes. Survey results of 12 cases show how effective the disk surface cleaning by DDRH was.

Castle is an open-source project that provides an alternative to the lower layers of the storage stack -- RAID and POSIX filesystems -- for big data workloads, and distributed data stores such as Apache Cassandra.
This presentation from Berlin Buzzwords 2012 provides a high-level overview of Castle and how it is used with Cassandra to improve performance and predictability.
What is Apache Kafka and What is an Event Streaming Platform?confluent
Speaker: Gabriel Schenker, Lead Curriculum Developer, Confluent
Streaming platforms have emerged as a popular, new trend, but what exactly is a streaming platform? Part messaging system, part Hadoop made fast, part fast ETL and scalable data integration. With Apache Kafka® at the core, event streaming platforms offer an entirely new perspective on managing the flow of data. This talk will explain what an event streaming platform such as Apache Kafka is and some of the use cases and design patterns around its use—including several examples of where it is solving real business problems. New developments in this area such as KSQL will also be discussed.
Under The Hood Of A Shard-Per-Core Database ArchitectureScyllaDB
Most databases are based on architectures that pre-date advances to modern hardware. This results in performance issues, the need to overprovision, and a high total cost of ownership. In this webinar, we will discuss the advances to modern server technology and take a deep dive into ScyllaDB’s shard-per-core architecture and our asynchronous engine, the Seastar framework.
Join us to learn how Seastar (and ScyllaDB):
- Avoid locks and contention on the CPU level
- Bypass kernel bottlenecks
- Implement its per-core shared-nothing autosharding mechanism
- Utilize modern storage hardware
- Leverage NUMA to get the best RAM performance
- Balance your data across CPUs and nodes for the best and smoothest performance
Plus we’ll cover the advantages of unlocking vertical scalability.
Analyzing IOT Data in Apache Spark Across Data Centers and Cloud with NetApp ...Databricks
This session will explain how NetApp simplifies the process of analyzing IoT data, using Apache Spark clusters across data centers and the cloud using NetApp Private Storage (NPS) for AWS/Azure, NetApp Data Fabric and NetApp Connectors for NFS and S3. IoT data originates at the edge in different geographical locations, and it can arrive at different data centers or the cloud depending on sensor location. The challenge is how to combine these different data streams across different datacenters to generate wider insights.
Learn how NetApp Data Fabric helps solve this challenge. In the Data Fabric architecture, the IoT data is ingested via Kafka into an Apache Spark cluster running in AWS/Azure, but the data is stored in NPS provisioned NFS share through NFS Connector. The IoT data in NPS can then be moved to on-prem datacenters, or on-prem IoT data can be moved to NPS or ONTAP Cloud for processing in AWS/Azure using NetApp SnapMirror Flex Clone or NFS Connector. We’ll also review how NetApp StorageGRID object storage maintains IoT data for archival purposes using S3 Target. The above options allow you to analyze IoT data from AWS, StorageGRID, HDFS or NFS, providing a feasible solution for deploying Spark clusters across datacenters.
Takeaways will include identifying Spark challenges that can be remedied by extending your Spark environment to take advantage of NPS; understanding how NPS and StorageGRID can provide a cost-effective alternative for dev/test, DR for Spark analytics; and understanding Spark architecture and deployment options that utilize data from multiple locations, including on-prem and cloud-based repositories.
Scylla Summit 2022: New AWS Instances Perfect for ScyllaDBScyllaDB
In this talk AWS’ Ken Krupa, Head of Specialized Solutions Architecture, will describe the architecture and capabilities of two new AWS EC2 instance types perfect for data-intensive storage and IO-heavy workloads like ScyllaDB: the Intel-based I4i and the Graviton2-based I4g series.
The Intel Xeon Ice Lake-based I4i series provides unparalleled raw horsepower for your most demanding workloads. Meanwhile, the Graviton2-powered I4g instances provide lower cost per storage on a power-efficient platform to deploy your cloud-native applications.
Ken will also describe the AWS Nitro SSD, a new form of high-speed NVMe storage with a Flash Translation Layer built with Nitro controllers, which powers both of these instance families.
ScyllaDB VP of Product Tzach Livyatan will then share benchmarking results showing how ScyllaDB behaves under load on these two instance types, providing maximum system utility and efficiency.

"Apache Spark is today’s fastest growing Big Data analysis platform. Spark workloads typically maintain a persistent data set in memory, which is accessed multiple times over the network. Consequently, networking IO performance is a critical component in Spark systems. RDMA’s performance characteristics, such as high bandwidth, low latency, and low CPU overhead, offer a good opportunity for accelerating Spark by improving its data transfer facilities."
"In this talk, we present a Java-based, RDMA network layer for Apache Spark. The implementation optimized both the RPC and the Shuffle mechanisms for RDMA. Initial benchmarking shows up to 25% improvement for Spark Applications."

Technical risks of putting a cache in front of your database– and what to do instead
Teams experiencing subpar latency commonly turn to an external cache to meet the required SLAs. Placing a cache in front of your database might seem like a fast and easy fix, but it often ends up introducing unanticipated complexity, costs, and risks. External caches can be one of the more problematic components of distributed application architecture.
Join this webinar for a technical discussion of the risks associated with using an external cache and a look at how ScyllaDB’s cache implementation simplifies your architecture without compromising latency. We’ll cover:
- Different approaches to caching (pre-caching vs. caching, side cache vs. transparent cache)
- 7 specific reasons why external caching ia a bad choice
- Why Linux’s default caching doesn’t work well for databases
- The advantages & architecture of ScyllaDB's specialized row-based cache
- Real-world examples of why and how teams eliminated their external cache with ScyllaDB
When your database is growing, you definitely need to think about other techniques like database sharding. SPIDER is a MariaDB Server / MySQL storage engine for database sharding. Using SPIDER, you can access your data efficiently across multiple database backends.
In this time we will introduce the following things.
1. why SPIDER? what SPIDER can do for you?
2. when SPIDER is right for you? what cases should you use SPIDER?
3. how long is SPIDER used in the big environment?
4. SPIDER sharding architecture
5. how to get SPIDER working?
6. multi dimenstional sharding technique with VP storage engine
7. roadmap of SPIDER
