Everything you wanted to know about iSCSI, but were afraid to ask. Presneted by David Black PhD who was a fundamental influence on the development of the protocol. This presentation is really fantastic!
Virtualization vulnerabilities, security issues, and solutions:
Virtualization is technological revolution that
separates functions from underlying hardware and allows
us to create useful environment from abstract resources.
Virtualization technology has been targeted by attackers
for malicious activity. Attackers could compromise VM
infrastructures, allowing them to access other VMs on the
same system and even the host.
This presentation emphasize on
the assessment of virtualization specific vulnerabilities,
security issues and possible solutions.

Leveraging Open Source to Manage SAN Performancebrettallison
Scope - The primary focus of this presentation is how to leverage open source software to help in managing Shared Storage performance. The storage server will be the focus with particular emphasis on ESS. This solution is a small one-off solution.
Avoiding Chaos: Methodology for Managing Performance in a Shared Storage A...brettallison
Scope - The primary focus of this presentation is on the methodology we use for managing performance in a very large shared Storage Area Network environment with a Primary focus on Distributed Systems and IBM Enterprise Storage Server. The focus on this presentation is methodology and NOT measurement. There are numerous excellent presentations already out there on measurement. However, there are several references in the back of the presentation to measurement tools.

When considering flash storage, there are many misconceptions and outright myths. Especially when equating consumer-grade flash (USB sticks) to enterprise-grade SSDs. In this webinar SanDisk Chief Architect, Adam Roberts, will discuss 5 myths of flash storage and highlight what you need to look out for when choosing a storage device to accelerate your data center storage. This webinar will cover:
1.Data Protection
2.Power Fail Protection
3.Temperature Throttling/Overheating
4.QoS for Performance
5.SSD Endurance
Stay tuned for future webinars which will look at the benefits of flash beyond performance…busting a few more myths on flash.

For nearly 30 years West Interactive Services has been creating communication solutions that empower enterprises worldwide to strengthen customer engagement. As a customer of WSO2 since 2012, WEST has built solutions using WSO2 API Manager, WSO2 Business Activity Monitor (WSO2 BAM), WSO2 Enterprise Service Bus (WSO2 ESB), WSO2 Data Services Server (WSO2 DSS), WSO2 Application Server and WSO2 Identity Server which facilitate nearly 300 million unique customer interactions each month.
The most recent deployment with WSO2 allows WEST interactive to expose client connections, data sources and application logic through a common protocol and messaging architecture. This is achieved using a combination of WSO2 API Manager, WSO2 ESB, WSO2 DSS, WSO2 Application Server and WSO2 Message Broker. This webinar will discuss the DevOps related theories and practices that have been followed by WEST during the process of designing, building and maintaining this part of the solution. These will address the following areas:
Design process of the solution
Deployment and production hardening practices
Runtime artifacts and lifecycle management
DevOps, virtualization and automation
Troubleshooting and debugging practices

For one of our projects, we needed to improve the current content delivery system for terminals. In this talk, I will share our experience in building an efficient data replication system for thousands of terminals. We will touch on architecture decisions and tradeoffs, technologies that we used, and a bit of load testing.

LUNs are provided by the Storage systems. LUNs are treated as Managed Disks in SVC. There is a 1:1 relationship between storage system LUN and mdisk. Mdisks are grouped into logical groups called Managed Disk Groups. The smallest logical unit of mdisk storage is called an extent. The extents in a managed disk are pooled into the managed disk group. Vdisks are created from extents. They are assigned to hosts.

When a Fibre Channel network becomes congested, the FC switches will instead stop accepting additional frames until the congestion clears, in addition to occasionally dropping frames. This congestion quickly moves “upstream” and clogs the end devices (such as the SVC) from communicating anywhere, not just the congested links. (This is referred to in the industry as head-of-line blocking. ) This could have the result that your SVC will be unable to communicate to your disk arrays or mirror write cache because you have a single congested link leading to an edge switch. This is why SVC only supports SVC inter-node links and SVC to controller links within the same high-speed backplane of a single switch.
Application Configuration issues such as improper installation or application caching issues can introduce significant latency. Design issues can lead to single threaded application components such as serialized I/O streams. Defects in the application can cause performance issues, delays, time outs, etc Poorly tune SQL can lead to significant delays Host Multi-pathing software must be supported to ensure proper load balancing and redundancy HBA microcode and device drivers must be at supported levels to ensure connectivity/support OS must be a compatible and supported OS. SVC Microcode fixes available to improve performance – see latest microcode Front end contention – IO Group, Node port congestion, CPU contention, or cache contention Backend contention – saturated managed disk groups Backend Storage Front end port, cache or NVS contention Backend controller and disk group contention Fabric - All of the components can have design issues but the fabric design is especially important as it is imperative to avoid latency and congestion

If the SVC preferred node is not used as for communications with a host’s vdisk then a significant amount of latency is introduced due to additional svc intra-node communication. This should be avoided by properly configuring the MP software. The preferred node issue will be removed in 431 - and SVC will become fully active-active. http://www-1.ibm.com/support/docview.wss?rs=591&uid=ssg1S1002938
“ SVC 4.2 code improvements A large number of software-managed locks were modified so as to either reduce the scope of locking, reduce the duration for holding the lock, or both. The improved lock management granularity allowed some locks to be eliminated altogether, since in the new design they would have been used by only one process. Scheduling of CPU use was modified to permit greater balance of load and fewer task switches. Logic was introduced to dynamically adapt to observed MDisk stress levels, thus better matching SVC memory and processing resources to the current capability of the underlying storage.” Copyright 2007, IBM Corporation Version 9/21/2007 SVC Performance Guidelines, Section 16.2 SVC 4.2 Code Improvements
