Networking Requirements for Ethernet Scale-Out Storage (November 2018)

Scale-out storage is increasingly popular for cloud, high-performance computing, machine learning, and certain enterprise applications. It offers the ability to grow both capacity and performance at the same time and to distribute I/O workloads across multiple machines.

But unlike traditional local or scale-up storage, scale-out storage imposes different and more intense workloads on the network. Clients often access multiple storage servers simultaneously; data typically replicates or migrates from one storage node to another; and metadata or management servers must stay in sync with each other as well as communicating with clients. Due to these demands, traditional network architectures and speeds may not work well for scale-out storage, especially when it’s based on flash. In this webcast you'll learn:

  • Scale-out storage solutions and what workloads they can address
  • How your network may need to evolve to support scale-out storage
  • Network considerations to ensure performance for demanding workloads
  • Key considerations for all flash

Extending RDMA for Persistent Memory over Fabrics (October 2018)

For datacenter applications requiring low-latency access to persistent storage, byte-addressable persistent memory (PM) technologies like 3D XPoint and MRAM are attractive solutions. Network-based access to PM, labeled here PM over Fabrics (PMoF), is driven by data scalability and/or availability requirements. Remote Direct Memory Access (RDMA) network protocols are a good match for PMoF, allowing direct RDMA Write of data to remote PM. However, the completion of an RDMA Write at the sending node offers no guarantee that data has reached persistence at the target. 

This webcast outlines extensions to RDMA protocols that confirm such persistence and additionally can order successive writes to different memories within the target system. You'll learn:

  • ​Why we can't treat PM like traditional storage or volatile memory
  • What happens when you write to memory over RDMA
  • Which programming model and protocol changes are required for PMoF
  • How proposed RDMA extensions for PM would work

Centralized vs. Distributed Storage (September 2018)

In the history of enterprise storage there has been a trend to move from local storage to centralized, networked storage. Customers found that networked storage provided higher utilization, centralized and hence cheaper management, easier failover, and simplified data protection, which has driven the move to FC-SAN, iSCSI, NAS and object storage.

Recently, distributed storage has become more popular where storage lives in multiple locations but can still be shared. Advantages of distributed storage include the ability to scale-up performance and capacity simultaneously and, in the hyperconverged use case, to use each node (server) for both compute and storage. This webcast covers: 

  • Pros and cons of centralized vs. distributed storage
  • Typical use cases for centralized and distributed storage
  • How distributed works for SAN, NAS, parallel file systems, and object storage
  • How hyperconverged has introduced a new way of consuming storage

RoCE vs. iWARP (August 2018)

Network-intensive applications, like networked storage or clustered computing, require a network infrastructure with high bandwidth and low latency. Remote Direct Memory Access (RDMA) supports zero-copy data transfers by enabling movement of data directly to or from application memory. This results in high bandwidth, low latency networking with little involvement from the CPU.

This webcast examines two commonly known RDMA protocols that run over Ethernet; RDMA over Converged Ethernet (RoCE) and IETF-standard iWARP. Both are Ethernet-based RDMA technologies that reduce the amount of CPU overhead in transferring data among servers and storage systems.

Join to hear the following questions addressed:

  • Both RoCE and iWARP support RDMA over Ethernet, but what are the differences?
  • Use cases for RoCE and iWARP and what differentiates them?
  • UDP/IP and TCP/IP: which uses which and what are the advantages and disadvantages?
  • What are the software and hardware requirements for each?
  • What are the performance/latency differences of each?

FCoE vs. iSCSI vs. iSER (June 2018)

One of the features of modern data centers is the ubiquitous use of Ethernet. Although many data centers run multiple separate networks (Ethernet and Fibre Channel (FC)), these parallel infrastructures require separate switches, network adapters, management utilities and staff, which may not be cost effective.

Multiple options for Ethernet-based SANs enable network convergence, including FCoE (Fibre Channel over Ethernet) which allows FC protocols over Ethernet and Internet Small Computer System Interface (iSCSI) for transport of SCSI commands over TCP/IP-Ethernet networks. There are also new Ethernet technologies that reduce the amount of CPU overhead in transferring data from server to client by using Remote Direct Memory Access (RDMA), which is leveraged by iSER (iSCSI Extensions for RDMA) to avoid unnecessary data copying. That leads to several questions about FCoE, iSCSI and iSER covered in this webcast:

  • If we can run various network storage protocols over Ethernet, what differentiates them?
  • What are the advantages and disadvantages of FCoE, iSCSI and iSER?
  • How are they structured?
  • What software and hardware do they require?
  • How are they implemented, configured and managed?
  • Do they perform differently?
  • What do you need to do to take advantage of them in the data center?
  • What are the best use cases for each?

Everything You Wanted To Know About Storage But Were Too Proud To Ask: Part Aqua - Storage Controllers (May 2018)

Have you ever wondered what the difference was between a storage controller, a RAID controller, a PCIe Controller, or a metadata controller? What about an NVMe controller? Aren’t they all the same thing? In this webcast, our experts focus on a term that is used constantly, but often has different meanings. When you have a controller that manages hardware, there are very different requirements than a controller that manages an entire system-wide control plane. You can even have controllers managing other controllers!

This webcast covers:

  • What do we mean when we say "controller?"
  • Defining SCSI, Fibre Channel, NVMe and SDN controllers
  • How are the systems managed differently?
  • How are controllers used in various storage entities: drives, SSDs, storage networks, software-defined?
  • How controller systems work and their trade-offs

File vs. Block vs. Object Storage (April 2018)

When it comes to storage, a byte is a byte is a byte, isn’t it? One of the enduring truths about simplicity is that scale makes everything hard, and with that comes complexity. And when we’re not processing the data, how do we store it and access it? In this webcast, we  compare three types of data access: file, block and object storage, and the access methods that support them. Each has its own set of use cases and advantages and disadvantages. Each provides simple to sophisticated management of the data, and each makes different demands on storage devices and programming technologies.

Perhaps you’re comfortable with block and file, but are interested in investigating the more recent class of object storage and access. Perhaps you’re happy with your understanding of objects, but would really like to understand files a bit better, and what advantages or disadvantages they have compared to each other. Or perhaps you want to understand how file, block and object are implemented on the underlying storage systems – and how one can be made to look like the other, depending on how the storage is accessed.

Fibre Channel vs. iSCSI (January 2018)

In the enterprise, block storage typically handles the most critical applications such as database, ERP, product development, and tier-1 virtualization. The dominant connectivity option for this has long been Fibre Channel SAN (FC-SAN), but recently many customers and block storage vendors have turned to iSCSI instead. FC-SAN is known for its reliability, lossless nature, 2x FC speed bumps, and carefully tested interoperability between vendors. iSCSI is known for running on ubiquitous Ethernet networks, 10x Ethernet speed bumps, and supporting commodity networking hardware from many vendors.

Because, FCoE also delivers increasing performance as Ethernet speeds increase – and, Fibre Channel also delivers increasing performance as FC speeds increase. Historically, FC delivered speed bumps at a more rapid interval (2x bumps), while Ethernet delivered their speed bumps at a slower pace (10x bumps), but that has changed recently with Ethernet adding 2.5G, 5G, 25G, 40G, and 50G to the traditional 1G, 10G, 100G timeline. As the storage world moves to more flash and other non-volatile memory, more cloud, and more virtualization (or more containers), it’s time to revisit one of the great IT debates: Should you deploy Fibre Channel or iSCSI?

Transactional Models and Their Storage Requirements (October 2017)

One of the more important concepts in storage is the notion of transactions, which are used in databases, financials, and other mission critical workloads. In the age of cloud and distributed systems, we need to update our thinking about what constitutes a transaction. We need to understand how new theories and techniques allow us to undertake transactional work in the face of unreliable and physically dispersed systems. It’s a topic full of interesting concepts and lots of acronyms - which we promise to decode! At this webcast, you will learn:

  • A brief history of transactional systems from banking to Facebook
  • How the Internet and distributed systems have changed and how we view transactions
  • An explanation of the terminology, from ACID to CAP and beyond
  • How applications, networks & particularly storage have changed to meet these demands

Everything You Wanted To Know About Storage But Were Too Proud To Ask - Part Turquoise - Where Does My Data Go? (August 2017)

In this, the seventh entry in the “Everything You Wanted To Know About Storage But Were Too Proud To Ask” popular webcast series we look into the mysticism and magic of what happens when you send your data off. Once you click “Save,” for example, where does it actually go? 

When we start to dig deeper beyond the application layer, we often don’t understand what happens behind the scenes. In this webcast we discuss:

  • Volatile v Non-Volatile v Persistent Memory
  • NVDIMM v RAM v DRAM v SLC v MLC v TLC v NAND v 3D NAND v Flash v SSDs v NVMe 
  • NVMe (the protocol) 

Learn how these terms and concepts are at the heart of where compute, networking and storage intersect. Having a good grasp of these concepts ties in with which type of storage networking to use, and how data is actually stored behind the scenes.

Everything You Wanted To Know About Storage But Were Too Proud To Ask - Part Vermillion – What if Programming And Networking Had A Storage Baby Pod (July 2017)

In this, the sixth entry in the “Everything You Wanted To Know About Storage But Were Too Proud To Ask,” popular webcast series we look into some of the nitties and the gritties of storage details that are often assumed.

When looking at data from the lens of an application, host, or operating system, it’s easy to forget that there are several layers of abstraction underneath before the actual placement of data occurs. In this webcast we are going to scratch beyond the first layer to understand some of the basic taxonomies of these layers.

In this webcast we discuss:

  • Storage APIs and POSIX
  • Block, File, and Object storage
  • Byte Addressable and Logical Block Addressing
  • Log Structures and Journaling Systems

It’s an ambitious project, but these terms and concepts are at the heart of where compute, networking and storage intersect. Having a good grasp of these concepts ties in with which type of storage networking to use, and how data is actually stored behind the scenes.

Architectural Principles for Networked Solid State Storage Access: Part 2 (April 2017)

New solid state storage technologies are forcing the industry to refine distinctions between networks and other types of system interconnects.  The question on everyone’s mind is, when is it beneficial to use networks to access solid state storage, particularly persistent memory?  The answer to this question involves application, interconnect, memory technology and scalability factors that can be analyzed in the context of a latency budget.  A follow up to Achitectural Principles for Networked Solid State Storage, this "Part 2" webcast explores latency budgets for various types of solid state storage access.  These can be used to determine which combinations of interconnects, technologies and scales are compatible with Load/Store instruction access and which are better suited to IO completion techniques such as polling or blocking. In this webcast you’ll learn:

  • Why latency is important in accessing solid state storage
  • How to determine the appropriate use of networking in the context of a latency budget
  • Do’s and don’ts for Load/Store access

Rockin’ and Rollin’ with SMB3 (April 2017)

Server Message Block (SMB) is the core file-transfer protocol of Windows, MacOS and Samba, and has become widely deployed. It’s ubiquitous - a 30-year-old family of network code.

However, the latest iteration of SMB3 is almost unrecognizable when compared to versions only a few years old. Extensive reengineering has led to advanced capabilities that include multichannel, transparent failover, scale out, and encryption. SMB Direct makes use of RDMA networking, creates block transport system and provides reliable transport to zetabytes of unstructured data, worldwide. In this SNIA-ESF Webcast, Microsoft’s Ned Pyle, program manager of the SMB protocol, discusses the current state of SMB, including:

  • Brief background on SMB
  • An overview of the SMB 3.x family, first released with Windows 8, Windows Server 2012, MacOS 10.10, Samba 4.1, and Linux CIFS 3.12
  • What changed in SMB 3.1.1
  • Understanding SMB security, scenarios, and workloads
  • The deprecation and removal of the legacy SMB1 protocol
  • How SMB3 supports hyperconverged and scale-out storage

Everything You Wanted To Know about Storage But Were Too Proud To Ask: Part Teal – The Buffering Pod (February 2017)

Buffers, Caches and Queues are part of every data center architecture, and a critical part of performance – both in improving it as well as hindering it. A well-implemented buffer can mean the difference between a finely run system and a confusing nightmare of troubleshooting. Knowing how buffers and queues work in storage can help make your storage system shine.

However, there is something of a mystique surrounding these different data center components, as many people don’t realize just how they’re used and why. In this pod of the “Too Proud To Ask” series, we demystify this very important aspect of data center storage. You’ll learn:

  • What are buffers, caches, and queues, and why you should care about the differences?
  • What’s the difference between a read cache and a write cache?
  • What does “queue depth” mean?
  • What’s a buffer, a ring buffer, and host memory buffer, and why does it matter?
  • What happens when things go wrong?

In this part of the series, “Everything You Wanted To Know about Storage But Were Too Proud To Ask,” we focus on the network aspect of storage systems.

As with any technical field, it’s too easy to dive into the jargon of the pieces and expect people to know exactly what you mean. Unfortunately, some of the terms may have alternative meanings in other areas of technology. In this Webcast, we look at some of those terms specifically and discuss them as they relate to storage networking systems, covering: 

  • Channel vs. Bus
  • Control Plane vs. Data Plane
  • Fabric vs. Network

Clustered File Systems: No Limits (October 2016)

Today's storage world would appear to have been divided into three major and mutually exclusive categories: block, file and object storage. The marketing that shapes much of the user demand would appear to suggest that these are three quite distinct animals, and many systems are sold as exclusively either SAN for block, NAS for file or object. And object is often conflated with cloud, a consumption model that can in reality be block, file or object.

But a fixed taxonomy that divides the storage world this way is very limiting, and can be confusing; for instance, when we talk about cloud. How should providers and users buy and consume their storage? Are there other classifications that might help in providing storage solutions to meet specific or more general application needs?

This webcast explores clustered storage solutions that not only provide multiple end users access to shared storage over a network, but allow the storage itself to be distributed and managed over multiple discrete storage systems.

Everything You Wanted To Know About Storage But Were Too Proud To Ask – Part Chartreuse (September 2016)

In the first part of the webcast series, we take an irreverent, yet still informative look, at the parts of a storage solution in Data Center architectures. This webcast, Part Chartreuse, starts with the very basics – The Naming of the Parts. We break down the entire storage picture and identify the places where most of the confusion falls. You'll hear:

  • What an initiator is
  • What a target is
  • What a storage controller is
  • What a RAID is, and what a RAID controller is
  • What a Volume Manager is
  • What a Storage Stack is

With these fundamental parts, we’ll be able to place them into a context so that you can understand how all these pieces fit together. Oh, and why are the parts named after colors, instead of numbered? Because there is no order to these webcasts. Each is a standalone seminar on understanding some of the elements of storage systems that can help you learn about technology without admitting that you were faking it the whole time!

Architectural Principles for Networked Solid State Storage Access (June 2016)

There are many permutations of technologies, interconnects and application level approaches in play with solid state storage today.  In fact, it is becoming increasingly difficult to reason clearly about which problems are best solved by various permutations of these. 

In this Webcast, Doug Voigt, chair of the SNIA NVM Programming Technical Working Group, will outline key architectural principles that may allow us to think about the application of networked solid state technologies more systematically, answering questions such as:

  • How do applications see I/O and memory access differently?
  • What is the difference between a memory and an SSD technology?
  • How do application and technology views permute?
  • How do memory and network interconnects change the equation?
  • What are persistence domains and why are they important?

How Ethernet RDMA Protocols iWARP and RoCE Support NVMe over Fabrics (January 2016)

NVMe (Non-Volatile Memory Express) over Fabrics is of tremendous interest among storage vendors, flash manufacturers, and cloud and Web 2.0 customers. Because it offers efficient remote and shared access to a new generation of flash and other non-volatile memory storage, it requires fast, low latency networks, and the first version of the specification is expected to take advantage of RDMA (Remote Direct Memory Access) support in the transport protocol.

Many customers and vendors are now familiar with the advantages and concepts of NVMe over Fabrics but are not familiar with the specific protocols that support it. This Webcast explores and compares the Ethernet RDMA protocols and transports that support NVMe over Fabrics and the infrastructure needed to use them. You’ll hear:

  • Why NVMe Over Fabrics requires a low-latency network
  • How the NVMe protocol is mapped to the network transport 
  • How RDMA-capable protocols work
  • Comparing available Ethernet RDMA transports: iWARP and RoCE 
  • Infrastructure required to support RDMA over Ethernet
  • Congestion management methods

Life of a Storage Packet (Walk) (November 2015)

When we talk about “Storage” in the context of data centers, it can mean different things to different people. Someone who is developing applications will have a very different perspective than someone who is responsible for managing that data on some form of media. Moreover, someone who is responsible for transporting data from one place to another has their own view that is related to, and yet different from, the previous two.

Add in virtualization and layers of abstraction, from file systems to storage protocols, and things can get very confusing very quickly. Pretty soon people don’t even know the right questions to ask!

How do applications and workloads get the information? What happens when you need more of it? Or faster access to it? Or move it far away? This Webcast takes a step back and looks at “storage” with a “big picture” approach, looking at the whole piece and attempt to fill in some of the blanks for you as we talk about:

  • Applications and RAM
  • Servers and Disks
  • Networks and Storage Types
  • Storage and Distances
  • Tools of the Trade/Offs

The goal of the Webcast is not to make specific recommendations, but equip the viewer with information that helps them ask the relevant questions, as well as get a keener insight to the consequences of storage choices.
