Hi [[ session.user.profile.firstName ]]

Everything You Wanted To Know about Storage But Were Too Proud To Ask: Buffering

Buffers, Queues, and Caches, oh my! Buffers 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’re going to be demystifying 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?

These are just some of the topics we’ll be covering, and while it won’t be exhaustive look at buffers, caches and queues, you can be sure that you’ll get insight into this very important, and yet often overlooked, part of storage design.

    Judy Furlong, Dell Technologies; J Metz, Rockport Networks
    In order to effectively use cryptography to protect information, one has to ensure that the associated cryptographic keys are also protected. Attention must be paid to how cryptographic keys are generated, distributed, used, stored, replaced and destroyed in order to ensure that the security of cryptographic implementations are not compromised.

    This webinar will introduce the fundamentals of cryptographic key management including key lifecycles, key generation, key distribution, symmetric vs asymmetric key management and integrated vs centralized key management models. Relevant standards, protocols and industry best practices will also be presented.

  • Storage Networking Security Series – Encryption 101 Recorded: May 20 2020 60 mins
    Judy Furlong, Dell Technologies; Ed Pullin, Intel; Alex McDonald, NetApp
    Encryption has been used through the ages to protect stored secrets, authenticate messages, communicate secretly in broad daylight, and even to check that messages were properly transmitted and received without tamper. Now, it’s often our first go-to tool for making sure that data simply isn’t readable to prying eyes, ears or AI bots.

    But how does encryption actually work, what makes it tick, and how is it managed? How do we ensure compatibility? How do we protect the keys; i.e., “Who will guard the guards themselves?”

    It’s a big topic that we’re breaking down into three parts: Encryption 101, Key Management 101, and Applied Cryptography.

    Join us on May 20th for the first encryption webcast: Storage Networking Security: Encryption 101 where security experts will cover:

    •A brief history of Encryption
    •Cryptography basics
    •Definition of terms – Entropy, Cipher, Symmetric & Asymmetric Keys, Certificates and Digital signatures, etc.
    •Introduction to Key Management

    Next-Generation Networking [Ep.5]: The New WAN Economics

    Enterprise WAN traffic patterns are shifting. The application mix is changing. And the WAN is becoming core to digital transformation (and to resilience in the post-COVID-19 era).

    The two fundamental questions that network and telecom managers must answer right now are these: How much should I be spending on my WAN to achieve measurable success, and what services and solutions deliver the greatest bang for the buck (in terms of quantitative success per dollars invested)?

    This webinar shares the findings of the 2020-2021 Next Generation Networks research study and compares a cost analysis of solutions such as:
    *WAN Cloud Exchanges (WAN-CX)
    * Direct Cloud Connect (DCC)
    * MPLS
    * Carrier Ethernet
    * SD-WAN
    * Business and Broadband Internet
    * Fiber and wavelength services

    We compare the network spend by users of solutions and services from providers such as AT&T, Centurylink, Cisco, Citrix, Comcast, Juniper, Oracle/Talari, VMWare Velocloud, Verizon and others. And we correlate the spend and provider with success overall.

  • Ethernet-attached SSDs—Brilliant Idea or Storage Silliness? Recorded: Mar 17 2020 68 mins
    Mark Carlson, Kioxia; Rob Davis, Mellanox; John Kim, Mellanox; Ted Vojnovich, Lenovo
    Several SSD and networking vendors have recentl¬y demonstrated ways to connect SSDs directly to an Ethernet network. They propose that deploying Ethernet SSDs will be more scalable, easier to manage, more performant, and/or lower cost than traditional storage networking solutions that use a storage controller (or hyperconverged node) between the SSDs and the network.

    Who would want to attach SSDs directly to the network? Are these vendors brilliant or simply trying to solve a problem that doesn’t exist? What are the different solutions that could benefit from Ethernet SSDs? Which protocols would one use to access them? And how do Ethernet SSDs relate to computational storage? Join this SNIA Networking Storage Forum webcast to learn all this and more as SNIA experts discuss:

    •What are the appropriate use cases for Ethernet SSDs?
    •Why Ethernet SSDs could be appealing and more efficient
    •How Ethernet SSDs compare to other forms of storage networking
    •Different ways Ethernet SSDs can be accessed, such as JBOF/NBOF, NVMe-oF, and Key Value

    Next-Generation Networking [Ep.1] Net Win: Remaking Your Network for Next Generation Success

    Networking is undergoing a transformation. Wireless standards and services like 5G, Wifi6, LTE and Ongo are changing how wireless WANs and private networking operate. SD-WAN is driving a sea change in how WANs are provisioned and secured. Technologists are confronting emerging use cases like edge computing and IoT.

    All of these shifts are driving the need to re-architect, re-engineer, and re-think how networking is done, from private and local networks to the WAN.

    But how should they measure success? What does it mean to “successfully” redesign a network?

    This webinar delves into the operational and business success metrics for networking, and delivers the technologies and practices that correlate with that success.

    Participants will walk away with a set of usable metrics and pointers for crafting their own success strategies for next-generation networks.
  • Fibre Channel SAN Workloads Recorded: Feb 12 2020 68 mins
    Barry Maskas, HPE; Nishant Lodha, Marvell; Mark Jones, Broadcom
    Fibre Channel (FC) SAN workloads are not difficult, but there are several people who do not understand how the workloads line up to appropriate storage protocol and their characteristics. Different workloads have different “Fingerprints,” so to speak. Since FC SANs are block, they work very well with applications that have a lot of transactional data, a lot of random read/write loads, and are particularly good for virtual machine file systems.

    This webinar will discuss:
    •I/O fingerprints: I/O block sizes & IOPS requirements for various “FC SAN applications”
    •An overview of application access patterns, guided by best practices and experience
    •How FC fulfills these IOPS requirements and how CPU BW is as important as IOPS

    We will briefly investigate application sensitivity to latency, and show how protocol can affect performance.

  • The Next Generation Lossless Network in the Data Center Recorded: Jan 21 2020 57 mins
    Paul Congdon, PhD, CTO of Tallac Networks
    Modern data centers are tasked with delivering intelligent multi-media responses to real-time human interactions. Massive amounts of data are being churned and sifted by highly parallel applications, such as Online Data Intensive Services (OLDI) and Artificial Intelligence (AI), which historically required specialized High-Performance Computing (HPC) infrastructure.

    New advancements in high-speed distributed solid-state storage, coupled with remote direct memory access (RDMA) and new networking technologies to better manage congestion, are allowing these parallel environments to run atop more generalized next generation Cloud infrastructure. Generalized cloud infrastructure is also being deployed in the telecommunication operator’s central office.

    The key to advancing cloud infrastructure to the next level is the elimination of loss in the network; not just packet loss, but throughput loss and latency loss.

    There simply should be no loss in the data center network. Congestion is the primary source of loss and in the network, congestion leads to dramatic performance degradation. This presentation summaries work from the IEEE 802 Network Enhancements for the Next Decade Industry Connections Activity (Nendica).

    The Nendica report describes the need for new technologies to combat loss in the data center network and introduces promising potential solutions.
