March 2014 StorageIO Update Newsletter : Cisco Cloud, VMware VSAN and More

By Greg Schulz

Industry Trends Perspectives: Cisco Cloud and VMware VSAN

Welcome to the March 2014 edition of the StorageIO Update (newsletter) containing trends perspectives on cloud, virtualization and data infrastructure topics. Technically it is now spring here in North America and to say that we have had abnormal cold weather would be an understatement. However it is March with April just around the corner meaning plenty to do including several upcoming events (see below).

Clouds and Cisco

Some recent industry activity has included Cisco announcing its Cloud intentions (e.g. more than simply selling servers and networking hardware). So far the Cisco Cloud move appears to be more about hybrid and partner ecosystem including channels vs. going toes to toe with an Amazon Web Service (AWS). Cisco appears to playing the hybrid theme of being a technology supplier as well as provider or partner. Thus, it looks like for the near term the Cisco cloud target is not as much AWS as the likes of an IBM who recently added Softlayer or an HP.

This will also be interesting to watch where along with how other Cisco partners such as EMC, Microsoft, NetApp, VCE and VMware participate. Keep in mind that some of these and other Cisco partners also have their own public, private and hybrid cloud initiatives, services along with being a supplier to each other.

VMware VSAN Software Defined Storage

Another industry activity involving servers storage I/O networking hardware software and virtualization (aka software defined) was the general announcement (GA) by VMware of Virtual SAN (VSAN). VMware VSAN went into public beta shortly after VMworld 2013 timeframe when many of us downloaded, installed and did various types of testing with it.

For those not familiar with VSAN, it is added licensed software functionality for VMware that creates a cluster to host Virtual Machines (VMs) along with its own shared resilient storage solution (e.g. Software Defined Storage). How VSAN works is to use PCIe, SAS, SATA dedicated direct attached storage (DAS) including that are local to the VMware host server (physical machine or PM). The VMware host PMs support DAS Hard Disk Drives (HDD), Solid State Devices (SSD) including PCIe cards, drives or DIMMs, along with Solid State Hybrid Drives (SSHD). This local DAS storage is served and shared among the nodes (up to 32 host or PMs) per VSAN cluster balancing performance, availability (and resiliency) along with space capacity to host VM objects. Note that VM objects include VMDKs (e.g. virtual disks) and are not to be confused with the other type of object storage or access such as CDMI/SWIFT/S3/HTTP/REST.

VMs (and those managing them) see in the VSAN cluster datastores that are familiar with other VMware implementations including storage policies and other tools. Here is a link to a great piece by Patrick Schulz a data infrastructure systems engineer in Germany (no relation, at least not that I know of yet) where he shares his experiences with VSAN implementation.

Generic VSAN example

Instead of using an external iSCSI, Fibre Channel (FC) or FC over Ethernet (FCoE) shared SAN or NAS storage system / appliance to create the storage repository, local DAS is leveraged in groups spread across the hosts in the VSAN cluster (up to 32 nodes ). VSAN requires a percentage of SSD for each storage group on the host cluster nodes that a part is used for caching data which is persistently stored on HDD based media.

VSAN software is licensed by the number of active sockets (not the cores) in the host servers (PM) that are in the cluster or by number of VDI users (guest VMs). For example if there are four servers two with one socket and two with dual sockets there would be six socket licenses. MSRP License cost per processor socket is $2,495 USD which also assumes core VMware licenses already exist. There are also a per guest VM license of $50 per VDI instance, as well as other optional license models and bundles with different features or upgrades.

What is different with VSAN vs. other VMware clusters is that a) the storage is only accessible to VMs that are in the VSAN cluster (unless a VM exports and serves to others via NFS, iSCSI, etc which is a different conversation for another day). Another difference is that today VSAN leverage storage inside of servers or direct attached as opposed to using iSCSI, FC, FCoE SAN or NAS storage systems.

Btw, the current maximum LUN, volume or target storage device size is 4TB so if you were thinking of taking a SAS attached storage system and creating a bunch of small LUNs, you might want to review that from a cost perspective, or at least for today.

There is much more to VSAN including how it works, what it can and can not do, who it is for and whom should not use for different app's, however IMHO besides lower-end, SMB, workgroup, departmental, VMware centric environments, the number one scenario today is VDI along with where converged solutions such as those from Nutanix, Simplivity and Tintri among others are playing.

    We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
    Enthusiasm for the Internet of Things has reached an all-time high. In 2013 alone, venture capitalists spent more than $1 billion dollars investing in the IoT space. With "smart" appliances and devices, IoT covers wearable smart devices, cloud services to hardware companies. Nest, a Google company, detects temperatures inside homes and automatically adjusts it by tracking its user's habit. These technologies are quickly developing and with it come challenges such as bridging infrastructure gaps, abiding by privacy concerns and making the concept a reality. These challenges can't be addressed w...
    The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...
    The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...
    Today’s enterprise is being driven by disruptive competitive and human capital requirements to provide enterprise application access through not only desktops, but also mobile devices.
