    For the last five years, Hitachi Data Systems has been following a three-step vision and strategy that was defined by our CEO, Jack Domme, which he first presented at an Executive Advisory Board in August 2010. The foundation for this vision and strategy starts with a continuous infrastructure that enables the non-disruptive access to data, applications, and information over a virtualized infrastructure. The second step was a content management system for structured and unstructured data, that could scale from edge, to core, to public cloud and be accessible anywhere, any time, over any…
  • EMC’s DSSD hiring is exploding

    StorageMojo
    Robin Harris
    18 Feb 2015 | 1:24 pm
    DSSD, the Valley startup acquired by EMC last year (see EMC goes all in with DSSD) is continuing to hire at an accelerating rate. Informed sources put the current DSSD team at 160 heads with plans to grow it to 800 over the next year. This is a program in a hurry. Hiring such numbers in the very tight Silicon Valley job market today is expensive, where even new graduates command 6 figures – and need it to afford an apartment with only one roommate. But given that VMAX needs a low latency backend to replace the uncompetitive VMAX disk infrastructure, the rush is understandable. Rotating…

    Well it's Tuesday again, and you know what that means? IBM Announcements! In my previous post, [How is Software Defined different than what we have now?], I explain how software can enable self-service automation through a "Control Plane" to request IT infrastructure resources, and a "Data Plane" to provision those resources. IBM has chosen three particular Software Defined Environments. At one end, IBM is a platinum sponsor of OpenStack which supports x86 servers, POWER systems and z System mainframes. A problem with open source projects like this, however, is that…

    The System Performance Council SPC-1 tests results for Hitachi VSP G1000 have just been published on the SPC website and the results show that the G1000 is the clear leader in storage performance against the leading all flash storage arrays! VSP G1000 can be configured as an all-flash storage array simply by not adding any spinning disks. The chart above is constructed from data on the SPC-1 website which shows the audited results of the SPC -1 test that was run on different all-flash storage systems. This test consists of a single workload designed to demonstrate the performance of a storage…
  • The Advantages and Benefits of Erasure Coding in the HCP S10

    We recently announced the HCP S10 Storage node as part of our HCP portfolio of object storage solutions. See my previous post on the changes that the S10 introduced in the way that we access, manage and protect data. S10 introduced a high capacity commodity disk system with higher availability and faster rebuild times than enterprise disk systems with RAID 6 protection.  This was done through the use of erasure coding and a patented approach to rebuild. “Erasure Coding” (EC) is a method of data protection that is well known in the networking world but is relatively new in the…

  • Latency in all-flash arrays

    Robin Harris
    17 Feb 2015 | 10:04 am
    StorageMojo has been writing about latency and flash arrays for years (see The SSD write cliff in real life), with a focus on data from the TPC-C and SPC-1 benchmarks. The folks at Violin Memory asked me to create a Video White Paper to discuss the problem in a bite-size chunk. Latency is the long pole Steven Swanson’s and Adrian M. Caulfield’s work at the University of California San Diego found that with a 4Kbyte disk access, the standard Linux software stack accounted for just 0.3% of the latency and 0.4% of the energy consumption. With flash however, the same software stack…
  • EMC’s missing petabytes: the cost of short stroking

    Robin Harris
    10 Feb 2015 | 1:34 pm
    A couple of weeks ago StorageMojo learned that a VMAX 20k could support up to 2400 3TB drives, it can only address ≈2PB. Where did the remaining 5 petabytes go? Some theories were advanced in the comments, and I spoke to other people about the mystery. No one would speak on the record, but here’s the gist of the received wisdom. Different strokes for different folks Short stroking is the short and best answer. Short stroking uses the outermost tracks – the fastest, densest, and capacious tracks – to punch up drive performance. By reducing head shift time and maximizing…
  • Help StorageMojo find the VMAX 20k’s lost petabytes!

    While working on a client configuration for a VMAX 20k – and this may apply to the 40k as well, as I haven’t checked – I encountered something odd: The 20k supports up to 2400 3TB drives, according to the EMC 20k spec sheet. That should be a raw capacity of 7.2PB However, the same spec sheet appears to say that the maximum usable storage capacity – after taking care of formatting overhead, system needs, etc. is ≈2PB. Here’s the table from the spec sheet: Coming at it from other directions, it seems that since the 20k supports four 60 drive enclosures per rack,…
  • Facebook on disaggregation vs. hyperconvergence

    Robin Harris
    6 Jan 2015 | 10:04 am
    Just when everyone agreed that scale-out infrastructure with commodity nodes of tightly-coupled CPU, memory and storage is the way to go, Facebook’s Jeff Qin, a capacity management engineer – in a talk at Storage Visions 2015 – offers an opposing vision: disaggregated racks. One rack for computes, another for memory and a third – and fourth – for storage. The rationale: applications need different amounts of each resource over time. Having thousands of similarly configured servers ignores this fact and leads to substantial – at FB scale – waste.

    Over the last few days, I’ve been experimenting with Docker, Registrator, and Consul in an effort to explore some of the challenges involved in building a robust containerized infrastructure. While I haven’t finished fully exploring the idea (and documenting what I’ve learned), I did discover one interesting—and unexpected—interaction. Here’s a quick overview of my testing environment: I used two OpenStack Heat templates to spin up two clusters of 5 instances each. The first cluster is a set of CoreOS Linux instances, customized via cloud-init to not run etcd. These instances are…

    I’ve written about CoreOS a fair amount (see here, here, and here), but one of the things that is both good and bad about CoreOS is the automatic update mechanism. It’s good because you know your systems will stay up to date, but it’s bad if you haven’t taken the time to properly address how automatic updates will affect your environment (for example, you’ve manually started some Docker containers instead of using systemd unit files—when the CoreOS system reboots after an update, your Docker containers will no longer be running). Re-architecting your environment to fully account…

    Jerome M. Wendt
    25 Feb 2015 | 3:00 am
    n the early 2000’s I was a big believer in appliance and/or controller-based storage virtualization technology. To me, it seemed like the most logical choice to solve some of the most pressing problems such as data migrations, storage optimization and reducing storage networking’s overall management complexity that were confronting the deployment of storage networks in enterprise data centers. Yet here we find ourselves in 2015 and, while appliance and storage control-based storage virtualization still exists, it certainly never became the runaway success that many envisioned at the time.

    Features such as automated storage tiering and storage domains on today’s enterprise storage arrays go a long way toward making it feasible for organizations to successfully host multiple applications with different performance and priority requirements on a single array. However prioritizing the order in which data and I/Os are tiered is an entirely differently matter as organizations typically want the data and I/Os associated with their mission and business critical I/Os serviced ahead of lower priority applications. This is where the Quality of Service (QoS) Plus feature found on the…

    9 Feb 2015 | 10:46 am
    Greg “EtherealMind” Ferro recently “mused” that it might be a good idea to replace PCI Express (PCIe) inside servers or rack-scale infrastructure with Ethernet. But this seems to be the exact opposite of the direction the industry is headed.

  • vSphere 6: NFS 4.1 Finally Has a Use?

    Stephen
    3 Feb 2015 | 6:01 pm
    Way back in the 1990’s, UNIX admins delighted in upgrading from NFSv2 to NFSv3. Then NFSv4 came around and … crickets. Now VMware has become the first major/useful/mainstream application for NFSv4.1, so the floodgates are open! But are they? A Little History A long, long time ago, when Sun was the dominant server company and x86 was still a desktop CPU, computers needed to share files with each other over the network. Sun, being the dominant server company, created a networked file system called, surprisingly, Network File System or NFS for short. Like most things, it took a…
  • NexGen Storage is Back!

    Stephen
    13 Jan 2015 | 10:42 am
    When NexGen Storage was acquired by Fusion-io, industry analysts scratched their heads and tried to figure out why the PCIe flash darling wanted them. But when flash maker SanDisk acquired Fusion-io, most assumed that was the end of ioControl (neé NexGen). Then something odd happened last week: SanDisk announced a spin-out of the surviving, thriving NexGen Storage. John Spiers and company somehow landed on their feet again! NexGen Storage announced their acquisition by Fusion-io at Storage Field Day 3 on April 24, 2013 LeftHand to NexGen to Fusion-io to SanDisk The so-called hybrid…
  • Why Big Disk Drives Require Data Integrity Checking

    Stephen
    19 Dec 2014 | 3:11 pm
    Hard disk drives keep getting bigger, meaning capacity just keeps getting cheaper. But storage capacity is like money: The more you have, the more you use. And this growth in capacity means that data is at risk from a very old nemesis: Unrecoverable Read Errors (URE). You might think RAID is for data protection, but it does nothing of the sort! Let’s get one thing out of the way from the start: The only thing protecting your data from corruption is some simple error checking on the disk drive itself and anything built into the software stack on your array or server.

  • Musing: Could We Replace Ethernet With PCIe?

    Stephen
    9 Feb 2015 | 10:46 am
    Greg “EtherealMind” Ferro recently “mused” that it might be a good idea to replace PCI Express (PCIe) inside servers or rack-scale infrastructure with Ethernet. But this seems to be the exact opposite of the direction the industry is headed. Rather than replacing PCIe with Ethernet, companies like Intel seem set on replacing short-range Ethernet (in rack-scale systems) with PCIe! PCIe vs. Ethernet Greg points out (rightly) that electrical signals copper traces on motherboards are currently limited to 15.75 Gbps in PCIe 4.0. With 16 lanes, this brings us to 252 Gbps…

  • The Rack Endgame: Open Compute Project

    Stephen
    17 Sep 2014 | 11:00 am
    On reading my thoughts about the evolution of enterprise storage, culminating in what I called “The Rack Endgame” where a rack of storage, networking, and compute becomes a the basic entity of the datacenter, many pointed out that this looks an awful lot like the Facebook-led Open Compute Project (OCP). This is entirely intentional. But OCP is simply one expression of this new architecture, and perhaps not the best one for the enterprise. The Open Compute Project has developed a standard for “Endgame” rack infrastructure Hyperscale Versus Enterprise Years ago, companies like…
  • Cisco’s Trojan Horse

    Stephen
    15 Sep 2014 | 1:00 pm
    Industry watchers like me have long wondered when Cisco will transform itself into a full-line IT infrastructure vendor. This strategy was tipped in 2009 as Cisco barged into the server market with UCS. But one leg of the stool is still missing: Storage remains the province of Cisco partners like EMC and NetApp. The Rack Endgame I recently wrote about “The Rack Endgame”, a serious challenge to the enterprise storage status quo in which the current datacenter architecture with centralized networked storage arrays is blown apart by virtualization and distributed storage. It’s worthwhile…

    More and more people seem to think that we are moving to some kind of bimodal storage environment where all your active data sits on AFA and everything else in an object store. Or as I like to think of it; your data comes rushing in as an unruly torrent and becomes becalmed in a big data swamp which stinks up the place; it then sits and rots for many years, eventually becoming the fuel that you run your business on and leads to the destruction of the planet due to targeted advertising of tat that people simply must have! So just say No to Flash and No to Object Storage!
  • What Year Is This?

    4 Mar 2015 | 5:47 am
    I had hoped we’d moved beyond the SPC-1 benchmarketing but it appears not. If you read Hu’s blog; you will find that the VSP G1000 is the clear leader in storage performance against the leading all flash storage arrays! But when you look at the list, there are so many flash arrays missing from the list that it is hardly worth bothering with. No Pure, no Solidfire, no Violin and obviously no EMC (obviously because they don’t play the SPC game). Now, I haven’t spoken to the absentees whether they intend to both with the SPC benchmarketing exercise; I suspect most…

    So I know it’s a bit late notice however after a conversation in a pub last week; it has been suggested that we need another #storagebeers event and a pretty good opportunity has presented itself. It is Cloud Expo next week (March 11th – March 12th) at the Exhell Centre. So for those of you interested, we have decided that on the evening of March 11th; there will be a #storagebeers. It is possible that there will be a number of vendors in attendance and there might be a possibility of the odd sponsored beer. Normal #storagebeers rules are in force; anyone is welcome. All normal…

    If in doubt rebrand…have IBM completely run out of ideas with their storage offerings? The Spectrum rebrand of their storage offerings feels like the last throw of the dice. And it demonstrates the problems that they currently have. In fact, it is not all of their storage offerings but appears to be the software offerings? DS8K for example is missing from the line-up but perhaps Spectrum Zombie – the Storage Array that Will Not Die was a step too far. We do however have Spectrum Virtualise; this is a hardware offering offering in the form of SVC currently but is this going to…
