Oh, 3PAR. One moment you're gliding along. The next, you're in the rain as HPE woos Nimble

Comment This week, HPE offered to acquire Nimble Storage for around $1.09bn, plus another $200m in share options. Nimble sells all-flash and hybrid storage solutions, with a lot of intellectual property focused around storage analytics in the form of their “InfoSight” SaaS platform. Commentators are seeing this as a good deal for both …

How Google Spanner's easing our distributed SQL database woes

Storage Architect I've been messing about with databases for a long time. I say "messing about" because I've never been a DBA, but as a systems programmer and storage administrator, I've been on the periphery of the application layer and of course I've deployed many personal databases. I was intrigued to read about the new global distributed …

Did somebody say object storage? 9 ways to tell if there's a point

Comment Object storage is a relatively new market segment that has continued to grow steadily and is starting to find more reasons for adoption. For the uninitiated, object stores are used to hold large volumes of unstructured data, where each "object" is essentially a file with no specific format (also called a binary file). Object …

Do containers stack up as data storage building blocks?

Storage Architect There’s an almost religious divide between those who see containers as entirely stateless objects and others taking a more pragmatic approach that says state and containers is an inevitable thing. In the stateless model, data is assumed to be replicated and protected by many container instances, so the loss of any individual …

A tale of two conferences: AWS storms ahead, HPE seems to flounder

The Storage Architect As we enter 2017, many people look back at 2016 and attempt to predict what might happen with technology during the coming year. The past isn't always a good reflector of the future (hence the disclaimers on many UK financial institutions' advertising). However, it does do some good to look at where we've …

VMware do we go from here?

Storage Architect VMWorld Europe was held last week in Barcelona. We saw the release of vSphere 6.5, plus a suite of other products and enhancements to the core platform. There was also the announcement of a partnership with AWS, which had many (including myself) scratching their heads as to exactly what it meant. So where is …

Bad news, Trump. NASty storage is pretty popular, too

Block-based storage (and particularly that based on Fibre Channel) has always been the favoured child when it comes to vendors talking about their products and solutions. All of the high-end performing devices tend (but not exclusively) to be block-based. However we’re seeing an increased focus on high performance NAS …

Big Mickey Dell is wrong: Cloud ain't going to eat all of IT

Storage architect Public cloud will not consume all of IT. At least that’s what Michael Dell is claiming. In his opinion, cloud will become just another form of computing and a choice will be made by users to do cloud on-premises or rent from a cloud provider. Bearing in mind Dell is in the hardware business, we can hardly expect a comment …

NetApp, storage class memory and hyper-convergence

Architecting IT blog There have been rumours that NetApp plans to move into the hyper-convergence market, followed up by The Reg's Chris Mellor here. If they are indeed true, the intention shouldn’t be a surprise in some respects. As the storage market fragments, the incumbents have to adapt to the needs of customers, and hyper-converged systems …

M.2 SSD drive format is under-rated. So why no enterprise arrays?

Blog So the latest Samsung M.2 format drives have now hit the market. In something similar to a DIMM format, you get up to 2TB of capacity and read/write speeds of 3.5Gbit/s and 2.1Gbit/s respectively. I’ve mentioned these devices in a few recent presentations as I think the potential for such small devices could be enormous. But why …

Scale-out sister? Unreliable disks are better for your storage

Storage Architect Recently I was asked to review a document that used as a reference a piece of work from Google (PDF) which talked about the need to relax the resiliency levels of hard drives and SSDs. The premise is interesting: hyper-scalers claim they could do a better job in managing performance and availability if the HDDs they use were …

Objects! Aaah-ah ... the savior of software-defined storage?

Comment Software-defined storage (SDS) is one of those terms that has been readily hijacked by vendors over the past few years. The term developed from the adoption of software-defined networking (SDN), used to define the separation of control and data traffic in the networking world, which provides the abstraction needed to deliver …

HPE sells off 'non-core' software assets

Comment On the day the Dell/EMC acquisition/merger completed, HPE announced it was selling off a load of non-core software assets in a “spin-off” merger with UK’s Micro Focus. HPE gets $2.5bn in cash and HPE shareholders will have a 50.1 per cent ownership of the new entity, which will continue to be called Micro Focus. In addition …

So Nutanix has fessed up to PernixData slurp. Now what?

So it appears the rumours were true as Nutanix finally announces the acquisition of both PernixData and calm.io, a startup focused on DevOps automation. Naturally the blog post and press release from Nutanix puts a positive spin on things, with talks of shared vision, shared ambition and a “like-spirited” approach to IT …

Enterprise storage is a stagnant – and slightly smelly – pond

Opinion Earlier this year I was at HPE Discover in Las Vegas and talking to Calvin Zito about the latest IDC Storage Tracker results. Calvin posted on the Around The Storage Block blog, covering details on both servers and storage. He highlighted the fact HPE was now ahead of EMC in terms of total Enterprise System Storage sales. Note …

Software-defined storage is glitzy, but E8 and Nimbus are still delivering hardware

Comment Despite all the recent noise around software-defined storage (SDS), vendors still keep coming to the market with new hardware solutions. Over the past weeks we’ve seen new products from Nimbus Data and emerging startup E8. Nimbus Nimbus Data has had what can only be called a ‘chequered’ history. My first introduction to the …

Gone Goel: HPE changes storage leadership

Comment It was recently reported that Manish Goel, HPE’s head of storage, had left the company. This seems to be one of a number of changes, including the departure of cloud head Bill Hilf. Although I didn’t meet him directly, Goel presented to the bloggers/influencers at the latest HPE Discover event in Las Vegas. Goel took over …

Nutanix bought PernixData to slurp caching firm's IP brains

Comment Although not officially announced, it looks like the acquisition of PernixData by Nutanix is a done deal. Confirmation came from Frank Denneman, Dutch blogger and former tech evangelist for Pernix who has now left the company. So what can we make of this? What benefit is there in taking a caching technology and adding it to …

EMC XtremIO has its quirks but rumours of its death are overblown

Comment A rumour from last week implied EMC was considering shutting down its XtremIO product line. How likely is it – and is there any basis to EMC taking this direction? The rumour seemed to come from a number of separate parties, although we can’t exclude a clever viral marketing campaign from a competitor. XtremIO history EMC …

Docker and storage – solving the problem of data persistence

In June I was in in Seattle, the home of Starbucks, Boeing and Microsoft, for DockerCon 2016. Compared to the normal events I attend, this one promises to be a more “casual” affair, so I sported polo shirts and vendor hoodies as my standard attire. One of the more interesting problems yet to be fully solved with container …

Are DataCore's SPC benchmarks unfair?

Storage Architect DataCore has been active over recent months with benchmarks based on their new SANsymphony Parallel Server offering. The most recent of these claims 5.1 million SPC-1 IOPS at $0.08/SPC-1 IOPS and 0.32 millisecond response time. Other vendors are crying foul on these results, claiming they don't represent a true test because …

SolidFire offers 'pay as you grow' deals to fight off software upstarts

Storage architect If you’ve ever had to scope out and purchase enterprise storage, you’ll know what a nightmare it can be. Vendors love to make the process as opaque as possible, with quotes that run into multiple pages and dozens of line items – including bezels and racks. Consider also the issue of adding more hardware (e.g. drives and …

Torus: Because the world needs another distributed storage software solution

The Storage Architect Last week the CoreOS project announced the release of Torus*, a scale-out storage platform for container clusters built and orchestrated by Kubernetes. At this point in the project’s development, the software isn’t production ready and still being heavily developed. Over the last few weeks, scale-out storage solutions have …

EMC Unity or VNX3? You tell me

Opinion The big announcement at the recent EMC World was VNX3 – or EMC Unity as we now have to call it. The EMC marketing Reality Distortion Field is in full effect, with the company at pains to claim that Unity is a brand new product “designed from the ground up”, although your correspondent believes it appears to be significantly …

One (storage) protocol to rule them all?

Storage Architect One of the questions posed to the “ask me anything” storage panel at this week’s TECHunplugged event was whether we will ever see a single storage protocol develop. This is an interesting idea and with the move to object storage, seems to have some merit. However, as always with technology, the answer “it depends” seems the …
