The past year has been a remarkable one for Open vStorage. We did 2 US roadshows, attended a successful OpenStack summit in Vancouver, moved and open-sourced all of Open vStorage on GitHub and released a lot of new functionality (our own hyperconverged backend, detailed tuning & caching parameters for vDisks, a certified OpenStack Cinder plugin, remote support, CentOS7, …). The year also ended with a bang as customers were trying to beat each other’s top 4k IOPS results.
While it might look hard to beat the success of 2015, the Open vStorage Team is confident that 2016 will be even more fruitful. Feature wise some highly anticipated features will see the light in Q1: improved QEMU integration, block devices (blktap support), docker support (Flocker), iSCSI disks, replication, support for an all-flash backend, … Next to these product features, the team will open its kimono and discuss the Open vStorage internals in detail in our new GitBook documentation. In order to be more in spirit with the open source community, blueprints of upcoming features will also be published as much as possible to the GitHub repo. A first example is the move of the Open vStorage config files to etcd. Finally, based upon the projects of partners and customers in the pipeline, 2016 will be unrivaled. So far a 39 node cluster (nearly 125TB of flash alone) is being deployed in production and multiple datacenters (US, Europe, Asia) are being transformed to use Open vStorage as storage platform.
Cheers to the New Year. May it be a memorable one.
The end of 2014 is near so it is time to look forward and see what 2015 will have to offer. Some people say there’s no point in making predictions and that it’s not worth speculating because nothing is set in stone and things change all the time in storage land. Allow us to prove these people wrong by sharing our 2015 storage predictions*:
Acceleration of (hyper-)converged platforms
Converged platforms are here to stay. Converged solutions are even the fastest growing segment for large storage vendors. But it will be players like Open vStorage who will really break through in 2015. Hyperconverged solutions showed that there is an alternative to expensive SAN or all-flash solutions by adding a software based caching layer to the host. Alas, these overhyped hyperconverged solutions are even more expensive per TB storage than an already expensive all-flash array. In 2015 we will see more solutions which unite the good of the hyperconverged appliance and the converged platform but at a significantly lower cost. Storage solutions that will be extremely hot and prove to be future proof will have to have following characteristics:
- Caching inside the (hypervisor) host: caching on SSD or PCIe flash should be done inside the host and not a couple of hops down the network.
- Scalability: all-flash will continue to be a waste of money due to the huge cost of flash. It is better to go for a Tiered solution: Tier 1 on flash, Tier 2 on scalable, cheap (object) storage. In case the Tier 1 and Tier 2 storage are inside the same appliance (hyperconverged), your scalability and flexibility will be limited. A much better solution is to keep the 2 Tiers completely separate in a different set of appliances but managed by the same software layer.
- Open and programmatically: storage silo’s should in 2015 be something of the past. Integration and openness should be key. Automation will be one of the hottest and most important features of a storage solution.
It should not come as a surprise that Open vStorage checks all of the above requirements.
OpenStack will dominate the cloud in 2015
This is probably the most evident prediction. During the OpenStack conference in Paris it was very clear that OpenStack will dominate the cloud the next few years. In 2014 some new kids showed support for OpenStack such as VMware (they understand that hypervisor software is now a commodity and that the data center control plane has become the high-margin battle arena). With VMware releasing their own OpenStack distribution the OpenStack distribution battlefield will be crowded in 2015. We have RedHat, Ubuntu, Mirantis, HP, VMware and many more so it is safe to say that some consolidation will happen in this area.
A new OpenStack battlefield that will emerge in 2015 will be around OpenStack storage. Currently this area is being dominated by the traditional arrays but as the software-defined storage solutions gain traction, solutions such as Open vStorage will grab a huge market share from these traditional vendors. They can compete with these SANs and all-flash arrays as they offer the same features and have the benefit of a much lower cost and TCO. While they maybe not top the total revenue achieved by the big vendors, they will definitely seize a large share of the OpenStack storage market.
If we add the fact that the Chinese government is promoting OpenStack and open-source in general, you can bet your Christmas bonus on the fact that open-source (OpenStack) storage projects (Swift, Open vStorage, …) will be booming next year. These projects will get a lot of support from Chinese companies both in adoption and development. It will be essential for traditional high-tech companies and countries not to miss the boat as once it has left the harbor it will be very hard to catch up.
New markets for object storage vendors
2015 will be the year where object storage will break out of its niche market of large video or object repositories. This has been said for many years now but 2015 will be THE year as many companies have started to realize which benefits they achieved by implementing their first object storage projects. The next target for these enterprises is to make better use of their current object storage solution. Changing all of their legacy code will not happen in 2015 as this might impact their business. Solutions where they don’t have to change their existing code base and still benefit from the cost saving of object storage will be selected. Open vStorage is one of those solutions but we are pretty sure other solutions like for example storage gateways to object storage will flourish in 2015.
Another reason why object storage vendors will enter new markets is because currently too many players are after the same customer base. This means that if they want to keep growing and provide ROI for the venture capital invested, new markets will definitely need to be addressed. The 15-25 billion dollar SAN market is a logical market to address. But entering this market will not be a bed of roses as object storage vendors have no experience in this highly-competitive market or sometimes not even the right sales competencies and knowledge. They will have to look for partnerships with companies such as CloudFounders who are seasoned in this area.
Seagate Kinetic drives
The Kinetic drives are the most exciting, fundamental change in the storage industry in several years. These drives went GA at the end of 2014 but in 2015 we will gradually see new applications and solutions who make use of this technology. With these IP drives, you will, for the first time, be able to manage storage as a scalable pool of disks. Open vStorage will support the Kinetic drives as Tier 2 backend. This means Virtual Machine will have their hot data inside the host on flash and their cold data on a pool of Kinetic drives.
* We will look back on this post at the end of 2015 to see how good we scored.
