14 Storage Startups Breaking New Ground


The advent of very high-performance, high-capacity SSDs, coupled with new interfaces such as NVMe over Fabrics and software-defined networking give storage a major creative boost. We are migrating from RAID systems to compact appliances that deliver storage, and, in the form of hyperconverged infrastructure (HCI) systems, compute as well.

A number of innovative storage startups are helping drive this evolution. The list of startups is growing fast and new companies appear out of stealth mode on a regular basis. These are not companies chasing existing business with a better mousetrap. Many of them have game-changing approaches to how enterprises will implement and manage storage in the future.

For some startups, the appliance and HCI models provide a standard COTS-based platform, which is essential to economies of scale and time to market. The resulting software is “portable” between platforms, with a consequently wider market opportunity, but also a tougher competitive environment.

Portability and scalability are enhanced by software-defined storage (SDS), which abstracts the code from underlying hardware platforms and operating systems. As SDS evolves —  it’s still in its early days — the agility provided by encapsulating storage microservices will create new ways to build storage software stacks, resulting in overall lower costs due to a competitive environment for each type of service.

Another focus of the current batch of storage startups is data management. Addressing data sprawl and migration between memory tiers will radically reduce storage costs, which will become critical  as we add flash/Optane tiers in the memory bus and move to all solid-state storage. Making data in disparate silos or clouds look like one pool is another issue that startups are addressing.

The challenges of replacing traditional SCSI-based networked storage to match the speed demands of solid-state drives and the performance/complexity of shared memory in the HCI model also is spawning startups. Here, the focus is on removing bottlenecks in the system and providing a mechanism for accessing the distributed storage pool. Given its complexity, this market is just emerging, but we can expect a good deal of future activity, especially with byte-addressable persistent memory on horizon.

All in all, this is a good time to be a storage startup. Click ahead to check out some of new companies worth watching as the storage industry continues its remarkable transformation.

Software-Defined Storage: 4 Factors Fueling Demand


As organizations look for cost-effective ways to house their ever-growing stores of data, many of them are turning to software-defined storage. According to market researchers at ESG, 52% of organizations are committed to software-defined storage (SDS) as a long-term strategy.

Some vendor-sponsored studies have found even higher rates of SDS adoption; while the findings are self-serving, they’re still noteworthy. For example, a SUSE report published in 2017 found that 63% of enterprises surveyed planned to adopt SDS within 12 months, and in DataCore Software’s sixth annual State of Software-Defined Storage, Hyperconverged and Cloud Storage survey, only 6% of respondents said they were not considering SDS.

What’s driving this interest in SDS? Let’s look at four important reasons why enterprises are considering the technology.

1. Avoid vendor lock-in

In an interview, Camberley Bates, managing director and analyst at Evaluator Group who spoke about SDS at Interop ITX,  said, “The primary driver of SDS is the belief that it delivers independence, and the cost benefit of not being tied to the hardware vendor.”

In fact, when DataCore asked IT professionals about the business drivers for SDS, 52% said that they wanted to avoid hardware lock-in from storage manufacturers.

However, Bates cautioned that organizations need to consider the costs and risk associated with integrating storage hardware and software on their own. She said that many organizations do not want the hassle of integration, which is driving up sales of pre-integrated appliances based on SDS technology.

2. Cost savings

Of course, SDS can also have financial benefits beyond avoiding lock-in. In the SUSE study, 72% of respondents said they evaluate their storage purchases based on total cost of ownership (TCO) over time, and 81% of those surveyed said the business case for SDS is compelling.

Part of the reason why SDS can deliver low TCO is because of its ability to simplify storage management. The DataCore study found that the top business driver for SDS, cited by 55% of respondents was “to simplify management of different models of storage.”

3. Support IT initiatives

Another key reason why organizations are investigating SDS is because they need to support other IT initiatives. In the SUSE survey, IT pros said that key technologies influencing their storage decisions included cloud computing (54%), big-data analytics (50%), mobility (47%) and the internet of things (46%).

Organizations are looking ahead to how these trends might change their future infrastructure needs. Not surprisingly, in the DataCore report, 53% of organizations said a desire to help future-proof their data centers was driving their SDS move.

4. Scalability

Many of those key trends that are spurring the SDS transition are dramatically increasing the amount of data organizations need to store. Because it offers excellent scalability, SDS appeals to enterprises experiencing fast data growth.

In the SUSE study, 96% of companies surveyed said they like the business scalability offered by SDS. In addition, 95% found scalable performance and capacity appealing.

As data storage demands continue to grow, this need to increase capacity while keeping overall costs down may be the critical factor in determining whether businesses choose to invest in SDS.

Software-Defined Storage Products: IT Pros Offer Insight


Find out what users have to say about products in the emerging SDS market.

Software-defined storage promises two very attractive benefits to the enterprise: flexibility and lower cost. But how can IT pros know which software-defined storage (SDS) product will best meet the needs of their business?

Peer reviews published by real users can facilitate their decision-making with user feedback, insight, and product rankings that collectively indicate which products are in the lead.

Based on our real user reviews at IT Central Station, these products are some of the top choices for software-defined storage today.

Nutanix

A senior system engineer said, “The support we get from Nutanix is easily the best from all vendors we work with. If you open a case you directly speak to an engineer which can help quickly and efficiently. Our customers sometimes open support cases directly (not through us) and so far the feedback was great.”

However, a CTO at an IT consulting firm said while Nutanix has the ability to connect to Azure or AWS for storing backups, he would like to have the capability to spin up a backup on Azure or AWS for disaster-recovery purposes.

“Right now, you can only send a backup to either Azure or AWS. We would like to take a backup and spin it up to an actual server that could be connected to by users from the outside,” he added.

Here are more Nutanix reviews by IT Central Station users.

VMware vSAN

A senior systems administrator and storage specialist in the government sector said he finds that vSAN allows for very easy administration. “The fact that you don’t have LUNs to set up and assign is great. The ability to set up storage policies and assign them at the disk level is also a great part of this product,” he said. “You can allow for different setups for different workload requirements.”

A senior manager of IT infrastructure noted that “The vSAN Hardware Compatibility List Checker needs to improve, since currently it is a sore point for vSAN. You need to thoroughly check and re-check the HCL with multiple vendors like VMware, in the first instance, and manufacturers like Dell, IBM, HPE, etc., as the compatibility list is very narrow. I would definitely be happy if there is significant additional support for more models of servers from Dell, IBM, HPE, etc.”

HPE StoreVirtual

A network engineer at a tech service firm reported that “Shelf level-redundancy is one of the big things that StoreVirtual has had before some other SAN manufacturer or SAN model brands, which is pretty nice. It can be rather expensive because you are much less efficient when you have that redundancy, but it’s definitely a benefit if you really need access to that data.

But a solutions engineer at an insurance company said the product’s user interface needs to be updated. “It’s getting kind of long in the tooth, and the user interface makes it look a lot more complex than it actually is to manage, and I think that you can mask a lot of that with a refresh of the user interface. While HPE has created a new HTML5 UI for the HyperConverged 380, it is not available to the rest of the StoreVirtual population.”

Dell EMC ScaleIO

An engineer at a tech vendor that is both a customer and partner with Dell EMC likes the ScaleIO user interface. “EMC has been working with storage for a long time. Therefore, they know how to clearly present any important data, including data flow and each drive’s IOPS/bandwidth; and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects. It controls them, as well as maintaining them well.”

He added that “If they could introduce a write cache feature, the product would be perfect overall.”

7 Ways to Secure Cloud Storage


Figuring out a good path to security in your cloud configurations can be quite a challenge. This is complicated by the different types of cloud we deploy – public or hybrid – and the class of data and computing we assign to those cloud segments. Generally, one can create a comprehensive and compliant cloud security solution, but the devil is in the details and a nuanced approach to different use cases is almost always required.

Let’s first dispel a few myths. The cloud is a very safe place for data, despite FUD from those who might want you to stay in-house. The large cloud providers (CSPs) maintain a tight ship, simply because they’d lose customers otherwise. Even so, we can assume their millions of tenants include some that are malevolent, whether hackers, government spies or commercial thieves.

At the same time, don’t make the common assumption that CSP-encrypted storage is safe. If the CSP uses drive-based encryption, don’t count on it. Security researchers in 2015 uncovered flaws in a particular hard drive product line that rendered the automatic encryption useless. This is lazy man’s encryption! Do it right and encrypt in the server with your own key set.

Part of the data security story is that data must maintain its integrity under attack. It isn’t sufficient to have one copy of data; just think what would happen if the only three replicas of a set of files in your S3 pool are all “updated” by malware. If you don’t provide a protection mechanism for this, you are likely doomed!

We are so happy with the flexibility of all the storage services available to us that we give scant consideration to what happens to, for example, instance storage when we delete the instance. Does it get erased? Or is it just re-issued? And if erasure is used on an SSD, how can we get over the internal block reassignment mechanism that just moves deleted blocks to the free pool? A tenant using the right software tool can read these blocks. Your CSP may have an elegant solution, but good governance requires you to ask them and understand the adequacy of the answer.

Governance is a still-evolving facet of the cloud. There are solutions for data you store, complete with automated analysis and event reporting, but the rise of SaaS and all the associated flavors of as-a-Service leaves the question of where your data is, and if it is in compliance with your high standards.

The ultimate challenge for cloud storage security is the human factor. Evil admins exist or are created within organizations and a robust and secure system needs to accept that fact and protect against it with access controls, multi-factor authentication, and a process that identifies any place that a single disgruntled employee can destroy valued data. Be paranoid; it’s a case of when, not if!

Let’s dig deeper into the security challenges of cloud storage and ways you can protect data stored in the cloud.

Enterprise Data Storage Shopping Tips


Enterprise data storage used to be an easy field. Keeping up meant just buying more drives from your RAID vendor. With all the new hardware and software today, this strategy no longer works. In fact, the radical changes in storage products impact not only storage buys, but ripple through to server choices and networking design.

This is actually a good news scenario. In data storage, we spent much of three decades with gradual drive capacity increases as the only real excitement. The result was a stagnation of choice, which made storage predictable and boring.

Today, the cloud and solid-state storage have revolutionized thinking and are driving much of the change happening today in the industry. The cloud brings low-cost storage-on-demand and simplified administration, while SSDs make server farms much faster and drastically reduce the number of servers required for a given job.

Storage software is changing rapidly, too. Ceph is the prime mover in open-source storage code, delivering a powerful object store with universal storage capability, providing all three mainstream storage modes (block-IO, NAS and SAN) in a single storage pool. Separately, there are storage management solutions for creating a single storage address space from NVDIMMs to the cloud, compression packages that typically shrink raw capacity needs by 5X, virtualization packages that turn server storage into a shared clustered pool, and tools to solve the “hybrid cloud dilemma” of where to place data for efficient and agile operations.

A single theme runs through all of this: Storage is getting cheaper and it’s time to reset our expectations. The traditional model of a one-stop shop at your neighborhood RAID vendor is giving way to a more savvy COTS buying model, where interchangeability of  component elements is so good that integration risk is negligible. We are still not all the way home on the software side in this, but hardware is now like Legos, with the parts always fitting together. The rapid uptake of all-flash arrays has demonstrated just how easy COTS-based solutions come together.

The future of storage is “more, better, cheaper!” SSDs will reach capacities of 100 TB in late 2018, blowing away any hard-drive alternatives. Primary storage is transitioning to all-solid-state as we speak and “enterprise” hard drives are becoming obsolete. The tremendous performance of SSDs has also replaced the RAID array with the compact storage appliance. We aren’t stopping here, though. NVDIMM is bridging the gap between storage and main memory, while NVMe-over-Fabric solutions ensure that hyperconverged infrastructure will be a dominant approach in future data centers.

With all these changes, what storage technologies should you consider buying to meet your company’s needs? Here are some shopping tips.
