10 Leading All-Flash Storage Vendors - Page 2

Hitachi Data Systems

Hitachi Data Systems (HDS) is another vendor that sits in the Leaders quadrant. The HDS Virtual Storage Platform (VSP) includes the VSP F400, F600, F800 and the newest F1500. Late last year, it also brought in 14 TB flash modules. This doubled the amount of raw storage capacity. At the same time, it dropped the Hitachi Flash Storage (HFS) A-series line.

According to Gartner, HDS has high satisfaction, support and quality ratings. The VSP line comes with array software included. But its advanced software package, including Hitachi Data Instance Director (HDID) application-aware copy management, is sold at a premium. Standard features include block and file protocols, file deduplication and storage virtualization.

“Unlike most storage vendors that need a storage gateway, the HDS VSP F series natively integrates with Amazon Web Services (AWS) S3, Microsoft Azure and private cloud solutions on Hitachi Content Platform, and enables automatic migration of file data to these platforms,” said Filks.


The Kaminario K2 Gen6 is a scale-up and scale-out all-flash storage system that is said to support flexibility, performance and cost efficiency. Performance scales to over 1.5 million IOPS and more than 25 GB/sec throughput at low latency. The K2 has adaptive block size technology that enables support for mixed workload environments (such as analytics and transactional processing running at the same time). It also supports 87.5 percent utilization RAID and has inline global and selective deduplication, as well as inline byte-aligned compression. It is run by the Kaminario VisionOS distributed storage software stack. This includes enterprise data services for tier 1 storage, such as replication, snapshots, management and non-disruptive operations.

Kaminario recently announced Kaminario K2.N and Flex. K2.N is based on VisionOS with an NVMeF backend and optional front end. This makes it possible to disaggregate capacity and compute to allow more flexibility in how storage is provisioned. Kaminario Flex is a storage management and orchestration layer managing K2.N resource pools to compose virtual private arrays. It is driven by the Kaminario analytics platform Clarity. K2.N and Flex will be available in the first and second half of 2018 respectively.

Kaminario believes that the next-generation storage paradigm will be ruled by having the right software storage stack to meet the needs of next-generation applications. That means supporting extreme flexibility and performance at scale while maintaining cost efficiency and delivering a full set of data services. Any such platform must continually adopt the latest hardware and deliver it in a seamless integrated way to the customers. It touts its VisionOS as a way to achieve this.

“Kaminario is focused on the SaaS, online, business and private cloud market,” said CTO Eyal David. “These customers have the need for the scalability, performance and agility that our platform provides.”

Gartner classified Kaminario as a Leader. It gave the company credit for adding an NVMe/PCIe-connected compression offload engine, which is ready for more NVMe and NVMe fabric features as they are developed. In particular, Gartner noted that Kaminario has technological NVMe leadership and execution.


Gartner classifies Tegile as a Visionary in the bottom right quadrant. It earned that label due to the fact that many of the guarantees, purchase options, features and programs that Tegile offers cannot be matched by competitors.

“The interoperability, flexibility of options and features of the Tegile arrays are probably the most extensive in the market,” said Filks. “The arrays offer unified protocol support, very detailed instrumentation and configuration flexibility.”

The Tegile IntelliFlash HD is aimed at medium and large enterprises. It is said to deliver up to five million IOPS and 10 PB of effective capacity in a rack. It can be used to consolidate mixed workloads into a single platform.

Additionally, the company just updated its all-flash product line for the NVMe market, Gartner expects to be worth more than $50 billion by 2020 due to the demand for speed and performance. The Tegile N Series all-flash storage arrays incorporate solid state media with NVMe technology (24 HGST Ultrastar NVMe SSDs in a 2U footprint). This can offer up to 3 million IOPS with consistent 200 microsecond latency.

“With the introduction of NVMe to the market, the next major battle in the enterprise storage market will be fought in the realm of persistent memory storage,” said Rohit Kshetrapal, CEO of Tegile.


Tintri didn’t make it into the Leaders quadrant, but it did meet it into the Visionaries section. Filks noted that Tintri’s focus is on server-virtualized environments. With a new IPO behind it, Tintri is expanding.

On the product front, it has announced plans for a product refresh and larger arrays later in the year. Currently, there are three T5000 series models available: T5040, T5060 and T5080. They scale from 6 TB at the low end to 92 TB of raw capacity at the top. Expect those numbers to shift significantly when the new models come out.

The company claims up to 30:1 data reduction numbers. The Tintri SSAs also have hypervisor integration, simple administration and provisioning, as well as deep integration with VMware, Microsoft Hyper-V and OpenStack. On the downside, there is no support for block storage or physical hosts.


Gartner classes Fujitsu as a Challenger when it comes to all-flash storage. The Fujitsu ETERNUS AF storage product line is said to be affordable and easily configurable. It has an automated quality of service feature to ensure each application gets the performance it needs. Deduplication and compression are included, as well as disaster recovery (DR), mirroring and automated transparent failover. The ETERNUS AF line consists of two models: the entry-level ETERNUS AF 250 (>700 TB SSD capacity) and the midrange ETERNUS AF650 (up to 3 PB of SSD capacity).

“The key differentiators of Fujitsu ETERNUS AF systems are response time, flexible deduplication and compression, automated quality of service management and transparent failover,” said Frank Reichart, head of storage marketing at Fujitsu. “If an ETERNUS AF system goes down, an ETERNUS AF or DX system can take over within five seconds at another location.”

Gartner drew attention to the fact that the Eternus AF250 (with 737 TB of raw capacity) and Eternus AF650 (with 2.9 PB raw capacity) are backward compatible with earlier Fujitsu flash arrays, include good migration services from Fujitsu HDD arrays to SSAs, and have beneficial swap-out financial terms for Fujitsu-sold Violin Memory arrays.
