SSDs Need Controllers with More, NO! Less Power

The Storage Developer Conference in September gave a rare glimpse into two very different directions that SSD architectures are pursuing. While some of the conference’s presentations touted SSDs with increasing processing power (Eideticom, NGD, Samsung, and ScaleFlux) other presentations advocated moving processing power out of the SSD and into the host server (Alibaba, CNEX, and Western Digital).

Why would either of these make sense?

A standard SSD has a very high internal bandwidth that encounters a bottleneck as data is forced through a narrower interface. It’s easy to see that an SSD with 20+ NAND chips, each with an 8-bit interface, could access all 160 bits simultaneously. Since there’s already a processor inside the SSD, why not open it to external programming so that it can perform certain tasks within the SSD itself and harness all of that bandwidth?

Example tasks would include Continue reading “SSDs Need Controllers with More, NO! Less Power”

Kaminario Adopts Software-Only Business Model

Kaminario recently decided to adopt a “software-centric” business model, rather than sell all-flash arrays as the company has done since its inception. The company says that this will allow it “to streamline operations, while focusing its resources on continued software innovation,” acknowledging that the change: “represents a strategic business model shift for Kaminario.”

Hardware support for existing and future Kaminario customers will be provided by Tech Data, which Kaminario’s release tells us is the world-leading end-to-end distributor of technology products, services, and solutions.

Jay Kramer of Network Storage Advisors, a friend of The SSD Guy recently provided me with some valuable insights on Kaminario’s restructuring and has allowed me to share them here. Jay is a recognized technology consultant specializing in the network storage industry.

Here’s what Jay has to say Continue reading “Kaminario Adopts Software-Only Business Model”

WDC: No SSD/HDD Crossover

Those who have been reading posts on The SSD Guy blog for some time have often heard me explain that SSD prices will not fall below HDD prices anytime soon. Last week Western Digital shared a roadmap that shows that we can expect for there to be a sizeable price gap between the two technologies at least through 2028.

Let me stop for a moment to point out that Western Digital Corp, or WDC, no longer has any reason to take sides in the HDD vs. SSD battle now that the company has acquired SanDisk, a leading SSD maker. Even before that, WDC’s HGST business has been the market leader in SAS SSDs for a number of years. WDC doesn’t take sides in arguments about SSDs vs. HDDs. Instead the company stands ready to sell whichever one the customer finally decides to use.

This post’s graphic comes from a chart that WDC used on October 11 when introducing its new MAMR head technology, which the company expects to propel HDD capacities up, and HDD price per terabyte down, for a number of years. To create this chart WDC’s HDD team joined forces with the SanDisk flash team to project both HDD and NAND price per terabyte for the next 11 years. The most important conclusion is that Continue reading “WDC: No SSD/HDD Crossover”

SanDisk Rolls Out InfiniFlash

The following post is an excerpt of an article Objective Analysis submitted to the Pund-IT Weekly Review for 11 March, 2015.

With a webcast in the style of the big system makers like EMC and Oracle, SanDisk announced its InfiniFlash flash appliance. InfiniFlash is a box that crams a whopping 500 terabytes into only 3U of rack space.

How big is 500 terabytes? It’s more bytes than SanDisk’s entire flash output for 2001.

SanDisk boasts that InfiniFlash is a “category-defining product”, and pointed to the fact that IDC, who provided support for the roll-out, created a new “Big Data Flash” storage product category for this device.

The system boasts performance of one million random-read IOPS, which is impressive, but doesn’t give much indication of how it performs in standard enterprise dataflow, which is generally assumed to consist of a 70/30 split of reads and writes. (I should mention here that Objective Analysis published a survey of users’ IOPS and latency needs which can be purchased on our website.)

Price is a major focus for this product. SanDisk says that it will sell systems bundled with software at less than Continue reading “SanDisk Rolls Out InfiniFlash”

Western Digital to Acquire sTec

The following is excerpted from an Objective Analysis Alert e-mailed to our clients on 24 June, 2013:

Western Digital Corporation (WDC) and sTec, Incorporated announced today an agreement for sTec to be acquired by WDC for $340 million in cash. The HGST subsidiary will assume control of sTec and will continue to support existing sTec products and customers, while also remaining a part of its joint development program with Intel Corp. HGST’s current line of SSDs uses an Intel controller architecture combined with an SAS interface, end-to-end data protection, and other features key to the enterprise SSD marketplace.

Although sTec was a glorious first mover in the SSD business with EMC’s Continue reading “Western Digital to Acquire sTec”

WDC’s HGST Intros 12G SAS MLC SSDs

In case you didn’t have enough abbreviations in your life, The SSD Guy brings you the headline above, with the promise that the news below is really interesting: HGST (formerly Hitachi Global Storage Technology, but now a division of WDC – Western Digital Corp.) has brought out a new line of 12Gb/s SAS SSDs based on MLC flash. These are a part of the UltraStar line.

Whereas HGST’s first-generation UltraStar SAS SSDs used SLC flash, the new SSDs are based on 25nm MLC flash but offer the same warranties as HGST’s prior generation. Even so, performance for the new SSDs is significantly faster than that of their SLC-based predecessors, with no reduction in wear or lifetime specifications.

These SSDs are the first to support Continue reading “WDC’s HGST Intros 12G SAS MLC SSDs”

The SSD Pricing Maven

When I have a question about SSD retail pricing I know exactly who to consult. Andy Higgenbotham (pictured here) and his Price G2 service track HDD and SSD retail pricing and publish data to a very high degree of resolution.

Price G2 data has been used in another post in the blog: When Will SSD Prices Drop Below HDD Prices?

This company publishes weekly reports of pricing from all major HDD and SSD manufacturers (Seagate, Western Digital, Toshiba, Samsung, Intel, Micron, and the like) with information on market trends like this for the week of April 23:

Flat to increasing pricing continues throughout 2012. Only on the 512GB have we seen sustained price drops from Q1 and through Q2. The 512GB capacity currently sells for $1.05/GB in week 17.

Amid recent rumors of steep SSD price declines this service has served to disprove any notion that the SSD market is undergoing fundamental change. The SSD Guy highly recommends Price G2 for anyone whose business relies on timely and thorough HDD and SSD price tracking.

Micron: SSD Over-Inventory at OEMs & Channel

Excess Inventory of SSDs During Micron Technology‘s quarterly earnings call an interesting tidbit was revealed: PC OEMs and Micron’s sales channel partners are carrying SSD inventory from panic buys they made in response to Thailand’s floods.

It seems that Micron’s OEMs and channel partners expected the HDD shortage that resulted from the floods to create new market opportunities for SSDs. This is not an uncommon notion, and it was first discussed by The SSD Guy in a blog post early last November with another post added in January. It seems that the messages of these posts didn’t reach those OEMs.

Micron mentioned this because Continue reading “Micron: SSD Over-Inventory at OEMs & Channel”
