NetApp shrinky-dinks ONTAP 9: Will support 4:1 data reduction

Never mind our latest results, gaze at our petabyte-gobbling flash racks


NetApp has re-engineered Data ONTAP, its main, FAS array operating system, to make better use of flash storage, and operate across software-only and cloud deployments to form what NetApp calls a data fabric.

The upgrade from Data ONTAP v8 is called ONTAP 9, and NetApp says it is a simpler system to operate, claiming it can be deployed and serving data in as few as 10 minutes.

NetApp says that ONTAP 9 is for mixed workload environments, from primary block and file data, to nearline and longer-term retention. It retains its scale-up and scale-out (clustering) features.

ONTAP 9 was mentioned in NetApp's latest earnings call. NetApp has shown us the main picture and know customers will be able to consume ONTAP 9 in three ways:

  • On-premises (NetApp-engineered) FAS array use
  • ONTAP Cloud for public cloud use (AWS we understand with Azure following)
  • In SW-only form as ONTAP Select, described as cost-effective

Basic Data Fabric ONTAP 9 scheme

ONTAP 9 supports 15TB SSDs, which hold half as much data again as the largest disk drives available, the 10TB drives. NetApp says it is the first flash array provider to support such large capacity flash storage; surely only a temporary advantage.

The new OS also features a guaranteed data efficiency reduction of 4:1, effectively turning a 15TB SSD into a 60TB storage space. On our calculations a 2U drive tray filled with, say, 24 x 15TB SSDs will hold 360TB. The 4:1 data reduction takes that to 1,440TB or 1.4PB. NetApp mentions more than 1PB of data in a single shelf of storage.

The capacity calculating mind boggles; a rack of 20 such trays will hold 28.8PB, which makes today's data centre disk-based storage estates look grossly bloated in physical space terms, and in power and cooling needs.

The data reduction comes with a FlashAdvantage 3-4-5 program, and is based on new and patented inline data compaction, which is better than, NetApp says, existing compression and deduplication. It makes its all-flash FAS arrays "extremely cost-effective compared to hard disk drive-based systems" which we understand to mean having at least a lower total cost of ownership (TCO), and possibly lower priced on a $/TB acquisition basis after data reduction as well.

The 3-4-5 aspects mean:

  • 3X guaranteed performance – increase performance by at least 3X with NetApp all-flash storage (over disk we assume)
  • 4:1 guaranteed efficiency – reduce required usable storage capacity by at least 4:1 with NetApp all-flash storage
  • 5 ways to get started – a range of ways to make it easier for customers to adopt flash including a free risk trial, free controller upgrade program and extended warranties

ONTAP 9 has improved system monitoring, and users can centrally manage performance, capacity and data protection across their (ONTAP) IT environment, which includes third-party arrays virtualised by ONTAP, and FlexPod systems.

The RAID capability has been upgraded to triple-parity, NetApp saying customers "can achieve up to 100 times greater security against drive failures." ONTAP 9 also has expanded encryption and compliance features.

We look forward to SolidFire announcing 15TB SSD support and, perhaps, using the same data compaction technology as ONTAP 9. El Reg also wouldn't be surprised if ONTAP 9 clustering has, or will get, greater scale-out capability than its predecessor.

FAS arrays will surely receive processor upgrades in some coming refresh and they will make even better use than current FAS arrays of the expanded flash capacity in ONTAP 9. NetApp customers will surely look at ONTAP 9 and all-flash FAS with happy anticipation and NetApp sales reps and channel will have something to make them happy too. ®

  • Foxconn forms JV to build chip fab in Malaysia
    Can't say when, where, nor price tag. Has promised 40k wafers a month at between 28nm and 40nm

    Taiwanese contract manufacturer to the stars Foxconn is to build a chip fabrication plant in Malaysia.

    The planned factory will emit 12-inch wafers, with process nodes ranging from 28 to 40nm, and will have a capacity of 40,000 wafers a month. By way of comparison, semiconductor-centric analyst house IC Insights rates global wafer capacity at 21 million a month, and Taiwanese TSMC’s four “gigafabs” can each crank out 250,000 wafers a month.

    In terms of production volume and technology, this Malaysian facility will not therefore catapult Foxconn into the ranks of leading chipmakers.

  • NASA's InSight doomed as Mars dust coats solar panels
    The little lander that couldn't (any longer)

    The Martian InSight lander will no longer be able to function within months as dust continues to pile up on its solar panels, starving it of energy, NASA reported on Tuesday.

    Launched from Earth in 2018, the six-metre-wide machine's mission was sent to study the Red Planet below its surface. InSight is armed with a range of instruments, including a robotic arm, seismometer, and a soil temperature sensor. Astronomers figured the data would help them understand how the rocky cores of planets in the Solar System formed and evolved over time.

    "InSight has transformed our understanding of the interiors of rocky planets and set the stage for future missions," Lori Glaze, director of NASA's Planetary Science Division, said in a statement. "We can apply what we've learned about Mars' inner structure to Earth, the Moon, Venus, and even rocky planets in other solar systems."

  • The ‘substantial contributions’ Intel has promised to boost RISC-V adoption
    With the benefit of maybe revitalizing the x86 giant’s foundry business

    Analysis Here's something that would have seemed outlandish only a few years ago: to help fuel Intel's future growth, the x86 giant has vowed to do what it can to make the open-source RISC-V ISA worthy of widespread adoption.

    In a presentation, an Intel representative shared some details of how the chipmaker plans to contribute to RISC-V as part of its bet that the instruction set architecture will fuel growth for its revitalized contract chip manufacturing business.

    While Intel invested in RISC-V chip designer SiFive in 2018, the semiconductor titan's intentions with RISC-V evolved last year when it revealed that the contract manufacturing business key to its comeback, Intel Foundry Services, would be willing to make chips compatible with x86, Arm, and RISC-V ISAs. The chipmaker then announced in February it joined RISC-V International, the ISA's governing body, and launched a $1 billion innovation fund that will support chip designers, including those making RISC-V components.

  • FBI warns of North Korean cyberspies posing as foreign IT workers
    Looking for tech talent? Kim Jong-un's friendly freelancers, at your service

    Pay close attention to that resume before offering that work contract.

    The FBI, in a joint advisory with the US government Departments of State and Treasury, has warned that North Korea's cyberspies are posing as non-North-Korean IT workers to bag Western jobs to advance Kim Jong-un's nefarious pursuits.

    In guidance [PDF] issued this week, the Feds warned that these techies often use fake IDs and other documents to pose as non-North-Korean nationals to gain freelance employment in North America, Europe, and east Asia. Additionally, North Korean IT workers may accept foreign contracts and then outsource those projects to non-North-Korean folks.

  • Elon Musk says Twitter buy 'cannot move forward' until spam stats spat settled
    A stunning surprise to no one in this Solar System

    Elon Musk said his bid to acquire and privatize Twitter "cannot move forward" until the social network proves its claim that fake bot accounts make up less than five per cent of all users.

    The world's richest meme lord formally launched efforts to take over Twitter last month after buying a 9.2 per cent stake in the biz. He declined an offer to join the board of directors, only to return asking if he could buy the social media platform outright at $54.20 per share. Twitter's board resisted Musk's plans at first, installing a "poison pill" to hamper a hostile takeover before accepting the deal, worth over $44 billion.

    But then it appears Musk spotted something in Twitter's latest filing to America's financial watchdog, the SEC. The paperwork asserted that "fewer than five percent" of Twitter's monetizable daily active users (mDAUs) in the first quarter of 2022 were fake or spammer accounts, which Musk objected to: he felt that figure should be a lot higher. He had earlier proclaimed that ridding Twitter of spam bots was a priority for him, post-takeover.
