Qumulo tries to SoC it to nearline with Xeon D integrated systems

Range extension encroaches on Dell's Isilon territory


Scale-out clustered filer Qumulo has introduced a nearline archive product, the K-144T.

The archive box fits alongside its all-flash P-Series and hybrid flash+disk QC filers. All three run its Qumulo File Fabric (QF2) software as does its EC2 implementation in AWS and data can be continuously replicated to, from and between its on-premises and in-cloud clusters

Qumulo says it uses industry-standard hardware and offers archive pricing with nearline array access speeds.

The Nearline Archive Series is a scale-out, clusterable K-144T box featuring:

  • 1U enclosure containing 12 x 3.5-inch 12TB, 7,200rpm SATA disk drives and 3 x 800GB SSDs
  • Xeon-D SoC with D-1531 6-core, 2.2GHz cpu, 64GB integrated memory and dual 10GbitE networking
  • 144TB raw capacity
  • 2.4GB/sec reads from minimum 6-node cluster, 8 GB/sec from 20-node cluster
  • 30GB/sec from a rack
  • 6GB/sec and 3GB/sec writes per 1PB usable capacity
  • From 6 to 1,000 node clusters
  • NFS (v3), SMB (v2.1), and REST protocols
  • Erasure coding and snapshots

The data sheet declares: "A minimum six-node cluster performs reads at 2.4GB/sec. Performance increases linearly with each node you add. For example, a twenty node configuration has an impressive 8GB/sec read performance. You can achieve read throughput of 30GB/sec in a single rack."

But that is not linear. The 6 and 20-node setups are rated at 0.4GB/sec per node while to get 30GB/sec from a rack means 0.71GB/sec with 42 nodes and 0.75GB/sec with 40. We have asked Qumulo about this implied inconsistency.

Qumulo Nearline Archive Series

Dell EMC's Isilon scale-out filer range includes the A200 and A2000 archive systems.

They come in 4U x 60-slot chassis (A200) or 4U x 80-slot box (A2000) and hold up to 480TB and 800TB/chassis respectively, with the A2000 using 10TB SATA drives and the A200 2, 4 or 8TB ones. The A2000 has a 200TB/U density, better than Qumulo's Nearline Archive series.

The Isilon boxes also have deduplication.

Qumulo claims its Nearline Archive is "the first scale-out storage solution to use high density 12TB drives and system-on-a-chip to provide unprecedented performance and economics". It hasn't provided any pricing information.

  • Carnival Cruises torpedoed by US states, agrees to pay $6m after waves of cyberattacks
    Now those are some phishing boats

    Carnival Cruise Lines will cough up more than $6 million to end two separate lawsuits filed by 46 states in the US after sensitive, personal information on customers and employees was accessed in a string of cyberattacks.

    A couple of years ago, as the coronavirus pandemic was taking hold, the Miami-based biz revealed intruders had not only encrypted some of its data but also downloaded a collection of names and addresses; Social Security info, driver's license, and passport numbers; and health and payment information of thousands of people in almost every American state.

    It all started to go wrong more than a year prior, as the cruise line became aware of suspicious activity in May 2019. This apparently wasn't disclosed until 10 months later, in March 2020.

  • India extends deadline for compliance with infosec logging rules by 90 days
    Helpfully announced extension on deadline day

    India's Ministry of Electronics and Information Technology (MeitY) and the local Computer Emergency Response Team (CERT-In) have extended the deadline for compliance with the Cyber Security Directions introduced on April 28, which were due to take effect yesterday.

    The Directions require verbose logging of users' activities on VPNs and clouds, reporting of infosec incidents within six hours of detection - even for trivial things like unusual port scanning - exclusive use of Indian network time protocol servers, and many other burdensome requirements. The Directions were purported to improve the security of local organisations, and to give CERT-In information it could use to assess threats to India. Yet the Directions allowed incident reports to be sent by fax – good ol' fax – to CERT-In, which offered no evidence it operates or would build infrastructure capable of ingesting or analyzing the millions of incident reports it would be sent by compliant organizations.

    The Directions were roundly criticized by tech lobby groups that pointed out requirements such as compelling clouds to store logs of customers' activities was futile, since clouds don't log what goes on inside resources rented by their customers. VPN providers quit India and moved their servers offshore, citing the impossibility of storing user logs when their entire business model rests on not logging user activities. VPN operators going offshore means India's government is therefore less able to influence such outfits.

    Google is winding down its messaging app Hangouts before it officially shuts in November, the web giant announced on Monday.

    Users of the mobile app will see a pop-up asking them to move their conversations onto Google Chat, which is yet another one of its online services. It can be accessed via Gmail as well as its own standalone application. Next month, conversations in the web version of Hangouts will be ported over to Chat in Gmail.
