Storage news, like data growth, is unrelenting.
This week we learned of new things in the cloud, tape, new storage arrays, object storage, persistent storage for containers, cloud storage gateways, deduping to disk, and ultra-secure disk drives and SSDs. Ready? Here we go.
DataDirect Networks (DDN) has updated its WOS software to WOS Core 2.8 and WOS S3 2.3 (for the connectivity features), claiming it’s competitive cost-wise with tape for archiving. We asked if comparative numbers were available.
A DDN spokesperson said: “WOS is competitive with tape storage alternatives and gets close to the cost of tape for active archives. DDN hasn’t published figures and isn’t referring to the cost of a tape removed and on a shelf, but rather to tapes in a library with an automated method for loading tapes (a robot) and sufficient performance to be viewed as an adequate alternative.”
That’s a “No,” then.
DDN also told more about its new Extended ObjectAssure erasure coding: “Extended ObjectAssure is the application of a fairly common model for data protection for Object Storage and when combined with WOS’ existing selection of data protection options, offers the most expansive flexibility and choice in the industry.
“It builds on WOS ObjectAssure technology to provide data protection at Local ObjectAssure efficiency while providing highest availability of data. Extended ObjectAssure erasure encoding divides the object into k+m fragments, and each fragment is stored on a separate node. Data remains available when up to m fragments are available. WOS supports a wide variety of Extended ObjectAssure configurations, where:
- k is the number of data fragments
- m is the number parity fragments
- k+m is the total number of fragments stored
“This allows customers to get to very efficient overhead numbers for parity, especially for wide and deep codes for large data repositories. Offering this option alongside our existing Local Object Assure (LOA), Global Object Assure (GOA) and Replication now gives customers the ultimate ability to manage data protection based on the value of the data and the desired performance, latency, MTTDL and availability. All the data protection options are applied by policies at the object level, and can be intermixed within a cluster.”
There was an advance in S3 connectivity with the update as well, from single to multi-site connectivity. DDN said it did this because “We consistently hear about customers not being able to meet replication SLAs with S3.”
Customers can now “access the WOS repository via S3 in multiple locations, with centrally managed credentials (including integration with LDAP and Active Directory), as well as fully protect the repository in case of local outage or disaster, with the ability to failover and failback once a primary site is restored. The solution we are announcing is very high performance and will allow our customers to meet their stringent SLA for replication.”
Exagrid has released V5.0 of its deduping, disk-based backup software. It includes better support for Oracle RMAN Channels, Veeam Scale-Out Backup Repository (SOBR), and replication to AWS public cloud for disaster recovery.
Oracle RMAN customers can use RMAN Channels with up to 25 appliances in an ExaGrid scale-out GRID system, and enjoy global deduplication, for what it’s worth in that database environment. “Sections” of data are sent to each appliance in parallel for improved performance and also for performance load balancing, as RMAN Channels will send the next section of data to the next available appliance in the GRID.
Exagrid CEO Bill Andrews exclaimed: “ExaGrid v5.0 is the first backup storage solution that provides fast backups at a rate of up to 200TB/hour per PB, and fast restores with the ExaGrid landing zone coupled with performance load balancing and failover when working with Oracle RMAN.” He reckons, “There is no solution on the market that will come close to the ExaGrid approach for Oracle RMAN.”
He tells The Reg, “80 per cent of our business now comes from replacing Commvault deduplication to disk, Veritas 5200/5300 appliances, Data Domain, HP StoreOnce and Quantum DXi,” which is threatening to those suppliers if Exagrid’s business keeps on growing.
It is outpacing the deduping to disk backup market, with leader Data Domain maturing yet still unable to offer global deduplication. Exagrid reckons it could achieve an IPO in 2019, with Andrews saying: “We are heads-down focused on a 2019 IPO. We have met with many investment banking firms and know exactly what we need to do.”
Fujitsu and Oracle
Fujitsu and Oracle are offering Oracle public cloud services from a Fujitsu data center in Japan. Customers can subscribe to Fujitsu Cloud Service K5 DB powered by Oracle Cloud. The Oracle Database Cloud Service is one of the database options available from Fujitsu Cloud Service K5.
Fujitsu and Oracle formed a strategic alliance on July 6, 2016 to deliver enterprise-class cloud services to customers in Japan and their subsidiaries around the world.
A canned quote from Edward Screven, Chief Corporate Architect at Oracle, said: “By combining Fujitsu’s system integration expertise with Oracle’s cloud services, Fujitsu and Oracle will accelerate the transition of our joint customers’ enterprise systems to cloud.” Fujitsu has the largest number of Oracle-certified Oracle Cloud engineers in Japan.
This should provide a timely boost to Oracle as it focuses on growing its public cloud customer base.
Mpstor has a new all-flash array, the OSA-F60, with these features:
- 2U enclosure with 60 x 2.5-inch drive bays
- Dual, hot-swap controllers
- Up to 128GB of controller memory
- Orkestra SAM software with inline compression, deduplication and IOPS rate limiting
- Block data access over 16Gbit/s FC, 40GBitE and 56Gbit/s InfiniBand
- Access protocol support for iSCSI and ISER
- Field replaceable drives, power supplies and fans
- Validated with Red Hat Linux (RHEL) and Windows; dual controller software validated with RHEL multi-path and Windows multi-path MPIO
- The array is rated for 1.6M IOPS with 4K random reads.
We prodded Mpstor to clarify a few things about the array. Here's the results of that probe:
El Reg What is the array’s raw capacity?
Mpstor We support a total of 60x15.3TB drives in a 2U Chassis for a total RAW capacity of approx 900TB.
El Reg What CPUs do the controllers use? (including number of cores)
Mpstor We use a 10 core Intel Xeon CPU E5-2670.
El Reg 128GB DRAM per controller for the two controllers?
Mpstor We use 128GB per controller.
El Reg What is the array’s latency?
Mpstor At 1M IOPS the latency is less than 2 ms.
El Reg Why not 32Gbit/s Fibre Channel?
Mpstor We support up to 16G FC, the next version will support 32G FC.
El Reg The release says field replaceable disks but it’s an all-flash array?
Mpstor Every one of the 60 SSDs are hot swap FRU devices and user accessible.
El Reg The release says it’s “available in a range of SAN configurations including 8x8G-FC, 4x16G-FC, 4x48G-Ethernet or 4x56G-Infiniband.” but it only supports 40GbitE not 48.
Mpstor That was a typo, its 40G Ethernet.
El Reg The release says “using an automation API or conventional GUI” but there is no such thing as an automation API, only an API used for automated access.
Mpstor Correct, the OSA-F60 is delivered with a set of python CLI tools to automate the provisioning process such as RAID creation, volume creation and volume exports to hosts, as well as all monitoring functions.
El Reg An Mpstor webpage says the OSA-F60 “supports SAS expansion JBOD enclosures, expansion enclosures can be either 2Ux60 2.5-inch SSD or 4Ux60 3.5-inch HDD drive enclosures.” But it’s described as an all-flash system. Why is there disk drive support there?
Mpstor The OSA-F60 is an all flash SSD array, the OSA-F60 software can manage HDDs as well. The option is there for a user to add additional capacity either as SSD or HDD.
El Reg What's the array cost?
Mpstor The price is less than US$2.00 per GB and less than $0.50 per GB effective (assuming a conservative dedup ratio of 4:1).
El Reg Can we buy one now?
Mpstor Units are available now.
UK-based StorageOS has announced the availability of the public beta release of its software storage which delivers highly available databases in containerised apps. lt’s free to developers on the Docker Store and has recently achieved Docker Certified status for its managed volume plugin.
The StorageOS beta software has no hardware or kernel dependencies and can be installed in the cloud, in VMs, or bare metal with one command.
Deni Connor, founding analyst for SSG-NOW, thinks using containers for production is becoming more prevalent and the market will be worth $2.7 billion by 2020. Persistent storage for containers should see a rise in demand if that happens.
