Cloud integration with Cohesity storage platform

Cohesiy added Cloud integration to their secondary storage platform, featuring 3 cost-effective solutions for archival, tiering and replication. They had added a good set of features recently with their 2.0 release. Cohesity presented at Storage Field Day 9, in which they discussed their new features including the cloud integration.

If you are not familiar with Cohesity, you may read my previous post about their secondary storage consolidation.



Continue reading

CloudArchive : CloudArchive is a feature introduced recently with their version 2.0 release. This feature allows archiving data from Cohesity platform to the cloud. They are supporting Google Nearline, Microsoft Azure and Amazon S3, Glacier for archiving data for an extended period.

CloudTier : This solution helps customers to use cloud storage as a lower tier storage with their on-premise Cohesity platform. This is another cost-effective solution and enables efficient use of the local storage space by using the public cloud. It relocates data based on the defined policies and the access pattern of the data.


CloudReplicate : Setting up a Disaster Recovery solution is a real pain and is highly expensive. With CloudReplicate, Cohesity gives their customers a solution to replicate their data to public cloud storage. A cheaper solution for having a secondary copy for disaster recovery. This solution is expected to be available for production use later this year.

You may watch the cohestiy presentation at SFD9 here including a demo of their cloud solutions.

Leader, in technology and in figures that matter – all in just 2 years.

The phase of transition in data storage now is mainly anchored on 2 architectural approaches – All-Flash storage arrays as a result of the Flash domination and the second is the HCI (Hyper-Converged Infrastructure). The competition is really tough in these areas today as there are many startups and existing vendors trying their luck here.

I’ve got a chance to hear from a few of the vendors who sell their HCI solutions. Different solutions, all competing to be in the race and to have a better spot. Being the front-runner is a real tough thing, but there should be¬†One and there is One.

VMware presented at the Storage Field Day 9 in which Christos Karamanolis (CTO, Storage & Availability) discussed VSAN, it’s growth and the technology – mainly the enhancements introduced with the 6.2 release. In just 2 years, the customer base they have achieved and the feature set they have brought in are simply awesome. With an average of 500+ new customers every quarter, VSAN is now having over 3000 customers. Really HUGE numbers..!

The stats from the business displayed during the presentation (including the number of units sold and the growth rate) were impressive. Number 1, for a reason.



Figures on performance : VMware VSAN is claiming the highest performance and lowest cost with their All-Flash Hyper-Converged configurations. 100K IOPS/node with sub-millisecond latency and $1/GB for All-Flash configurations and a 40K IOPS for hybrid nodes.

VSAN 6.1 version was released in September 2015 (a release cycle of 6 months) with some good features including stretched cluster. But the biggest update announcement – 6.2 -came recently in February with another great set of features.

VSAN Stretched cluster offers site-level redundancy with a cluster spanning across 2 sites. With a max latency of 5 ms between the sites, customers can have a near-instantaneous recovery in case of site failures. Customers can replicate the datastores to a third site (probably at a longer distance) using vSphere replication. This helps the customer to have a very low RPO in the case of the metro cluster failure. The witness VM (located at a third site) for the stretched cluster configuration can now have a latency of up to 500ms.

I know you will find a lot of detailed posts on the internet on the enhancements from the 6.2 version. Still, I just thought I should outline some of them here.

Data reduction (deduplication and compression) is a great feature came with 6.2. Data will be dedupe’d and compressed at the disk group level at a 4KB block size. This feature can be enabled at the cluster level. Deduplication will be done while the data is being written to the Capacity tier from the cache tier. Compression will only be performed if the 4KB data can be reduced to 2KB or to a smaller size. Else the data will be written as a 4KB block only.

RAID 5/6 or Erasure coding¬†is another feature to improve space efficiency and level of data protection came with the February release. With mirroring being the only availability feature for datastore objects, customers were¬†compromising a lot on the space efficiency. RAID-5 now reduces the overhead requirement to 33% (from 100% for mirroring) for protecting from single drive failure. RAID-6 configuration will have a higher overhead of 50% but it can protect data against 2 drive failures (RAID-1 would have caused a 200% overhead for protecting against 2 drive failures). Customers can select from RAID 5 or 6 by selecting the ‘number of failures to tolerate’ setting (1=RAID 5 and 2=RAID 6).

One thing that disappoints many is the fact that the above 2 features are available with All-Flash configurations only.

You may read more about all these features and more (including Software checksum and disk scrubbing, QoS, Sparse Swap etc..)¬†here¬†from Duncan‘s post.

Closing notes : Many startup companies fail as they fail to find a good balance between technology and marketing. Some got a wonderful technology but are a failure in marketing the same. And that is where the VMware VSAN is winning. They added a lot many flexibilities to their product from what it was in the initial days. Also, they got a good marketing effort to ensure the maximum units are being sold.

And yes, VSAN got an edge as it is from a vendor which is named VMware.!

With these added features in 6.2, I will not be surprised to see another great set of business figures soon from VSAN.

Yesterday¬†(14-Mar), Pure Storage announced their new All-Flash products at the Pure//Accelerate event. FlashBlade is to support unstructured data (File, Object, containers etc…) requirements and FlashArray//m10 to strengthen their FlashArray//m series. FlashBlade, the cloud-scale data platform provides All-Flash efficiency and performance for their customers cost effectively.

FLASHBLADE Continue reading


FlashBlade is the industry’s first All-Flash NAS solution as per my understanding. This is a new approach from Pure to meet the next-gen requirements. Scale-out blade modules for elastic scalability. System will have only Flash modules – no SSDs and no HDDs.

Hardware : FlashBlade can have a minimum configuration of 7 blades which forms a cluster. Each blade can have 8TB or 52 TB of internal flash capacity. The flash modules are PCIe attached to the blades and they use proprietary protocol. This helps the customer to select the configuration based on their capacity requirements. In a 4U module, FlashBlade can deliver 10Gb/s and can have upto 16PB raw capacity. Blades have 40GB ethernet ports for communication between blades.


The system is now supporting only NFS protocol. SMB, Object and S3 support will be available in future releases. More data services including data reduction, snapshots etc… also will be available soon.¬†FlashBlade systems management is made easy with the Pure1 cloud-based management tool.

Availability : Early-access to the FlashBlade is now available for customers, but the systems for production will be GA towards the 2nd Half of 2016.


Flasharray m10This is new addition to the FlashArray//m models from Pure. Customers can buy a minimum configuration of 15 TB or 30TB and then grow their system as per requirement. FlashArray//m10 system can be upgraded to any of it’s big-brothers in the FlashArray//m family.

One of the attractions from the new comer is that the customers can have ‘everything’ at a starting price less than $50K. This includes all the softwares, Evergreen storage (offer from Pure to have free upgrades to add new features to the existing storage system, without the need of repurchasing the entire hardware and migrating the data). The product can also be purchased as a FlashStack CI for a starting price of nearly $100K.

DSSD D5 – EMC’s quantum leap in flash storage with the rack-scale all-flash appliance

In their ‘Quantum Leap’ announcements, alongwith VMAX All-Flash storage¬†EMC announced DSSD D5 flash appliance¬†on Monday (29-Feb). And it is really a big leap in flash storage as they produce un-matching performance¬†and capacity in small footprint. D5 is a ‘rack-scale’ flash appliance¬†for today’s today’s¬†and next-gen workloads, e.g; applications built on Hadoop.



10 Million IOPS and 100 Micro Seconds latency are real big numbers.¬†Let’s dig in more to other highlights from¬†D5 here in this post.

Continue reading

Hardware : DSSD D5 have a 5U module which with 2 redundant controllers and 36 drive slots. It can support a maximum of 144 TB of raw capacity (with 4TB flash modules). The system offers 100 TB of usable flash capacity in 5U. The system now supports 2TB/4TB (dual-ported, hot-swappable) flash modules and more in near-future.

NVMe : It’s ‘NVMe show’ with D5 as it helps the servers to have end-to-end PCIe NVMe access to the Flash modules. It is the key for providing shared flash storage via PCIe,¬†by the NVMeF (NVMe over Fabric) in use in D5. The system supports 96 ports¬†(48 ports per IO module)¬†for host connectivity. i.e, 48 hosts (PCIe3 x4 lane availability) can be directly attached with redundant connectivity. As it is end-to-end NVMe enabled, there is no overhead of protocol translation.

DSSD D5 will act as a direct attached shared flash storage for varying workloads. It’s simply direct attached Flash with enterprise availability and features. NVMe ¬†While supporting today’s database/data warehouse workloads it supports next-gen workloads including applications based on Hadoop also.

Availability : DSSD D5 is now available for order.

Ravello helps you to setup a virtual lab if you are struggling to setup one. It can be for your training purposes, Test/Dev environments etc… Ravello integrates with AWS and Google (GCE) and the customers can have their VMs running on either of them. This is a function enabled by their specialized hypervior – HVX.

Customers can optimize their deployment for Performance or cost. While publishing the application, customers can select this and finalize their figures.

Ravello won many hearts with their offer of 1000 CPU hours free for the VMware vExperts. And they are continuing this offer as confirmed by their tweet following the news.

Virtual Labs are¬†pretty cool and you should try this if you are looking for a lab setup.William Lam’s¬†blog post will be a great help for any beginner. This post¬†explains ‘how-to’ in easy and clear steps.

I am finding it difficult to invest more time to make the maximum out of my – vExpert – free account. But I hope I will find some workaround for this.

With FLASH, things are changing ‘in a flash’ !?

The data storage industry has gone through major changes in the past 5-7 years. And is still in the phase of changes. The user requirements has changed from “More GB’s or TB’s” to “More IOPS”. Introduction of FLASH drives been a catalist for these changes along with the other changes in hardware and software industries. FLASH as a Storage drive¬†or PCIe memory is playing an important role now a days and that gave raise to many new technologies and products.


Continue reading

All-FLASH Storage Arrays¬†:¬†Many new storage companies started with AFA products and they managed to become the customer’s first-choices for the AFA arrays. As they started with AFA, they had their hardware and software designed/optimized for a complete-flash configuration. Now we are seeing the¬†competitions between the existing players and the new comers to secure¬†their place in the market. Their (the hybrid vendors’) success will be measured on how the well the Operating Environment (in-use for hybrid) is now optimized for an AFA configuration.

With the variety of FLASH memory modules available – NVRAM, PCIe FLASH, SSDs – the AFA’s are going Hybrid AFA’s also.That shows the degree of change from HDD-based storage to Hybrid-Storage to AFA’s and then to Hybrid-AFAs.

NVMe, 3D XPOINT and more… : The increasing demand for FLASH lead to many researches and many new technologies including Intel’s¬†NVMe¬†and 3D XPoint,¬†the recent. FLASH¬†memories made their entry as¬†server-side PCIe FLASH¬†initially and now storage systems as PCIe FLASH (Along with SSD drives) . NVMe was introduced as a Standard protocol¬†for accessing PCIe FLASH. Read more about NVMe here

3D XPoint introduced a memory architecture with higher performance and low cost, which can be a mid-layer for DRAM and FLASH (can be up to 1000x faster than NAND and up to 1000x  the endurance) . 3D XPOINT combines the advantages of existing technologies like the performance of DRAM and lower cost and volatility of NAND. This new technology was announced by Intel and Micron in the mid of 2015.

A post mentioning 3D XPOINT will be incomplete without this architecture diagram. Courtesy : intel.com

A post mentioning 3D XPOINT will be incomplete without this architecture diagram. Courtesy : intel.com

With the stackable memory architecture 3D XPOINT have an improved density (more memory in less space). Data cells are read by varying the voltage being sent and this reduces the need of transistors. This is another reason for cost reduction. Faster cell switching and fast-write algorithm reduces the latency of IO in 3D XPOINT technology. Being comparatively new technology, 3D XPOINT will take few more months to have a real impact in the market.

Intel Optane technology of new Intel SSDs with high performance and high endurance is based on the 3D XPOINT technology.

SFD8 presentation from Intel had a lot about NVMe and 3D XPOINT. Looking forward to their presentation at SFD9 in March. They may have many thing new to discuss this time, 6 months is a long time.

SFD8 presentation videos from Intel are available here. More write-ups from Tech Field delegates are available here.
