Zerto facilitates IT resiliency with a single VM replication platform

Jon Klaus heard from Zerto at Storage Field Day in Boston earlier this year. In this post, he digs deep into their block level, continuous hypervisor-based VM replication. Their approach allows you to rewind your VM to a specific point in time and recover the exact state. For Jon, this removes many of the problems of VM replication he’s come across in other solutions. It doesn’t use snapshots, and uses a single IO Filter that’s easily configured. Overall he’s interesting in testing it out and learning more.


NVMe and NVMe-oF 101 with SNIA: queues everywhere!

Jon Klaus gives the rundown on NVMe and NVME-oF as presented by Dr. J Metz of SNIA at Storage Field Day in June. He details the differences between NVMe and NVMe-oF and also explains why you should even care about NVMe at all. Jon also compliments SNIA’s unbiased and informative presentation.


CloudIQ is looking out for your storage system’s health

Jon Klaus writes about Dell EMC’s CloudIQ presented at Storage Field Day 16. CloudIQ’s purpose is to keep track of your storage system performance, health, capacity and notify you in case of any anomalies. Jon was impressed by CloudIQ’s functionality, but also by it being free to use for those with a Dell EMC Unity storage system and having a responsive and active development team.


I’m shipping up to Boston for Storage Field Day 16

It’s almost Storage Field Day time for Jon Klaus. He’s shipping out to Boston and will be hearing from seven storage companies over two days this week. Make sure to follow along with Jon on the live stream during the event.


VMware Virtual Cloud Network: Networking Glue for Hybrid Clouds – Gestalt IT

In this post, Jon Klaus looks at how VMware’s newly announced Virtual Cloud Network can help overcome many of the challenges of managing a hybrid cloud deployment. He particularly focuses on VMware’s NSX SD-WAN by Velocloud as the backbone that can connect remote sites while maintaining security.


Why move to one cloud, if you can move to a multi cloud?

Jon Klaus likes the cloud, but is hesitent to depend on a single provider. He looks at how Scality’s Zenko Multi Cloud Controller allows you to easily replicate storage across multiple clouds, public and private. This often increases resiliency and cost savings at the same time.


XtremIO X2: easier scaling, fewer cables and metadata aware replication

After seeing Dell EMC’s presentation at Storage Field Day last year, Jon Klaus shares his thoughts on their XtremIO X2 storage array. Jon sees several interesting features compared to its predecessor. Among other features, Jon liked the improved flexibility when scaling storage, including offering XtremIO X2 Bricks with only partially populated disks. This makes it easier for new customers to adopt. XtremIO X2 also offers improved 5:1 data reduction, which can be achieved without a performance penalty due to its “inline everything” architecture.


VMAX All Flash: Enterprise reliability and SRDF at <1ms latency

Jon Klaus gives an overview of Dell EMC’s all flash VMAX storage array, which he saw at Storage Field Day earlier this year. This brings sub 1ms latency and high IOPS to the already reliable line.


Back to SFO for Storage Field Day 14! – FastStorage

Storage Field Day is coming up next month, and we’re happy to have the inimitable Jon Klaus returning! Returning for his seventh Storage Field Day, expect plenty of probing questions, quality analysis and stroopwafels from Jon as he sees presentations from Dell EMC, E8 Storage, and Scality.


Excelero NVMesh: lightning fast software-defined storage using commodity servers & NVMe drives

Jon Klaus came away from March’s Storage Field Day impressed with Excelero. The company came out of stealth at the event with their software defined block scale-out storage, NVMesh. This uses commodity servers and NVMe drives to deliver impressive performance. Jon gives a review of their overall architecture, their value proposition, and general impressions from their presentation.


Moving to and between clouds made simple with Elastifile Cloud File System – FastStorage

Moving data to the cloud and moving between clouds are some of the primary challenges facing organizations today. Often cloud provider lock-in is a very real concern. From what Jon Klaus saw from Elastifile, their Elastifile Cloud File System is the secret to make both easier. ECFS is designed for web scale clients and users, and can be extended into the public cloud. Designed with true distribution in mind, the file system should allow you to easy and reliably move data between on-premises and the public clouds.


SNIA: Avoiding tail latency by failing IO operations on purpose

At Storage Field Day last month, Jon Klaus saw a presentation from SNIA, where they talked about tail latency. These are tiny spikes in latency, 2-10x longer than higher. These can have big impacts, effecting up to 2% of all IO, which is magnified when seen at a hyperscale level. Smaller organizations might simply over provision to lower overall latency so that these spikes still fall within acceptable ranges, but at scale this approach isn’t practical. SNIA presented several ways to overcome tail latency, and Jon shares his thoughts on what he saw.


Intel SPDK and NVMe-oF will accelerate NVMe adoption rates

Intel’s presentation from Storage Field Day this month certainly made an impression on the delegates. Jon Klaus wrote up his thoughts. He goes into particular details over SPDK and NVMe over Fabrics, both of which he thinks will have genuine business impacts for overall NVMe adoption. For Jon, this is an example of Intel pushing software to truly catch up to recent advances in hardware.


Storage Field Day 12: storage drop bears reunited!

Storage Field Day is coming up in March, and we’re excited to have Jon Klaus returning! He wrote up a great preview of some of the companies he’s excited to see. Jon found the presenting companies to be a good mix of returning ones he’s interesting in catching up with, and new ones that will be presenting new products and solutions. It should be a great event, so make sure to check out our comprehensive video coverage, both live and after SFD!


Building a hybrid cloud with Avere

Jon Klaus takes a look at what Avere is offering with their hybrid cloud solution. He has a long history with the company, going back to when they were focused on NAS optimization via a caching layer between storage and compute resources. Avere then moved into object storage translation, and is now entering into making cloud storage gateways. He gives some thoughts about what applications their gateway would benefit, weights in on caching vs tiering, and where he thinks these kind of products fit into IT. He doesn’t see the cloud ever killing the tangible benefits of on-prem, but hybrid solutions could certainly benefit both.


Hardware has set the pace for latency, time for software to catch up

Jon Klaus thinks software needs to catch up to SSDs for reducing application latency. Initially, SSDs were limited by storage processors and buses build with spinning disks in mind. This has largely been remedied, so where’s the next big performance bottleneck? Latency.

Jon looks at how Intel’s Storage Performance Development Kit, presented at Storage Field Day in October, effects latency by replacing the traditional Linux kernel in storage controllers.
