Virtualization drastically changed the way we deploy applications and servers within our datacenters – eliminating racks upon racks of single purpose servers and replacing them with compute clusters and shared storage. In terms of IT, the timespan that virtualization has been mainstream has been short, but even in the small amount of time that it has been in our datacenters we have seen evolutions in the underlying infrastructure that supports virtualization. We’ve seen converged systems enter the marketplace, bundling the server clusters and storage together under one support SKU. From there we’ve went one level further with hyperconvergence, eliminating all of the complexity and troubles of having separate pieces of infrastructure for compute and storage. Hyperconvergence has certainly made a foot hold on the industry, but for the most part the target customer for these types of deployments have been aimed at small, medium and large ENTERPRISE, not business. Hyperconvergence is a perfect fit for the SMB, however up until now has been out of reach in terms of price for companies needing a small deployment for 50-100 VMs…
StarWind has been around since 2003 and are most famous for their flagship product StarWind Virtual SAN – a shared storage solution running on Windows and providing capacity to both VMware and Hyper-V clusters. StarWind have supported a 2 node, highly available storage setup for VMware with their Virtual SAN for a few years and have had success doing so. However now they have taken that one step further by providing a hyperconverged solution including the hardware, computer, storage, network, and management under one simple solution called the StarWind HyperConverged Appliance (HCA)
Before we get too much into the software driving the HCA let’s first take a step back and checkout some of the unique ways StarWind is providing hardware. The commodity servers underneath the StarWind HyperConverged Appliance (HCA) are key to how they are able to offer their powerful solution, yet keep costs at a minimum and target SMB’s and ROBOs. We have a few options when it comes to hardware and the StarWind HCA – we can buy new, refurbished, or quite simply, bring our own hardware.
You will see the phrase “best in breed” a lot within this review as that is the path that StarWind has chosen to take while putting together the pieces of their HCA. StarWind is a software company, not a hardware company so they’ve opted to chose Dell as their preferred provider for the infrastructure beneath the HCA. As we all know Dell brings tremendous solutions to their customers, providing infrastructure that can be scaled to meet the needs of the “mom and pop” shop all the way through to the large enterprise. Not to mention they have one of the biggest distributions in the world for providing hardware and servicing warranty and parts replacements.
Whether you chose to buy new or refurbished (StarWind has partnered with xByte and Arrow) there are some commonalities between the solutions. First off, customers have the option to purchase up to 5 years of 4 hour pro support on any hardware purchased (even refurbished) so you can ensure that you are covered in terms of hardware failures. Also, whether it’s new or refurbished hardware, the StarWind HCA comes in three different flavors, ranging from small to large depending on your needs.
Model S – The HCA Model S is the entry level system which is mainly designed and targeted at SMBs and ROBOs. This unit, a Dell T320 is a tower format – perfect for those remote/small offices that don’t have proper data centers or racks already installed. The Model S does not require additional network switching and can be connected directly into existing switches – while all storage traffic is routed through a directly connected 10GbE back end. The Model S starts with a 2-node starter set, and scales out to a maximum of 16 nodes.
Model L – HCA Model L takes the next step and provides a mid-level system for SMBs, providing the ability to pack more CPU, Memory, and storage into each node and moving up into a rack architecture (Dell R620). Again, the 2 node starter set utilizes existing switching and scales to a maximum of 64 nodes.
Model XL – Finally, the Model XL provides yet even bigger hardware configurations and faster CPU’s. As with the Model L this solution comes in a rack mount architecture (Del R720) and is designed for SMBs with high performance computing demands, VDI deployments, or mid-size enterprise ROBOs. The Model XL provides us with maximum storage density and allows us utilize a dedicated 10 or 40 GbE back end for storage traffic. Just like the other models the starter set comes with 2 nodes, with the Model XL having the capability to scale to 64 nodes total.
As we can see above there is a wide range of compute, memory, storage and networking configurations available with the HCA which can meet the needs of almost any SMB/ROBO deployment out there. All models are equipped with a direct connected 10GB backend to handle the storage replications and are sold on a node by node basis, or in a 2-node starter set to get you up and running quickly.
One advantage to the StarWind solution is that you aren’t locked in to specific model types once you purchase them. In fact, StarWind has published many “typical configurations” that meet the needs of various use-cases for the SMB.
Two Model L Nodes – Typical setup for an SMB looking to run a File Server, Exchange environment, SQL Server, etc.
Three Model L Nodes – Same as the previous configuration, but with an additional node added to provide more compute and storage to run additional workloads.
Three Model L Nodes + Two Model XL Nodes – Configuration for an SMB looking to run File Server, Exchange, SQL Server, etc with the addition for a 150 seat VDI deployment.
Three Model L Nodes + Two Model XL Nodes + Six Model S Nodes – This would be a typical setup for those organizations looking to deploy a central solution with support for three remote offices. Each remote office would have a 2-node Model S cluster to support local services. The 3 Model L and 2 Model XL nodes would be deployed at a central office to provide support for File Server, Exchange, SQL, VDI, etc as well as acting as a replication target for the remote locations.
Bring your own hardware
If the solutions provided by StarWind don’t quite meet your requirements, or if you simply want to leverage a past investment, customers also have the option to use their own hardware for the StarWind HCA. By purchasing just the software, services and support, a small business is able to keep costs down while getting more bang for their buck on their previous hardware investments by utilizing infrastructure they may already have in place. Obviously there are concerns in terms of warranty and support when going with this model, but the key is there is a lot of flexibility when it comes to how the customer can deploy the StarWind HCA.
Let’s face it, the underlying hardware is quickly becoming a commodity in today’s world and focus has quickly moved to the functionality of the software. StarWind recognizes this and has taken a stance to deploy their HCA in a “best of breed” type scenario. To best understand the this we can look no further than the diagram below, which outlines each piece of software included within StarWinds VMware offering…
The StarWind HCA comes at a minimum with 2 servers running vSphere 6 yet can scale to 64 nodes easily by simply dropping in more hosts. As far as management goes the vCenter Server Appliance is licensed and preconfigured within the StarWind HCA in order to allow organizations to manage their environment with a product they may already be familiar with – no need to learn new interfaces or attend respective training. It should be noted that this review is focused around VMware, but the StarWind HCA does support Microsoft Hyper-V as well.
Hyperconvergence takes our traditional storage arrays, those big metal, external, shared storage solutions and collapses them down into the local storage, which in turn performs some magic and presents these local disks back out to the cluster as shared storage. StarWind has built their company based on providing shared storage to clusters and their shared storage product, StarWind Virtual SAN is the backbone to providing availability within their HCA deployment, thus, we will spend most of our time focusing on this.
StarWind Virtual SAN is an installable product that runs on Microsoft Windows. With a two-node deployment of the StarWind Hyperconverged Appliance you will see two instances of StarWind Virtual SAN, with each VM living on its’ own node. From there, the local storage is claimed by the corresponding Virtual SAN VM, and presented back out to the ESXi hosts in terms of an iSCSI datastore. The real power of Virtual SAN however comes in the form of availability as the product comes preconfigured in a highly available model. It does this by utilizing NICs within the ESXi hosts to synchronously mirror the datastore from one Virtual SAN instance to what they call a Replication Partner, which is essentially the StarWind Virtual SAN instance on the other host. On the ESXi host end of things, the software iSCSI initiator is used and binds multiple paths to the iSCSI target together, with each path pointing to a different StarWind Virtual SAN instance. When looking at it from a physical mapping we see StarWind utilize 2 NICs on each ESXi host for their synchronization/replication traffic, as well as 1 NIC for their heartbeating/failover mechanisms.
Aside from availability StarWind Virtual SAN offers a lot more as well – too much really to go over in this post but could possible use a post of its own. In terms of my favorites check out the following list.
- Server-Side Cache – RAM and flash-based devices are utilized to provide performance in terms of write-back caching, which in turn reduces I/O latency and eliminates a lot of useless network traffic. These caches, well, they are also synchronized between hosts so we aren’t left in a situation that could result in data loss.
- Scale – StarWind can scale in multiple ways including both up and out. We can scale up by simply increasing the number of drives and spindles that we have within each node. Scaling out is achieved by adding another node complete with StarWind Virtual SAN which in turn gives us capacity, as well as CPU and Memory to our cluster.
- Deduplication and Compression – Most physical arrays are deploying this in some fashion these days and even though StarWind Virtual SAN is software-based we can still get the capacity and I/O advantages that are offered through built-in inline deduplication and compression.
- Snapshots – LUN based snapshots are provided within StarWind Virtual SAN and cold data can also be redirected to a less expensive, secondary storage tier if need be.
- Future integration with VVOLs now in tech preview.
Be it the StarWind HCA is doing a great job at providing availability for your production data locally there are still times where corruption, or user-generated events happen and a backup need be called upon to save the day. StarWind doesn’t have a backup solution of their own so in a true “best of breed” mentality they have went out and selected Veeam as their preferred partner to provide data protection within the HCA solution. If customers opt to purchase Veeam with the StarWind HCA, it means that Veeam Backup & Replication (currently v8) will come pre-installed and fully configured along with all the other software – the only thing that the customer has left to do is add some backup storage and setup the backup jobs.
Another huge benefit of going with the StarWind HCA comes in terms of support. Although the StarWind HCA contains various pieces from different vendors (StarWind, VMware, Veeam, Dell) all of the support and maintenance is processed under one SKU, leaving the customer with only one number to dial when needing some help. This eliminates all of the “he said, she said” and finger-pointing that sometimes happen when dealing with multiple vendors support on their own. All support is handled by StarWind Software, and is provided 24/7, 365 days a year.
What does it look like in the end?
When you purchase a StarWind 2 node HCA you can expect to see something similar to the following diagram
First up, 2 nodes, preinstalled with ESXi and fully configured. On top of those we have a StarWind Virtual SAN node on each host, which claims all of the local storage and presents it back to the corresponding ESXi hosts in a fully replicated, highly available manner. The key to the whole solution is that when the units are shipped to you they are completely configured and ready to go, with 4 preconfigured VMs (vCenter, StarWind Virtual SAN x2, and Veeam) – all you have to do is start deploying virtual machines and supporting your business.
As far as networking goes it will all be preconfigured for us, with the exception of the domain network (management/production) which would be specific to your business. We can see that we have dedicated links for the heartbeating mechanisms (the magic behind Virtual SANs failover mechanism as well as dedicated links to handle the storage replication – the magic behind availability.
So what do I think…
StarWind has been in the software SAN game for a long time and it’s nice to see them start to provide a complete solution including the hardware and configuration as well. Hyperconvergence is a great solution, which fits perfectly into the SMB space – however solutions today seem to be priced outside of what an SMB can afford. StarWind has placed their hyperconverged solution at a price in which the SMB can handle – and provided a complete solution, including the hardware, software, hypervisor, and data protection – all under one support umbrella. This is StarWinds first generation of their HCA so I’m excited to see where they go from here – I’ve already been told that they are previewing support for features such as VMware’s VVOLs so work is still being done. In fact, it seams to me that a lot of the features we see on traditional hardware based arrays are also being supported on StarWinds software based Virtual SAN. The StarWind HCA is a very easy solution to use – essentially it’s just vSphere and requires no configuration from the clients end. In the end my overall experience with the StarWind HCA has been a good one! StarWind HCA not only brings simplicity with their appliance, but also choice! Customers can chose to utilize new or refurbished hardware, or simply roll their own install. They can chose to include Veeam within their HCA deployment or go some other route! They can chose to scale up or scale out depending on their needs Choice and simplicity is key when it comes to providing a solution to SMB as they don’t normally have the IT resources, budget or time to spend on training and deployment. The StarWind HCA is certainly a viable option for those small businesses that fit that description, looking to deploy an easy to use, highly available hyperconverged solution that can grow and shrink as they do at a fraction of the cost of other solutions out there today.
If you would like to learn more about StarWinds HCA you can do so here – also, they offer a fully functioning trial version and also a free version of StarWind Virtual SAN – the backbone of the HCA.

And another installment of Friday Shorts – a spot for me to share some awesomeness I’ve found on the interwebs, upcoming events and info from some awesome blog sponsors, and just random thoughts around events and news that might not quite fit within the niche of this blog – basically a mashup of my brain!
First up – free passes to VMworld
VMworld is sneaking up faster than you think! Have you got your conference pass yet? If not why not help ease the pain on your company by letting VMTurbo pick up the conference pass for you? Along with ensuring performance and maximizing efficiency in your data center the folks at VMTurbo are doing their best put a full VMworld US conference pass in the hands of three people – you can sign up here and the drawings for the three passes take place on May 29th, June 19th, and July 10th! Good luck!
More freebies from Unitrends
So VMTurbo has you covered for the conference pass how’s about getting a little money to help cover the travel costs from Unitrends (trust me you will need it – the prices of hotels are crazy this year in San Fran). Just this week Unitrends released Unitrends Free – a completely free, full featured backup solution for up to 1TB of data – I reviewed it here if you missed it! Anyways, asides from putting a completely free backup product into your lab or data center Unitrends has a gig going right now where you can win a $1500 Visa Giftcard, just for downloading and registering FREE software. You have till the end of June on this one so best get signed up!
Upcoming Starwind webinar
Starwind Software, a long time mwpreston.net sponsor and creator of Starwind Virtual SAN have a webinar coming up on May 20 titled Snapshots vs Replication – chosing the right data protection strategy, presented by Chris Evans. If your interested I definitely recommend checking it out as making the choice between snapshots and replication and/or both are key in developing a fool proof data protection strategy! Also, if you haven’t checked out Starwind Virtual SAN I would take a look at it as well. I’ve used their free version in the lab numerous times for different projects!
EMC virtual VNX
Conference season is among us and with that comes a slew of releases and announcements. One that caught my attention coming out of EMCworld was the release of a community edition of the VNXe software. Shipped as an OVA you can simply load it into your environment and get the functionality and software stack of a VNXe, but without the dedicated storage hardware and controllers. I love messing around with all different types of storage and VSA’s in the lab so I’ll for sure be looking at this a little closer!
Au reviour les habitants
And last but not least, and certainly the saddest news of the week is the second round exit from the Stanley Cup playoffs for my beloved habs! Honestly the bleu, blanc, et rouge had a great season, picking up 110 points and finishing 2nd overall in the eastern conference. Their goalie, Carey Price had a career year – picking up nominations for both the Hart (League MVP) and Vezina (Best Goalie), and more than likely will take both these trophies home this summer. That said expectations around hockey in Montreal are high and a second round exit overshadows all the success that they had! Anyways we know Carey probably doesn’t care about those two trophies and is now out of the running for the only one he wanted. All that said the Habs have a great core, and they are young – so hopefully we see improvements for years to come – they will need to pick up another top 6 forward though if they want to go anywhere in the post season! At the end, they are now on the links and hopefully that means a little more time for me to work on this blog 🙂 Au revoir! Ole!
November 15th was a pretty big day for the teams over at StarWind Software. Three press releases came out from the company yesterday dealing not only with their iSCSI SAN solution but they are now a player in the backup space. First off the recently released iSCSI SAN with High Availability is now available for the low low price of FREE! There are some restrictions on the amount of data within the free edition however it’s still a great piece of technology to pull down and try! Full press release is here.
Next up is the backup announcements. A new version of their Storage Software and a Enhanced Backup for Windows Server Hyper-V is out now. Again, another press release here. Also last but certainly not least is the Backup Solution for VMware has now also been launched with full support for vSphere 5.1 – once more, press release here.
Big congrats to the teams over at StarWinds on a crazy launch day 🙂
As you’ve probably already guessed from the name of this post mwpreston dot net is finally in the books as being one year old. Honestly this is a fairly big accomplishment for me. It’s been a long ride since those first few blog posts (Hey, Who’s the new guy? and VMworld 2011 and the community that surrounds it) Before starting this blog I have tried on numerous occasions to start others, all sort of falling by the wayside and ending up with me just giving up! So what was my key to obtaining success with this one? I’m not really sure, I think just sticking with it and comitting the time to try to get at the very least one post a week out there. Finally I started to get some readers, then the sponsors came and its been a great ride since then!
So what has the first year entailed for this blog? Well, for starters I’ve had some great sponsors (Veeam, PHD Virtual, AppAssure, Starwind and BitRefinery) come on board. This definitely helps cover costs of hosting and gear that it takes to produce the content. I’m very grateful to have them on the site! Secondly this blog played a pivotal role in my reciving the vExpert designation for 2012. I can’t tell you how much that award means to me. To be recognized by the company who’s technology you have so much passion for is amazing and humbling. And lastly (but most certainly definetly not even close to least) this blog has given myself the avenue to share back any knowledge I can with the community that I love and have learned so much from! A community that has brought me from your standard sysadmin, to a VCP, to a VMworld attendee to a vExpert! Its truly awesome to be able to share, engage, and participate within this group!
And to close out this wonderful birthday I have a few tidbits of stats to share…
- There have been 91 posts over the last year along with another 48 pages covering the complete VCP5 study guide and practice tests (VCAPs coming, I promise :))
- During the first 30 days of its life this blog received 300 hits, during the last 30 days, 16000+
- Overall for the year mwpreston has received just shy of 100,000 pageviews serving just shy of 50,000 unique visitors.
- The OMG mwpreston.net VCP 5 Exam Blueprint Study Guide Dissection has recieved 3500+ downloads! WOW!
- mwpreston dot net placed 125th out of 187 on the vSphere-Land Top Virtualization blogs – also got the 13th best new blog.
- For the most part the top posts have been the VCP5 page, study guide and practice exams. Aside from those the next top 5 posts have been…
That’s really all I have for now. Although some of the numbers are low I’ve very proud of the success I’ve had thus far and very grateful for my readers and their comments they have left. Thank you all so much for reading and Ill do my best to continue to blog as much and as often as I can.
StarWind Software, a global leader in storage management and SAN software for small and midsize companies (or in the community terms – the company with the iSCSI SAN) has released a new whitepaper titled ;’Why Is 3-Way Synchronous Mirroring Better Than 2-Way?’
This white paper describes the difference between 3-and 2-way synchronous mirroring – capabilities that are both available in the StarWind iSCSI SAN & NAS solution. The document outlines the advantages of the 3-node high availability storage cluster that provides cost efficiency, increased reliability, and higher performance compared to 2-node HA. You can go and grab a copy of it here. While your there, you might as well grab yourself a copy of their FREE iSCSI SAN and try it out to see if it has a fit for you.
One of the new features coming out inside of Windows Server 2012 is the ability to create what's called a Scaled Out File Server. The Scale-Out File server is basically and active/active cluster solution in which all file servers can serve SMB client requests, so long as the scaled-out file shares are hosted on shared storage. StarWind Software for years have been providing a software solution for shared storage, eliminating the need for expensive SAN or unreliable NAS hardware. Starwind has issued a press release stating their involvement with the Scaled Out File Server and how they can basically take the directly attached storage from the nodes, and simply turn that into shared storage for your clustered environment, eliminating the need to purchase additional hardware to support the new Microsoft feature. Certainly this could be a great option for a SMB looking to provide some high availability without breaking the bank! You can check out the full press release here.
