Say VDI very fast

This one bugs me.

All the talk about Virtual Desktop Infrastructure (VDI) and how VDI is the next IN thing is beginning to look like hulla baloo to me. Every storage vendor in town is packaging their VDI messaging in the best gift wrapping paper possible, trying to win the hearts of potential customers. But I have a creeping feeling that the customers in Malaysia and even perhaps some in the region are going to be disappointed when all the fluff and huff of VDI meets reality.

I have to admit that I have no experience with VDI. I have no implementation experience, and I have no selling experience of VDI, but having gone through the years looking and observing at the centralized computing and thin client space, history could be repeating itself (again!). Many previous pre-VDI experiences have fallen flat on the face.

Remember the days of X-terminals, early versions of thin clients? Remember the names such as NCD (Network Computing Devices), Wyse Technologies (they were recently acquired by Dell), SCO Tarantella and the infamous Javastation? I don’t know about you, but that Javastation design was one ugly motherf****r.

So, it is my pleasure to remind you again and hopefully give you some nightmares too 😉

Back to VDI. Yes, the thin-client/zero-client/remote desktop/VDI concept is a great idea! I would have love VDI to be successful. It will be the implementation and the continuous user complaints that will be the bane of its problems. Ultimately, it’s the user’s experience that counts. Continue reading →

APIs that stick in Storage

By | | , , , , , ,

The competition in storage networking and data management is forever going to get fiercer. And there is always going to be the question of either having open standards APIs or proprietary APIs because storage networking and data management technologies constantly have to balance between gaining a competitive advantage with proprietary APIs  or getting greater market acceptance with open standards APIs.

The flip side, is having proprietary APIs could limit and stunt the growth of the solution but with much better integration and interoperability with complementary solutions. Open standards APIs could make the entire market a plain, vanilla one where there is little difference between technology A or B or C or X, and in the long run, could give lesser incentive for technology innovation.

I am not an API guy. I do not code or do development work on APIs, but I do like APIs (Application Programming Interface). I have my fair share of APIs which can be considered open or proprietary depending on who you talk to. My understanding is that an API might be more open if there are many ISVs, developers and industry supporters endorsing it and have a valid (and usually profit-related) agenda to make the API open.

I can share some work experience with some APIs I have either worked in the past or give my views of some present cool APIs that are related to storage networking and data management.

One of the API-related works I did was with the EMC Centera. I was working with Schlumberger to create a file-level archiving/lifecycle management solution for the GeoFrame seismic files with the EMC Centera. This was back in 2008.

EMC Centera does not present itself as a NAS box (even though I believe, IDC lumps Centera sales numbers to worldwide NAS market figures, unless I am no longer correct chronologically) but rather through ISVs and application-level integration with the EMC Centera API. Here’s a high-level look of how the EMC Centera talks to application with the API.

Note: EMC Centera can also present a NAS integration interface through NFS, CIFS, HTTP and FTP protocols, but the customer must involve (may have to purchase) the EMC Centera Universal Access software appliance. This is for applications that do not have the level of development and integration to interface with the EMC Centera API.

Can VSA help NetApp?

Almost a year ago, I had an interview with VMware Malaysia for a Senior SE position. They wanted a pre-sales guy who knows Oil & Gas and a strong technology background. I had a strong storage background, and I was involved in Oil & Gas upstream since my NetApp and EMC days.

I thought I was their guy having being led to believe (mostly by my own self-belief) to be so. I didn’t get the job but I did not find out the reason why I lost the opportunity. But I remembered well that I brashly mentioned to the Australian interviewer over the phone that VMware could become the next “storage technology” company. At that time, VMware just launched their VMware 5.0 and along with it, their vSphere Storage Appliance (VSA). This was a turning point of the virtual storage appliance space.

My friend, whose company is a VMware partner, said that the list price for the vSphere VSA was USD5,000.00 a pop. The price wasn’t too bad to the small-medium-enterprise businesses in Malaysia, minus the hardware and storage capacity cost. But what intrigued me back then was this virtual storage appliance concept was disruptive.

VMware could potentially take large JBOD farms, each for the minimum of 3 physical ESXi nodes and build a shared storage using the vSphere Storage Appliance (VSA). Who needs shared iSCSI or Fibre Channel LUNs anymore if VMware had its way?

But VMware still pretty much depended on their storage partners, especially its master, EMC and so I believe VMware held back pushing VSA for the reason of allowing its storage partner ecosystem to thrive. And for that reason, the vSphere Storage API such as VAAI and VASA were developed since vSphere 4 to enhance the deeper integration of these storage vendor’s technology into the VMware world.

But of course, long before the VMware’s VSA venture, HP LeftHand already had one on the cards. The LeftHand Virtual SAN Appliance (also VSA) was already getting rave comments from their partners and customers, impressed with how they were able to showcase HP LeftHand storage solution and technology brilliantly. Eventually, HP recognized the prowess of the LeftHand VSA and started marketing it as HP StoreVirtual VSA. I don’t hear much about the HP LeftHand (since has been renamed as P4000) VSA nowadays, seeing the HP guys in Malaysia preferring to pitch the physical storage than the virtual storage software.

NetApp, back in Q1 of 2012, also decided to go down the path of virtual storage appliance, announcing the ONTAP-v to the world here. It was initially resold through the Fujitsu partnership, but the Q1 announcement expands the ONTAP-v to a larger set of server vendors as shown below. The key component is to have a qualified RAID controller in each of the server vendors.

HUS VM is not virtual storage appliance

I was very confused with an recent HDS announcement, and it has been at the back of my mind for several weeks now.

On the last week of September 2012, HDS announced their Hitachi Unified Storage VM, aimed at small/medium enterprises (SMEs). Nothing wrong with that, except the VM part. I am not sure if it was the Computerworld author’s mistake, but he specifically mentioned VM as “virtual machine”. Check out the link here and the screenshot below:

It got me a bit riled up thinking this was some kind of virtual storage ala VMware Virtual Storage Appliance or NetApp ONTAP-V or even the early innovation of HP Lefthand Virtual SAN Appliance. Apparently not!

I did some short investigation and found Nigel Poulton’s blog which gave a fantastic dissection about the HUS VM. The VM is not virtual machine, but Virtual Midrange!

The HUS VM architecture is deep in ASICs, given HDS long history in ASICs design and manufacturing. SiliconFS, is the NAS front end, while the iSCSI and FC part are being serviced from the same HDS microcode of the higher end HDS VSP. Here’s a look at the hardware architectural diagram from Nigel’s blog:

There are plenty of bells and whistles in the HUS VM, armed with plenty of 8Gbps FC ports, SAS 6Gbps backend, SSDs, and software such as Dynamic Provisioning (thin provisioning) and Dynamic Tiering.

Yes, Yes, I have been inactive for almost 2 months. There were many things I had to do to put my business back into shape again, and hence my lack of activities in my blog.

Yes, Yes, I have a lot of catching up to do, but first I would like to report that one of the more prominent web hosting companies (many of who frequently brand themselves as “Cloud” companies) in Malaysia have been hacked.

I got the news at about 8.00am on September 28th morning and I was in Bangalore, India. Friend of mine buzzed me on Facebook Messenger, and shared with me the following:

Thursday, September 27, 2012 1:46 AM
Date: 27th Sep 2012
Time: 6.01PM GMT +0800

We have an intrusion incident that happened early this morning around 12midnight of 27th September 2012. About 50 customers’ Virtual Machines hosted on our CLOUD were deleted from the cloud server. When we spotted the abnormal behavior, we managed to stop the intruder from causing more damages to our system.

From our initial investigation, we suspect one of our employees who will leave the company at this month end logged into one of our control panels and deleted some Virtual Machines. The backup was terminated at the same time when the Virtual Machines were deleted.

At this point of time, our team is working relentlessly on restoring the affected virtual machines and customer data.

In the mean time, my COO is lodging a police report and my manager is lodging a report to MyCERT while I am writing this email.

We are truly sorry about the whole incident as it has caused a great deal of inconvenience to our customers and their end customers as well.

Please also be rest assured that our CLOUD is truly secured; this incident was not a successful hacking attempt but rather sabotage via an ordinary login.

Detailed investigation reports will be compiled and sent to our customers.

Sincerely,

Chan Kee Siak
Founder and CEO

===================================
Summary / History of issues:
===================================
27th Sep 2012,

1.00am:
- We detected several virtual machines on the cloud were throwing warning signals.
- Technical Managers were immediately informed.

01.30am:
- We found out that an intruder was attempting to delete some of the virtual machines on our CLOUD cluster.
- The intruder was using a valid login to access our CLOUD control panel.
- COO was informed, signed in to co-ordinate.
- The access of the intruder has been disabled to prevent further damage.
- We posted an announcement at: https://support.exabytes.com.my/News/2248/c...aintenance.aspx

02.00am:
- CEO was informed.
- We found out that the intruder was using the login ID and password which belonged to one of the staff members whom we had recently sent out termination notice. The last working day of this staff was end of this month.
- Around 50++ Virtual Machines / VPS were affected.
- We started to inform affected customers.

02.30am:
- Rebuild and restoration of virtual machines began.

10.00am:
- Some Virtual Machines were Restored. The rest were still pending, on going.
- For Virtual machines without extra R1Soft Backup, we have recreated blank virtual machines with Operating System.

12:30pm:
- Attempted to recover the deleted backup on the CLOUD Backup server via data recovery tool. No guarantee and no ETA yet, we were doing our very best.

5.39pm:
- 80% of virtual machines were recreated. However, some were without the latest backup of data.
- Our engineers were attempting to recover the Cloud Backup Hard Drive with the use of recovery tool. However, as the size was huge, it might take few more hours.

Damage:
- The CLOUD Accounts, Virtual Machines and CLOUD Backup of affected clients were deleted. Only client with additional R1Soft backup still has the recent backup.

=================================

Date: 27th September 2012
Time: 1:55 AM GMT+8

Maintenance Details:
We have been alert by our monitoring system that certain Cloud VM has been found to be inaccessible. Our senior admin engineers are now working to resolve the issues.

Maintenance effect:
VMs affected isolated under MY-CLOUD-02 Zone.

We regret for any inconveniences caused.

Best regards,

The beginning of the end of FCoE

Never bet against Ethernet!

I am sure many IT experts and practitioners would agree. In the past 30 years or so, Ethernet has fought and won against many so-called would be “Ethernet killers”. The one that stood out for me was ATM (Asynchronous Transfer Mode) because in my past job, I implemented NFS over ATM, running in LANE (LAN Emulation) mode in a NetApp filer setup in Sarawak Shell.

That was more than 10 years ago. And 10 years ago, ATM was hot technology. It was touted as the next generation network technology and supposed to unify the voice, data and network together. ATM also had better framing and QOS (Quality-of-Service) control and offers several modes of traffic shaping and policies. And today, ATM is reduced to a niche telecommunication protocol, and do not participate much in the LAN technology space.

That was the networking space. The storage networking space is dominated by Fibre Channel for almost 15 years. Fibre Channel is a serial technology that replaced the channel-based technology of SCSI in the enterprise. And Fibre Channel has also grown leaps and bounds, dominating the SAN (Storage Area Network) landscape with speeds up to 16Gbit/sec today.

When the networking world and storage networking world collided (I mean combined) with Fibre Channel over Ethernet (FCoE) technology some years back, one has got to give some time soon. Yup, FCoE was really hot 2 years ago, but where is it today? Is Cisco still singing about FCoE like it used to? What about the other storage vendors that used to have at least 1 FCoE slide in their product presentation?

Welcome to the world of IT hypes! FCoE benefits? Ability to carry LAN and SAN traffic with one piece of wire. 10 Gigabit-style, baby!

Run free … Symantec FileStore

By | |

It has been a rough and tough 3 weeks and I missed writing my blog. Last week, the toughest of the 3, was my CompTIA Storage+ training to Symantec SEs in Malaysia. They were a great crowd, and I loved it but I was really tired after that.

One exciting news during that week was the ouster of long time employee, and CEO of Symantec, Enrique Salem and replacing him with Steve Bennett, their Chairman. The news of that unfortunate event can be read from here and here. And almost hours after that, the calls to break up the Veritas portion of Symantec came up and putting pressure on the board of directors in Symantec to either spin-off the entity or sell it off.

To be fair, many observers, including me, believed that the marriage between Symantec and Veritas in 2005 wasn’t really what you would call a “match made in heaven”. It was more like strange bedfellows to me. And there was an internal joke (one that I could not verify) about the Veritas CEO, Gary Bloom’s promise to the Veritas board when he joined them from Oracle in 2000.

It went like this:

“Gary Bloom promised the Veritas board of directors in 2000 that he would be able to bring Veritas to a USD$5 billion dollar company in 5 years time. Nearing the end of the 5 years in 2005, Gary fulfilled his promise by merging with Symantec, instantly making Veritas a USD$5 billion dollar company.”

Note: This is just an inside joke which I heard from a Veritas friend back in 2005, and by no means put Gary Bloom in a bad light. If I did, I apologize.

But back to the present. Our class last week brought up the subject of Symantec FileStore. When it first came out in October 2009, I thought it was an interesting solution. For once, I thought there was something could “out filesystem” NetApp’s ONTAP and WAFL, because Veritas had one of the best scale-out, clustered file systems. They just haven’t figured out the front end protocols yet, where NAS and iSCSI reigned. Veritas File System (VxFS) and Veritas Cluster File System as part of Veritas Cluster Server (VCS) was mature and proven in the enterprise. Along with Veritas Volume Manager (VxVM), this was perhaps THE best file system/volume management suite around. Mind you, ZFS hasn’t reached the level of prominence yet at that time.

The Storage Compass

I am sure many people in IT get pissed with IT jargons and terminologies. More so if it is a customer, especially when he or she is not well versed with the fundamental concept behind the technology architecture.

Even after 20 years, with most of it in storage, I have a hard time switching from one vendor’s jargon to another (sometimes). But it has gotten harder for me lately, since I teach ONTAP courses for NetApp, EMC Cloud Infrastructure and doing my work with the ZFS stuff. Soon, I will take on EMC VNX, Information Storage Management (ISM), Big Data courses as well, and I also plan to do some Nexenta training too.

Who would know that an ONTAP NAS volume would be known as file system in EMC VNX for File (aka Celerra), and a data set in ZFS? Or a ONTAP aggregate is almost like a ZFS pool but with some differences or a clone might be called a replica in HDS and so on …

In fact, all the definitions above could be wrong because I am getting confused. 😉 You would be too if you have to switch from one vendor’s jargon to another. And the poor EMC pre-sales who has not been with any other vendor except for EMC all his career would have a hard time rewiring his brain if he had joined another vendor like NetApp.  Or IBM, or Dell, or Oracle or anyone for that matter.  No wonder the customers are pissed.  Continue reading →

Did Dell buy a dud?

In the past few weeks, I certainly have an axe to grind with Dell, notably their acquisition of Quest Software. I have been full of praise of how Dell was purchasing the right companies in the past and how the companies Dell acquired were important chess pieces that will propel Dell into the enterprise space. Until now …

Since its first significant acquisition into the enterprise with EqualLogic in 2008, there were PerotSystems, Kace, Scalent, Boomi, Compellent, Exanet, Ocarina Networks, Force10, SonicWall, Wyse Technologies, AppAssure, and RNA Networks. (I might have missed one or two). To me, all these were good buys, and these were solid companies with a strong future in their technology and offerings. Until Dell decides to acquire Quest Software.

At the back of my mind, why the heck is Dell buying Quest Software for? And for a ballistic USD2.4 billion! That’s hell of a lot of money to spend on a company which does not have a strong portfolio of solutions and are not exactly leaders in their respective disciplines, barring Quest’s Foglight and TOAD. A quick check into Quest’s website revealed that they are in the following disciplines:
