HP C7000 iLo

What happened? Why doesn’t my iLo have an IP Address? The blade inserted has the correct profile but the iLo cannot obtain an IP address. I cannot start a remote session to the iLo….

What? What about configuration of the iLo IP Address?

HP iLo uses DHCP to obtain an IP address.

The Onboard Administrator configures this parameter.  The iLos have DHCP enabled and OA distributes addresses. Feature is called Enclosure Bay IP Addressing or EBIPA.

I was scratching my head, as it has been a while since I had to configure a new blade with the iLo.

I forget to run the full configuration for the iLo in the Onboard Administrator.

Verify the blade is functional powered on and recognized in the and the chassis isn’t throwing any errors.

Messages_Image_227066963_

Go into the OA.

Locate the Menu “First Time Setup Wizard >>> EBIPA section”

  1. Make sure the enable box is checked for the new blade
  2. Notice how the blade has not obtained an IP address yet, pending set of feature and reboot

C461BF12-14CA-4D11-87F7-F2FAAE29B20E

Once the blade has rebooted or ILo has rebooted it will have an IP address and you will be able to remotely console into the blade.

Remember to patch the latest firmware for the blade. Download the full ISO image of the SPP from HP’s site and boot from that ISO.

vmworld 2015 Highlights Day 3 VSAN 6.1

Well it is almost the end of vmworld2015. I have been incredibly busy attending so many sessions it is numbing both for the mind and my feet! The content this year has a different perspective for me. In years past it has been on the tip of everyone’s tongue a new release of x, y or z but this year it is more than that. For me it is Day 3 as I have been at vmworld 2015 since Sunday.

VSAN 6.1

This is the third major release for this product. VSAN has isn’t the new kid on the block. It is shown its ability to deliver Enterprise Class performance with the flexibility of the Software Defined Data Center. It is delivery flexibility and ease of operations as a foundation of SDS. Performance is just one of it’s attributes. The beta for a long awaited feature is announced. DEDUPLICATION

VSAN DE-DUPE BETA ”  SIGNUP FOR IT!!!

“VSAN 6.next beta – A glimpse of the future”

VSAN stretched clusters.

If you have a chance watch the session delivered by Rawlinson Rivera @Punchingclouds and Duncan Epping @duncanYB. It is a deep dive of the design of using VSAN as a stretched cluster option. Key points to remember are L2 L3 requirements and the newest feature the Witness VM. While VSAN requires L2 Multicast; the witness vm only requires L3 communication. The impact is a stretched cluster Site A and Site B while a lower latency site can host your witness VM with L3 requirements. As the Fault Domains are dependent on the use of a Witness VM and this re-design of the witness lends itself to use for VSAN as A ROBO solution.

Look for it STO5333 “Building a Stretched Cluster with Virtual SAN”

The impact of VSAN on design and deployment of a stretched / Metro cluster combined with the versatility and flexibility of vsphere 6 (Think PSC HA Think the flexibility of vmotion across VDS, VSS and different Datacenters!)

SC-VSAN

VSAN ROBO.

What is it? In nutshell VSAN can now be deployed at remote sites (Remote Office Branch Office) with only 2 nodes! Technically the third node is a witness vm.

robo

I am very excited to leverage this ROBO configuration for many customers. There is a lot of flexibility in how to implement this design. It decrease the complexity and cost of shared storage, but that is the crux of VSAN of vmware’s SDS.

Once last note about VSAN 6.1

I have had many conversations with customers and as well as the vmware VSAN team about the requirements and benefits of such architecture. This focus of this conversation was address directly in the session STO5336 “VMware Virtual SAN – Architecture Deep Dive” delivered by Rawlinson Rivera @Punchingclouds and Christos Karamanolis

Note the Hybrid Design vs the AFA VSAN are NOT the same. It that flame bait? No.

I will try to summarize it here. Both are hyper-converged SDS solutions employing the benefits of clustered storage and SSD. Both have simplified operations and lower TCO. Both deliver fantastic consistent predictable performance.

Cache is where it is at. Read Write

SSD is leverage in both the hybrid model and the AFA model but the key is the are leverage DIFFERENTLY.

70/30 Read Write for Hybrid moreover… this is the crux. The algorithm used to deliver performance for a AFA is different than the Hybrid approach.

  1.  LRU vs ARC.   That is why you cannot. I repeat CANNOT bolt on All SSD in a licensed Hybrid VSAN design and get the same performance of a  AFA solution. I have tried to explain this to a customer but one persons results skew their reasoning.  I would tend believe results that you and review that are from countless man-hours of R&D vetted against multiple manufacturers / vendors and various RA bench marks
  2.  Read Write characteristics of SSD / HDD   Not all SSD are created equal. SSD and HDD are different. vmware knows this. Hardware manufactures know this. Storage engineers know this. But Consumers sometimes know this. You have the flexibility of choosing your own hardware to fulfill your requirements for VSAN ref: vmware compatibility guide

“A candle that burns twice as bright burns half as long” 

VSAN 6.1 AFA design understands this at a much deeper level. It is designed and tested for not only performance but for longevity. VSAN 6.1 helps you sort out which SSD is appropriate.  HDD aka spinning magnetic disks can handle long term data and dense capacity at a price: IOPS. Conversely SSD can handle 10x increase in IOPS but at the cost of density and longevity.

Pick carefully your components. To borrow from the culinary world. The best ingredients make for the best food. You will consume something awesome if you cook something awesome. “You can’t make chicken salad out of chicken sh*t” lol

Reference Duncan’s explanation of the VSAN Ready Nodes http://www.yellow-bricks.com/2015/08/25/virtual-san-ready-nodes-taking-charge/

Well there is more to VSAN 6.1 and vmworld2015… more when I can find some time to share. Thanks for reading.

EMC, vmware, VSAN

Is your IT infrastructure an Oil Tanker?

I had the opportunity to attend an Avnet/EMC/VMware/Brocade sponsored for channel partners EVO-RAIL VSPEX Blue BootCamp.

In a nutshell it was all you can drink information from a firehose— about EVO-RAIL specifically the EMC VSPEX BLUE.

EVO RAIL is a new beast of an animal. It is a different breed. No, not in and single dimension you measure. The combination of technology presented is a synergy. Definition: Synergy is the creation of a whole that is greater than the simple sum of its parts.

Yes; you can get the the form factor for compute separately. You can also do the same for VSAN and ESXi vSphere 5.5 and networking. but you cannot get what the entire VSPEX BLUE offering of EVO RAIL provides TOGETHER.

I get ahead of myself.

You have to have perspective to understand where we are today. To me that means if you don’t know where you come from you  cannot know where are you today and where you will be tomorrow. It is all relative.

EVO RAIL is a clustered system. It is a Datacenter in a 2U form factor. Not just compute but a modern hyper converged solution.

DD709A0B-0F27-43AD-ABB2-F2D3D75C2601

Sure. Another IT buzzword. Is it just talk? I would say no.

Everyone is talking about it but only a few are “doing it”… more often than not the IT industry is a buzz with the new technology of the day.
In this case it is Hyper-converged.
To put it simply storage is local to compute. What a minute how is that different than 15 years ago when Client-Server model was the norm and storage was already local to the compute. Compute meaning the processing of the server CPU. Well lots has changed.
How is it better. A snapshot of what is the current available technology:
  • Compute is way, way faster and more dense.
  • Networks are 10 gigabit vs Fast Ethernet 100 Base-T or FDDI Optical rings are no longer the only viable choice.
  • Storage is IOPs crazy.
  • And add to that the agility of VMware Virtualization!
So look at the speed of compute, network and storage. Technology will continue to get faster and better (lower cost for the return on investment).
But what really hasn’t changed much is the complexity of the solution. There are many moving parts but how do you delivery your solution today to support legacy applications and have the agility to respond to changing business objectives.
The old phrase “turning an oil tanker on a dime”. Is IT today an Oil tanker? Does your private cloud have the agility your business requires? How will the current toolset respond? How will your staff? Oh what was that “IT staffing has been reduced and that is a trend that hasn’t gone away”
IT organizations are forced to do more with little… queue in viable alternatives…
Do you outsource.. the simplest short term gain, but not always the best long term investment.
I view EVO rail as a datacenter in a box. EVO-RAIL VPSEX Blue is Not the Cluster in a box solution but much much more.
This reminds me of the forerunning of MCSC cluster in a box. Like I said.. perspective. Where has the IT industry been before relative to where it is today. I recall back in the day when cluster in a box was a viable (and the best solution at the time) era 2000. That was only a high-availablity MSCS cluster with one node active at a time. 
1BB7AEF5-74F9-46FE-8971-6808D6593D0A
Yes, I deployed and supported a few of these solutions. It was cutting edge back then.
Adjusted for inflation:
$1000.00 USD in 2000 is $1395.20
so the CL1850 was $27,864.00 (2000 $)
or $38,569 in 2015 $.
But what did you get for your IT dollar?
Each “node” in the CL1850
RAM:
  • 1 GB RAM (128-MB 100-MHz registered ECC SDRAM memory)
Compute:
  • 2 Pentium III processors @550MHz
Network
  • 3 NICS (one dedicate for internode communication) 100 BaseT
Storage:
  • 2 RAID controllers
Shared Storage System:
  • 218.4 GB (6 x 36.4-GB 1′′ Ultra3 10,000 drives)
Form Factor 10U
Fast forward to 2015….What does EVO-RAIL VSPEX BLUE PROVIDE:
Each EMC VSPEX BLUE appliance includes:

  • EMC RecoverPoint for Virtual Machines for continuous data protection of VMs. Includes licenses for 15 VMs.

The question still remains. Is your IT infrastructure an Oil Tanker? OR Can you turn on a dime??

How does your IT respond the the ever changing business demands?

Is EVO RAIL for everyone? There are a lot of use cases that EVO RAIL VSPEX BLUE will work perfect for. But,  No it isn’t for everyone.  BUT what it does is usher in a new consumption of IT that is different manner. You will not have to be provision your datacenter in the same piece meal function. You can commoditize that to a pre-validated solution that is supported by a single vendor.

EMCWorld 2015 – Redefine Next … two big items to consider

emcworld

#EMCWorld

One “little” event, but this one event is in truth packed with so much activity;  you can actually feel the energy in the air.  For those who don’t know what it is about: EMC World is about: cloud computing, virtualization, Big Data storage and analytics, and IT security and protection. Each individual item alone is enough for a 4 day conference but all together under one roof. It is a lot to take in.

There is a wide audience in attendance: Vendors, Customers, Partners. So basically a little (or a lot) of something for everyone. There are multiple tracks in each topic: beginner, Intermediate and advanced. And there are different focus areas to learn about.

EMC isn’t just about storage, sure it is at its core DNA, but there is so much more to EMC than storage. If you don’t think so .. look at this:

EMC {code}

http://emccode.github.io

There are currently 33 Public Repos in development, not counting any forks.

Storage isn’t just about LUNS, RAID Groups and IOPS. No sir/ madam. DevOps is alive and well and pushing the envelop, really maximizing the technology under the hood. Making things happen you never thought possible, but more importantly redefining Next.. the next use case, the next different way to do things.

And if you are ready.. look at this current offering that well, is more mature than you might think. Don’t assume All Flash Arrays are equal. Today lots of different vendors are offering a flash array of some kind, hybrird or 100% All Flash array options.

I had a conversation recently and told my colleague I am storage agnostic, as I have worked with just about every storage vendor out there. BUT that doesn’t every storage is for everyone. You can’t force one-size fit all for storage.

There are requirements and understanding those requirements, well that is my job.

Enter…

xtremIO

xtremIO

Today I had the opportunity to meet some very incredible individuals. It may be over-used by “passionate” is what this guy is about. The details shared, I cannot discuss publicly at this time, but WOW. xtremIO 4.0 release isn’t a maintenance release it is HUGE.. to paraphrase “4.0 release is a big deal, if not as big a deal as the 1.0 release.”

Read more here:

http://www.xtremio.com

https://itzikr.wordpress.com/2015/04/10/emc-world-2015-the-xtremio-sessions/

Here is one thing to really dig deep into:

Think about how you do business today. What do you have in production? What is working? What could work better?

How could it work better?

Do you expect your Application development team to turn on a dime to adopt something new and shiny?

Agility may be a buzz word, but the cost to re-tool is a big deal. I mean, cap-ex is only one dimension. OpEX and adoption rate is not a small deal. If you have invested effort, evaluate how to make your TCO maximize the ROI. Buzz words or reality? You can’t expect to drop everything and jump to the latest and greatest just “because”. Nope. That is irresponsible. The luxury of a greenfield deployment isn’t something everyone has at their disposal.

xtremIO-ecosystem

Hint: dig deeper into “Snapshots” find about how to really leverage this for your organization.

More thoughts to consider later. Sure there are fun and games, but EMCWorld is a lot of game changing information to absorb. The theme this year is “Redefine Next” what is your next step? what is your next technology investment? Who will be on your side to put your organization in pro-active quadrant? How will you empower your team/company/self for the next 90, 180 days? How about the next fiscal year?

more later.

part 2/2 Troubleshooting VSAN errors. VSAN misconfiguration??

VSAN cluster isn’t 100% there is some problems with see all the storage. 
Symptoms:
1. Cannot write to the VSAN Datastore
2. Correct amount of capacity isn’t present
How to resolve with ESXCLI
Log into each host via ssh. You do remember the root password right?? This example is a three node VSAN cluster.
