Because you need 27 Hosts to fulfill the RAM requirements, this is the amount of hosts which = N.
For N + 1 you need to add 1 host: 28 Hosts. But the exercise states that N + 1 has to be maintained at all times, which mean N +1 has to be maintained even in Maintenance! A host in maintenance does not participate in failover capacity so you have to add 1 more host = 29 HOSTS!
Note: Suppose one of your calculations = a number higher than the maximum number of hosts per Cluster,for example 70. Each cluster would have 35 Hosts as N. Each cluster would need 37 Hosts to comply with the requirements to have N +1 redundancy at all times. Changing a host to a different cluster might not be something you want to do, it takes a lot of time and in some cases is not that easily done.
HOLD ON! Where does the 80% all of a sudden come from? Why wasn’t it mentioned in the question that 20% of the resources should be free for overhead? How can we know this if you do not mention this and why is this 20% and not 18% or 21% or any other value?
Each ESXi server needs resources to run ESXi and execute other tasks such as DRS and vMotion. If you use 100% of the resources to run VM’s, none of the other tasks which should be performed by ESXi will be able to run, ESXi will stop working and your host and all VM’s will crash. So always assume that an ESXi hosts needs resources to run itself and its tasks (unless the question specifies otherwise).
So why is this 20%? Open any decent vSphere design book and you will notice, almost everyone is using 20% for ESXi. Could this be 12%, 16%, 18% or 22%? Sure, different environments have different tollerances in overhead. But for the sake of this excersize, I am using 20%, just like my instructor in the Design Workshop (5.5) recommended to use and just like most Design books use as a default value.

Total resources needed for 1000 VMs:
2 (cores)* 2(GHz) * 1000 (VM) = 4000 GHz
1000 (VM) * 4 (GB) = 4000 GB of RAM
Available resources per hosts for VM’s = 80% of available physical resources!

You are an architect for a mid-sized company. The company has 500 virtual servers running on vSphere 5.5 and has still some 200 Physical servers which still need to be virtualized.
Of the 500 Virtual Servers 300 use on average 2Ghz CPU, 2.2 GB of RAM with an average Disk usage of 60 GB. 150 servers use on average 1.2Ghz CPU, 3 GB of RAM with an average Disk usage of 70 GB.
The Business has decided that all servers should be virtualized within this business year and the whole infrastructure has to be migrated to vSphere 6 within the next business year. The business requires that all servers will be high available and the Tier 1 servers must have an uptime of 99.95%. To be able to accomplish this, they have expressed their explicit wish to the CIO and CTO to setup a DR solution also within the next year.
The CIO and CTO think that this project is do-able but will face many difficulties which they might overcome. The DR site will have to be created and to avoid that an event such as a hurricane can destroy both datacenters at the same time they feel that the datacenters should have a minimum distance of 300 miles between them. Because the CIO has good relationships with Fiber-NU, the price for the site to site connection will be 75% of the price the competition can offer and the business has agreed that Fiber-NU will be the selected carrier.
Because there is no DR site yet, they don’t know the required bandwidth but the SME thinks that the replication for each server will not use more than 1 MB per minute. This equals 0.067 gigabits per second for all VM’s. On top of this the storage replication will take up an estimated 0.2gigabits per second. Both datacenters have to be connected through east and west of both datacenters, so 2 links will be purchased from Fiber-NU. The CTO has addressed a concern by using 1 carrier only, but because of the pricing, Fiber-NU has been selected for both East and West connection of both datacenters. Fiber-Nu is willing to deliver 2 one Gigabit connections connecting both datacenters.
Jake the CTO stresses that having only a backup solution is not enough and a DR solution has to be implemented. Because the virtualized environment already runs on vSphere 5.5 he says that SRM has to be used. He says for optimal replication the latency should be less than 10 ms. And RTO of 30 minutes will be applied for all Tier 1 servers. However database servers all SQL 2012R2 have a WRT of less than 1 minute, as such it has been decided that Microsoft failover clustering will be used for all database servers.
Jenny the FCO says that there is a budget of 2M to buy the hardware for this project and asks if this will be sufficient. Jake says 2M will be enough if they stick to the current vendors and current hardware in the existing datacenter. EMC will remain the storage partner and has agreed to buy back the current VNXs at a good price if they can sell new VNXs for both datacenters. The business is still considering this offer. As storage replication EMC’s Recover Point has already has been purchased a month ago because the pricing was excellent due to an action from the vendor. Cisco contracts are up for renewal but those contracts will be signed next week as the budget for the existing hardware renewal had already been approved. The new Cisco switches and routers for the DR datacenter still have to be purchased but these will be bought using the 2 M budget for the availability project.
The CTO raises a concern that most of the admin staff probably does not have the skills to manage a vSphere 6 environment and DR solution. It is agreed by all parties that training for the admin staff will be mandatory.

You have been working for a couple of years for Atlantic Pharmaceuticals. Atlantic Pharmaceuticals has been using NFS since the stone ages and wishes to keep doing so. Their datastores are rather big each coming in at about 12 TB per datastore. The average datastore size is expected to decrease with 10% this year but the current datastore size has to remain. For this year the CIO expressed his wish to migrate to vSphere 6.x and he wants the team to look into either an upgrade of the current NFS datastores to NFS 4.1 or a replacement. The budget has been approved as being unlimited and as such a new DR datacenter will be created a less than block way. A latency of less than 5ms has been guaranteed by the carrier.
Please select the storage protocol you would advise the CIO to use.

Atlantic Pharmaceuticals has decided it wants to migrate to VSAN 6.x. The CIO has expressed his wish to use 20 new HP blade servers which had been ordered before the project to move the infrastructure to VSAN 6.x had been signed off on. Mike the IT engineer notices that each blade has 2 free Disk slots as the Blades are booted from USB attached SD cards, so currently each Node can have a maximum of ‘3 disks’ while using remote SAN storage and NFS storage. All Blades have 64 GB of RAM. The HP enclosure and HP Blades come with dual 10 Gbit network and each blade has a 16 Gbit connection to the FC storage. Also the current servers make use of NFS 3 as datastores for VDI solution based on VMware View 5.3. The CIO has expressed his wish to keep the VDI datastores on NFS 3 but to move all other datastores to NFS 4.1.
You are a consultant hired to implement the solution and immediately you see that this is not possible.
Please select the answers why this is not possible.
(KB)
Correct
Well Done!
VSAN6.x needs at least 3 disks. Either Hybrid mode where 1 SSD would be considered for caching and at least 2 physical disks for storage.
Or full SSD where 1 SSD would be considered for caching and at least 2 SSD’s for storage. However at the moment each blade has only 1 disk!
You can have different versions on NFS in use as long as you do not use different NFS versions to access the same datastore from other hosts.
