Scenario: A Citrix Administrator maintains a Citrix Virtual Apps and Desktops Site with local storage that contains several logical disk space locations. The administrator would like to reduce the total number of writes on the storage.
What can the administrator implement with minimal administrative effort to address these needs?
To reduce the total number of writes on storage with minimal administrative effort, the administrator can implement Machine Creation Services (MCS) input/output optimization. This feature utilizes local caching to reduce the write operations on the storage, which effectively lowers the overall IOPS. Implementing MCS IO optimization is simpler and requires less administrative overhead than provisioning services (PVS) or setting up a Storage Area Network (SAN). Personal vDisk is not relevant here as it is used for providing user customization and data persistence, not reducing IOPS.
answer should be B. the key part of question is "What can the administrator implement with minimal administrative effort to address these needs?" PVS would work but the setup and implementation would not be minimal'. https://www.citrix.com/blogs/2016/08/03/introducing-mcs-storage-optimisation/
I think it's B because Admin wants to reduce write on storage, then you should use MCSIO
I go with B according to a statement of "minimal effort"
it's B - the key is the minimun effort
MCSio 100%. (answer B) I've just installed this at a customer of mine.
Answer should be B https://www.citrix.com/blogs/2016/08/03/introducing-mcs-storage-optimisation/
also not that this is a local storage situation. that is called out in this article: https://www.citrix.com/blogs/2016/08/03/introducing-mcs-storage-optimisation/ "With reduced I/O load from the memory caching mechanism, you can use local storage for temporary data, which can be a more cost effective option than using shared network attached storage."
answer should be A. the question say "The administrator would like to reduce the total number of writes on the storage." he talks about a single storage the MCS I/O optimization use at least 2 differents storage repository (Provides the ability to place differencing disks on separate local storage)
Do not think, that ctx pvs implementation is a "minimal effort"), so B
True, but the question states minimal ADMINISTRATIVE effort - not implementation effort. Once implemented, PVS does not require much effort.
B is correct
It could probably be B. https://Machine Creation Services input/output optimizationdocs.citrix.com/en-us/tech-zone/design/design-decisions/image-management.html
Advantages over using traditional MCS provisioning By using the temporary memory cache, you can significantly reduce your I/O write load on storage. You are trading RAM for storage I/O, which means you can scale up the hosted machines on your shared storage or downsize its requirements.
I mean B
B because they want to reduce the storage IOPS
It's definitely B. https://www.citrix.com/blogs/2017/03/29/mcs-storage-io-optimization-on-resource-constrained-systems/
A is right. PVS with Cache in RAM with Disk Overflow greatly reduces IOPS
B is right. Minimal administrative effort so it can't be PVS
Do not think, that ctx pvs implementation is a "minimal effort"), so B
I think is A, PVS work on RAM, MCS work on storage space
