This weblog is about Cisco Safe Workload on premises platform {hardware} updates. The cluster {hardware} includes of UCS servers and Nexus switches that are required to be upgraded with the EOL cycles of UCS servers and Nexus Switches. On this weblog we are going to talk about concerning the new M6 {hardware} platform and its advantages.
Safe Workload is without doubt one of the safety options from Cisco that gives micro-segmentation and software safety throughout multi-cloud environments, and it’s accessible as SaaS and on prem flavors. There’s full characteristic parity between each the options, and we see that many shoppers have chosen On-prem cluster over SaaS choices because of their very own necessities pushed by their companies particularly in banking and finance, manufacturing verticals. Allow us to perceive Microsegmentation and safe workload {hardware} cluster position.
Microsegmentation is being adopted by many enterprises as a preventive instrument which relies on zero-trust precept. It helps defend functions and knowledge by stopping lateral actions of unhealthy actors and containing the blast radius throughout energetic assault. Deploying zero belief microsegmentation is a really onerous process and operation intensive exercise. The troublesome half is the coverage life cycle. The appliance necessities from the community carry on evolving as you improve, patch, or add new options to your functions and with out microsegmentation it goes unnoticed as a result of workloads can talk to one another freely. As a precept of zero belief whereas deploying microsegmentation you’re making a micro-perimeter round every of those workloads and whitelisting the meant site visitors whereas blocking relaxation all (Enable record mannequin) then all these evolving modifications in community requirement will get blocked except there’s a coverage lifecycle mechanism accessible. Software groups won’t ever be capable to present the precise communication necessities as they carry on altering and therefore computerized detection of insurance policies and modifications is required.
Safe workload on prem cluster is accessible in two type elements small (8U) and enormous (39U) home equipment. The rationale Cisco has equipment primarily based on-prem resolution is for predictability and efficiency. In lots of instances distributors present VM (Digital Machine) primarily based home equipment with required specs, however the problem in VM home equipment is that underlying {hardware} could also be shared with different functions and should compromise the efficiency. Additionally, troubleshooting for efficiency associated points turns into difficult, particularly for functions with AI/ML processing of enormous datasets. These home equipment include prebuilt racks with stacks of servers and nexus 9k switches that are hardened. Therefore, we all know the capability and the variety of workloads supported and different efficiency parameters might be predicted precisely.
The discharge 3.8 software program has optimized the home equipment efficiency and supporting 50-100% better variety of workloads on similar {hardware}. This implies the prevailing clients with M5 home equipment now can assist nearly double the variety of workloads within the current funding of their home equipment. The TCO (Complete Value of Possession) for current clients reduces with the brand new workload capability numbers. The brand new and outdated numbers of supported workloads are as under.
All the present home equipment are primarily based on Cisco UCS C-220 M5 Gen 2 collection. The M5 collection server finish of sale/life announcement has been revealed in Might 2023 and M5 primarily based Safe workload cluster has been introduced EOS/EOL on 17th August 2023 (hyperlink). Though the M5 cluster could have assist for an additional few years, there are particular advantages of upgrading the cluster to M6.
Allow us to perceive how the Micro-segmentation insurance policies are detected and enforced in CSW (Cisco Safe Workload). The community telemetry is collected from all agent-based and agentless workloads in CSW. The AI/ML primarily based Software dependency mapping is run on this dataset to detect the insurance policies and modifications to insurance policies. The insurance policies per workload are calculated after which pushed to workloads for enforcement leveraging the native OS firewalling capabilities. This can be a large quantity of dataset to be dealt with for coverage detection. The AI/ML instruments are at all times CPU intensive and demand excessive CPU sources for sooner processing. The bigger the dataset will take longer processing time and require extra CPU horsepower within the cluster to get extra granular insurance policies. It additionally wants a quick lane community throughout the cluster for communication between the nodes as the appliance is distributed amongst the cluster nodes. All of those efficiency associated necessities of cluster drive the necessity to have extra CPU sources and sooner community connectivity. Although the prevailing {hardware} configuration is kind of ample to deal with all these necessities, there are going to be new options and functionalities which can be added in future releases and people may want extra sources. Therefore with the brand new 3.8 launch we’re launching the assist for the brand new M6 Gen 3 equipment for each 8U and 39U platform. The processing energy relies on the newest Cisco C collection Gen3 servers with the newest processors from Intel and newer N9k switches. The brand new Intel processors are highly effective with extra cores accessible per processor, therefore the entire depend of processing GHz for cluster is elevated, offering extra horsepower for AI/ML-based ADM (Software Dependency Mapping) processing. The general efficiency of the cluster can be boosted by the extra cores accessible within the nodes.
We all know that any improve of {hardware} is a troublesome IT process. So, to simplify the improve process, now we have made positive that the migration to M6 from M4/M5 is seamless by qualifying and documenting the entire course of step clever within the migration information. The doc additionally mentions the checks to be carried out earlier than and after migration to verify that every one knowledge has been migrated appropriately. All the prevailing configuration of the cluster with circulation knowledge can be backed up utilizing DBR (Information Backup and Restore) performance and can be restored on the brand new cluster after migration. This ensures that there isn’t any knowledge loss throughout the migration. The brokers might be configured to re-home mechanically to new cluster and reinstallation of brokers is just not wanted.
As we all know in safety that the MTTD/MTTR have to be as quick as attainable, and I feel that M6 improve will herald sooner menace and coverage detection and response lowering MTTD/MTTR.

I loved even more than you will get done right here. The overall look is nice, and the writing is stylish, but there’s something off about the way you write that makes me think that you should be careful what you say next. I will definitely be back again and again if you protect this hike.
