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 focus on 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 utility safety throughout multi-cloud environments, and it’s accessible as SaaS and on prem flavors. There may be full function 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 function.
Microsegmentation is being adopted by many enterprises as a preventive device which relies on zero-trust precept. It helps defend purposes and knowledge by stopping lateral actions of unhealthy actors and containing the blast radius throughout energetic assault. Deploying zero belief microsegmentation is a really exhausting 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 purposes 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 (Permit checklist mannequin) then all these evolving adjustments in community requirement will get blocked until there’s a coverage lifecycle mechanism accessible. Software groups won’t ever have the ability to present the precise communication necessities as they carry on altering and therefore automated detection of insurance policies and adjustments is required.
Safe workload on prem cluster is obtainable in two kind components small (8U) and huge (39U) home equipment. The rationale Cisco has equipment based mostly on-prem resolution is for predictability and efficiency. In lots of circumstances distributors present VM (Digital Machine) based mostly home equipment with required specs, however the problem in VM home equipment is that underlying {hardware} could also be shared with different purposes and should compromise the efficiency. Additionally, troubleshooting for efficiency associated points turns into difficult, particularly for purposes with AI/ML processing of huge 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 may be predicted precisely.
The discharge 3.8 software program has optimized the home equipment efficiency and supporting 50-100% larger variety of workloads on similar {hardware}. This implies the prevailing clients with M5 home equipment now can help virtually double the variety of workloads within the present funding of their home equipment. The TCO (Whole Price of Possession) for present clients reduces with the brand new workload capability numbers. The brand new and previous numbers of supported workloads are as under.
All the present home equipment are based mostly on Cisco UCS C-220 M5 Gen 2 collection. The M5 collection server finish of sale/life announcement has been printed in Could 2023 and M5 based mostly Safe workload cluster has been introduced EOS/EOL on 17th August 2023 (hyperlink). Despite the fact that the M5 cluster may have help for one more 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 based mostly Software dependency mapping is run on this dataset to detect the insurance policies and adjustments 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 quicker 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 quicker community connectivity. Although the prevailing {hardware} configuration is kind of enough to deal with all these necessities, there are going to be new options and functionalities which will likely be added in future releases and people can also want further sources. Therefore with the brand new 3.8 launch we’re launching the help for the brand new M6 Gen 3 equipment for each 8U and 39U platform. The processing energy relies on the most recent Cisco C collection Gen3 servers with the most recent processors from Intel and newer N9k switches. The brand new Intel processors are highly effective with extra cores accessible per processor, therefore the full 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 will likely 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, we’ve made positive that the migration to M6 from M4/M5 is seamless by qualifying and documenting the entire course of step sensible 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 move knowledge will likely be backed up utilizing DBR (Knowledge Backup and Restore) performance and will likely be restored on the brand new cluster after migration. This ensures that there is no such thing as a knowledge loss in the course of the migration. The brokers may be configured to re-home routinely to new cluster and reinstallation of brokers just isn’t wanted.
As we all know in safety that the MTTD/MTTR should be as quick as potential, and I feel that M6 improve will herald quicker menace and coverage detection and response lowering MTTD/MTTR.
