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’ll talk about concerning the new M6 {hardware} platform and its advantages.
Safe Workload is among the safety options from Cisco that gives micro-segmentation and utility safety throughout multi-cloud environments, and it’s obtainable 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 as a result 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 software which relies on zero-trust precept. It helps shield purposes and information by stopping lateral actions of dangerous actors and containing the blast radius throughout energetic assault. Deploying zero belief microsegmentation is a really onerous job and operation intensive exercise. The tough 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 visitors whereas blocking relaxation all (Permit record mannequin) then all these evolving adjustments in community requirement will get blocked except there’s a coverage lifecycle mechanism obtainable. Utility groups won’t ever be capable of 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 accessible in two kind components small (8U) and huge (39U) home equipment. The explanation Cisco has equipment based mostly on-prem resolution is for predictability and efficiency. In lots of instances 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 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% larger variety of workloads on identical {hardware}. This implies the prevailing clients with M5 home equipment now can assist nearly double the variety of workloads within the present funding of their home equipment. The TCO (Complete Value of Possession) for present 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 based mostly 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 based mostly Safe workload cluster has been introduced EOS/EOL on 17th August 2023 (hyperlink). Although the M5 cluster could have assist 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 Utility 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 enormous quantity of dataset to be dealt with for coverage detection. The AI/ML instruments are at all times CPU intensive and demand excessive CPU assets 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 inside the cluster for communication between the nodes as the applying is distributed amongst the cluster nodes. All of those efficiency associated necessities of cluster drive the necessity to have extra CPU assets 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 might be added in future releases and people can also want further assets. 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 obtainable per processor, therefore the entire rely of processing GHz for cluster is elevated, offering extra horsepower for AI/ML-based ADM (Utility Dependency Mapping) processing. The general efficiency of the cluster might be boosted by the extra cores obtainable within the nodes.
We all know that any improve of {hardware} is a tough IT job. So, to simplify the improve job, we’ve got made positive that the migration to M6 from M4/M5 is seamless by qualifying and documenting the whole 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 information has been migrated accurately. All the prevailing configuration of the cluster with stream information might be backed up utilizing DBR (Information Backup and Restore) performance and might be restored on the brand new cluster after migration. This ensures that there isn’t any information loss throughout the migration. The brokers might be configured to re-home robotically 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 doable, and I feel that M6 improve will usher in sooner risk and coverage detection and response decreasing MTTD/MTTR.
