1) HP BladeSystem architecture allows server-to-server traffic within a blade enclosure without oversubscription, while Cisco UCS requires this traffic to travel outside the enclosure.
2) Network latency calculations show HP architecture has over 50% lower latency.
3) HP provides more flexible support for both converged and non-converged Ethernet and Fibre Channel environments.
IT Brand Pulse industry brief describing a new approach to configuring virtual networks for virtual machines...layering hypervisor-based virtual networking services on top of hardware based virtual networking services. The result is more efficient management and lower costs.
As organizations deploy converged infrastructure environments, entry costs play a significant role in hardware selection. Choosing a solution that provides easy upgrade paths when increased performance and capacity are necessary is another important factor. However, as our analysis demonstrates, it is equally important to consider the future costs associated with those upgrades. Selecting hardware based solely on initial acquisition costs can lead to substantially higher costs for future bandwidth increases.
We compare the total list pricing for each tier of the Cisco UCS solution and the IBM Flex System solution to highlight the differences in the cost of bandwidth between each environment. Not only does the Cisco UCS solution have a 22.3 percent lower initial investment cost, but the costs to increase bandwidth above the baseline configuration are significantly lower than doing so on the IBM Flex System.

Network Virtualization using Shortest Path Bridging Motty Ben Atia
SPB is a networking protocol that provides several benefits over traditional networking technologies:
1) It simplifies network design by reducing the core network to a single Ethernet link state protocol that provides virtualization services for bridging, routing, and multicasting.
2) By relying only on end-point provisioning and automatic provisioning through its link state protocol, it allows "build it once and don't touch it" functionality, greatly reducing time to deploy new services.
3) It improves network robustness through sub-second failover times and eliminating spanning tree protocols.
The document discusses how future networking is being impacted by cloud/hybrid IT, software-defined networking, and network functions virtualization. Specifically:
1) The emergence of public cloud and hybrid IT models is driving more traffic to data centers and changing expectations around network flexibility and costs.
2) Software-defined WAN (SD-WAN) solutions allow businesses more control over their networks by using overlays to connect sites over multiple networks like broadband internet and MPLS.
3) Network functions virtualization (NFV) enables network functions to be deployed as software, increasing flexibility and reducing costs compared to hardware appliances.

Impact of network quality deterioration on user’s perceived operability and l...IJCNCJournal
The remote desktop environment (Virtual Desktop Infrastructure) is attracting interest as a way to
strengthen security and support mobile access ortelework. To realize the remote desktop environments, a remote desktop protocol is required to transfer information via a network about the user’s operations made on the keyboard and mouse on a terminal to the remote server. The growing popularity of remote desktop environments makes it important to determine the factors that govern the user’s perceived operability with a remote desktop protocol. It is also necessary important to find out the conditions for a wide- area live migration of virtual machines, to use resources efficiently in the remote desktop environments.
This paper examines the impact of network quality deterioration (long network delay, high packet loss,
small downlink bandwidth) on a user’s perceived operability in remote desktop environments, assuming
RDP, PCoIP and ICA as remote desktop protocol. Next, this paper studies the impact of network quality on
the performance of a live-migration of virtual machines in remote desktop environments.
This document provides an overview of cabling LANs and WANs with three key points:
1. It describes different cabling media like UTP and the straight-through and crossover cables used to connect devices on a LAN.
2. It discusses LAN segmentation using bridges, hubs and switches to reduce collisions and improve performance. Switches allow intelligent forwarding of frames to specific segments.
3. It compares peer-to-peer and client/server network models, noting that client/server scales better and provides more centralized management and security for larger networks.

AWS is estimated to be the #3 enterprise storage vendor by revenue in 2018, with storage revenue estimated between $1.1-1.486 billion in Q4 2018. By extrapolating AWS's 52% market share of the IaaS market to the storage-as-a-service market, and estimating that 15-20% of AWS's revenue comes from storage, AWS is calculated to have overtaken traditional storage vendors by revenue. If AWS maintains 35-45% annual growth, it is projected to become the #1 storage vendor by 2020, with over $3 billion in storage revenue, cementing its position as a top storage leader through sustained large investments in R&D.

The document discusses how server and storage utilization has changed with the adoption of virtualization, noting that a survey found over half of small to medium companies were using VMware hypervisors by 2016, especially among larger companies. It also explains how vMotion traffic can either share the Ethernet network with application servers or be isolated to a dedicated FC-SAS storage network. Finally, it lists some VMware and ATTO solutions related to using direct attached storage to create a SAN.
The document discusses how small to medium businesses have swung between using direct-attached storage (DAS) and storage area networks (SANs) for their VMware environments. It provides an example of a construction firm, Torcon, that converted their DAS setup into a SAN using ATTO technology to save costs and extend the usable life of their servers and storage. The conversion took less than three hours and provided benefits like isolated storage networking and easier expansion capacity. The document advocates that SAS-based SANs provide performance and flexibility comparable to fibre channel SANs at a lower cost that is suitable for cost-conscious small to medium businesses.

Elasticity vs. State? Exploring Kafka Streams Cassandra State StoreScyllaDB
kafka-streams-cassandra-state-store' is a drop-in Kafka Streams State Store implementation that persists data to Apache Cassandra.
By moving the state to an external datastore the stateful streams app (from a deployment point of view) effectively becomes stateless. This greatly improves elasticity and allows for fluent CI/CD (rolling upgrades, security patching, pod eviction, ...).
It also can also help to reduce failure recovery and rebalancing downtimes, with demos showing sporty 100ms rebalancing downtimes for your stateful Kafka Streams application, no matter the size of the application’s state.
As a bonus accessing Cassandra State Stores via 'Interactive Queries' (e.g. exposing via REST API) is simple and efficient since there's no need for an RPC layer proxying and fanning out requests to all instances of your streams application.

An All-Around Benchmark of the DBaaS MarketScyllaDB
The entire database market is moving towards Database-as-a-Service (DBaaS), resulting in a heterogeneous DBaaS landscape shaped by database vendors, cloud providers, and DBaaS brokers. This DBaaS landscape is rapidly evolving and the DBaaS products differ in their features but also their price and performance capabilities. In consequence, selecting the optimal DBaaS provider for the customer needs becomes a challenge, especially for performance-critical applications.
To enable an on-demand comparison of the DBaaS landscape we present the benchANT DBaaS Navigator, an open DBaaS comparison platform for management and deployment features, costs, and performance. The DBaaS Navigator is an open data platform that enables the comparison of over 20 DBaaS providers for the relational and NoSQL databases.
This talk will provide a brief overview of the benchmarked categories with a focus on the technical categories such as price/performance for NoSQL DBaaS and how ScyllaDB Cloud is performing.

2. Heterogeneous Workloads
Virtualization Comes of Age
The maturation of virtualization platforms, highlighted by the
recent releases of VMware vSphere 5.1 and Windows Server 2012
Hyper-V, has sharpened the focus of data center management on
increasing virtual machine (VM) density and virtualizing Tier-1
application workloads to maximize their virtualization ROI.
The average number of VMs per
server in my environment:
This technology examines the ability of Cisco UCS and HP
BladeSystems to provide useable I/O bandwidth and I/O flexibility
that are needed to support the growth of VM density and
heterogeneous workloads.
VM Density Driving Need for Useable I/O Bandwidth
IT Brand Pulse surveys indicate that IT pros project VM density will
almost double from 13 VMs/server to 24 VMs/server within the
next 24 months—driving a need for more useable
I/O bandwidth.
Heterogeneous Workloads Driving Need for Flexibility
More VMs/server means more diversity in the applications the
server I/O system must support. This drives the need for flexibility
in how blade server I/O bandwidth and policies are provisioned to
different applications.
What I need most to increase
the density of VMs per physical
servers is more:
Converged Infrastructures Demand I/O Flexibility
The convergence of compute, storage and networking into a
shared resource pool is gaining acceptance and deployment in
enterprise data centers. By definition, this sharing of resources by
multiple applications and lines of business is also driving the need
to have a flexible, high throughput and low latency blade
enclosure I/O.
41.1%
41.1% of IT professionals surveyed said “server virtualization” was the
application most driving the adoption of 10GbE in their data center.

3. Anatomy of Blade Server Chassis I/O
Application Performance Depends on a Healthy Network
Every blade server chassis has an entire network embedded inside to carry east-west traffic between servers,
and north-south traffic to top-of-rack, end-of-row, and core switches upstream. The I/O performance of
heterogeneous applications running on virtualized blade servers can differ significantly based on:
The ability of some blade server networks to scale without over-subscription
Providing native support for multiple network protocols
Delivering network traffic with low latencies by minimizing route hops
Ethernet and Fibre Channel uplinks

Document # APP2013011 v16 August, 2013
Page 3 of 12
4. Useable I/O Bandwidth
Oversubscription Reduces Available Bandwidth
Oversubscription occurs when the I/O capacity of the adapter ports connected to a switch port exceeds the
capacity of the switch port. The oversubscription ratio is the sum of the capacity of the adapter ports divided
by the capacity of the switch port.
Oversubscription also results from the imbalance between outgoing bandwidth and incoming bandwidth
available from a blade server chassis to top-of-rack, end-of-row and core switches. Severe oversubscription
reduces useable bandwidth, increases network latency, slows user response time, and makes it difficult to
deliver deterministic application performance.
Blade server designers maximize useable bandwidth and minimize oversubscription. Not all blade server
architectures are optimized for these considerations.
Multi-Tiered Networks Increase Applications Latency
As data traverses a network fabric, each network tier in the path adds delays, negatively impacting
applications performance. As a result, designers also architect for minimal tiering to reduce these latencies.
Cisco UCS Hierarchical Network Architecture
The Cisco UCS design supports 8 blade servers per chassis and defaults to a hierarchical, multi-tiered, “northsouth” networking architecture in Cisco’s preferred End Host Mode. This mode is enabled by creating a
logical system where server-to-server traffic for hosts in the same fabric, travels outside the chassis to the
Fabric Interconnect.
This mode requires two fabric interconnects and two fabric extenders — with each extender providing up to
160Gb/s of total bandwidth for on active-active configuration. A fully loaded blade with a VIC 1240 quad-port
10GbE adapter plus a quad-port mezzanine extender requires 80Gb/s for a total of 640Gb/s with an 8 blade
enclosure—resulting in up to 4:1 oversubscription and reduced available bandwidth.
Oversubscription is exacerbated when the servers are on different fabrics, requiring server-to-server traffic to
travel north of the Fabric interconnects to the end of row aggregation switch. This architecture prevents
network loops but also prevents server-to-server traffic flow between interconnects, instead forcing it to
travel all the way to the end of row switch—resulting in the fabric interconnects become a north-south
bottleneck and up to 10:1 oversubscription, significantly limiting useable I/O bandwidth.
Oversubscription
Document # APP2013011 v16 August, 2013
The ratio of the switching bandwidth to the aggregate
bandwidth of all ingress (incoming) ports. High ratios
can result in latency and reduce scalability.

5. Applications Latency
Cisco UCS Network Architecture Latency
The scenarios described also illustrate the additional network tiers elements built into the UCS architecture
which can result in increasing total latency with a commensurate reduction in applications performance and
unpredictable applications behavior. A calculation of network latency is examined in greater detail later in
this report.

6. HP ProLiant Gen8 Blade Server
The Ultimate in Useable Bandwidth
HP ProLiant Gen8 blade servers offer the flexibility of network architectures optimized for server-to-server
“east-west” traffic or “north-south” traffic in/outbound from the blade enclosure. This is accomplished via
configuration options for the HP FlexFabric server network adapters and HP Virtual Connect FlexFabric
modules.
If the application places demands for server-to-server “east-west” traffic within the enclosure, an activestandby configuration is utilized with the upstream network switch connected to a single port on each HP
Virtual Connect FlexFabric module. However, if the application demands predominantly server-to-core
“north-south” traffic, an active-active configuration enables two uplink ports on the network switch,
increasing overall bandwidth and reducing oversubscription.
A c7000 enclosure with 16 blades, each with two 10GbE FlexFabric adapters and two mezzanine 10GbE
adapters requires 960Gb/sec total bandwidth. The enclosure’s available internal mid plane bandwidth of
7.2Tb/sec, about 7x the required bandwidth – results in zero oversubscription for east-west traffic flow.
For traditional north-south traffic, HP Virtual Connect FlexFabric modules with 16 downlink and 8 uplink ports
results in 2:1 oversubscription, similar or lower than Cisco’s, depending on configurations.
The 7.2 Tb/s useable bandwidth between device bays and interconnect bays allows server-to-server traffic to stay
within a single c7000 enclosure

7. HP ProLiant Gen8 Blade Server
Network Latency Comparison
The HP Virtual Connect FlexFabric architecture flexibly supports both single and separate fabric traffic pattern
implementations. However, configurations architected with separate fabrics address the enterprise
requirements for resiliency through redundancy.
The HP solution delivers lower latencies for both configurations, based on the calculations from
specifications provided by HP and Cisco.

8. I/O Flexibility
Support for Only One Network Wire Reduces I/O Flexibility
Based on IT Brand Pulse surveys, 40% of IT organizations are not converging with FCoE. For the 40% of IT
professionals who have been too busy to look at FCoE, or who say they have no plans to converge their LANs
and SANs, parallel Ethernet and Fibre Channel infrastructure will be deployed.
The modular design of blade servers make them inherently flexible. But not all blade server platforms are
equal when it comes to hosting multiple heterogeneous virtualized workloads and delivering I/O flexibility.
While some blade server designs accommodate Ethernet and native Fibre Channel connectivity, the Cisco
UCS design only supports Ethernet connectivity.
Wanted: Parallel Ethernet & Fibre Channel Networks
in 2013, the prevalent data center network architecture remains a parallel network architecture, including a mix of specialized NIC, iSCSI, and
Fibre Channel host adapters, as well as Ethernet and Fibre Channel switched fabrics. Cisco UCS blade servers support only Ethernet
connectivity. Adoption of FCoE technology is required to access installed Fibre Channel resources.
