many professional end user documents (white papers; lab manuals; step-by-step
how-to's; guides; Visios; operations documents; etc),
beginning with my work at Sun Microsystems (for their education division), and
subsequently after that for EMC, NASDAQ, Veritas, etc.; as well as
write for their (and my) end clients too. Partial/Unfinished versions of
some white-paper type documents can be found at the following URL: http://info.ComputingArchitects.com
Note that finished/polished versions are not available on that site due to
copyright/ownership consideration.
PROFESSIONAL BACKGROUND / EXPERIENCE:
Present - NYU
School of Continuing and Professional Studies (in-classroom and web studies).
At this juncture, I'm taking a moment to reinvest and broaden the scope of my
education and experience (part-time basis). This is in line with what I have
done the whole of my career.
Sept 2007 - Present
– Part time Consultant to NetApp (Network Appliance)
Part time Cloud Computing Consultant
I extend NetApp’s
basic enterprise monitoring platform (known as Operations Manager (OM) /
Distributed Fabric Manager (DFM)), by writing code to (1) tap into enterprise
events generated by this products and, where necessary, invoke customized
hands-off corrective action (such as just-in-time growing a volume that has
reached capacity) and (2) use DFM as a gateway/portal into the NetApp ONTAP enterprise, to generate custom dashboards (in
HTML or CSV format) to report the health of an entire NetApp
enterprise. I also perform heterogeneous migrations for their customers using
tools like SecureCopy, Beyond Compare, Rsync, etc. to NetApp filers
(Storage Controllers) from competitor storage platforms.
I work with clients to build Unix based Cloud hosted infrastructures to (1) host
previously in-house run applications on Cloud provider systems, (2) to setup
compute and storage Cloud entities to test applications on variously sized
platforms to assist in the right sized purchase of new equipment, (3) to setup
compute and storage Cloud entities to load test applications before they are
put into in-house production. The Cloud provider, for now, is Amazon Web
Services (AWS), which consists of their EC2, S3, SQS,
and SimpleDB (or MySql
if they prefer) products. Tasks may include creating a special DMZ/Bastion
security group to allow SSH from the public internet; creating special load
balancer AMI instances do distribute load among back-end servers; creating
isolated security groups that allow only specific traffic between that and
other security groups; ensuring data backup between High Availability Zones;
creating custom AMI’s; etc.

implement a web-based application that will be used by employees of New York
City’s 129+ agencies to enter in hours worked, vacation time, etc. The CityTime infrastructure will replace numerous older
mechanisms for entering and tracking such data, with a central modern system,
making the process more cost effective and forecast budgeting easier.
Technologies include, SunCluster 3.2; VCS 4.x; EMC Symmetrix; Clariion CX300; IBM
application server products (MQueue; WebSeal; WebSphere; TIM/TAM),
etc.
Sept 2005 – August 2006 INET (InetATS ECN)/NASDAQ,
Senior Systems Engineer
INET (formerly known as Island/InetATS and now part of NASDAQ), provides the transaction
network and engine (a.k.a. ECN) that implements what is universally known as
the NASDAQ stock exchange (the computing engine to which financial institutions
connect to trade equities/stocks). The core of this platform consists of a grid
of 1U systems running a 70mb custom Linux & JRE based O/S; and which work
together through a UDP broadcast-based protocol which glues them together. One
of these systems is the match engine (the single computer that interprets and
handles incoming requests), and the rest are systems that implement functions
and customer connectivity.
By necessity, the INET-based
platform is dynamic (say, to enhance internal back-end robustness; to expand
customer facing functionality; to comply with regulatory entities; to handle
ever increasing volume; to reduce latencies and increase response times etc.).
Therefore it is a system that is constantly researched and augmented by the
small team of engineers that work on it. My role on this team included:
· Instrumentation to measure/identify/improve
end-to-end UDP broadcast latencies throughout the platform (including use of
network taps, the sock/iperf/netperf/tcpdump/
ethereal utilities, etc.).
· Developed programs in C to: connect to a network interface (typically ethX but not necessarily) to watch-for/sense missed packets
in the sequenced UDP broadcast stream; to implement a client/server application
which provided out-of-band control of servers in the core ECN network.
· Designed and implemented a SAN using Qlogic SB5202 FC switches, and Nstor/Xyratex
4900 series fibre channel arrays. The SAN stores
(among other things) historical data concerning transactions that have occurred
on the core ECN.
· Undertook a project to design an environment
capable of creating tiny embedded forms of the Solaris and Linux O/S with
specific attributes such as: kernel versions; compile options; kernel
subsystems to include/exclude; versions of glibc to
compile against. Although the initial version of this environment would
produce kernel and ramdisk images that could be
embedded in the core grid of x86 based systems (via pxe
& dhcp), the design would also be extendible to
specialized hardware boards based on RISC/ARM and other processors. The idea
for the latter is to produce tiny java network engines capable of handling
closely spaced UDP packets, and to eliminate overhead associated with generic
stock x86 hardware (such as interrupts).
As part of this design, I had to
work on a platform that allowed hundreds of 1U servers (i.e. embedded x86
targets) to PXE/DHCP/TFTP boot tiny of custom appliance versions of Solaris or
Linux over the network. Anytime a machine was rebooted, its O/S would be
completely rebuilt from scratch, and is one reason the O/S’s was kept very tiny
(appliance like). From start (boot) to finish (running), it took about 70
seconds to build a machine. To do this, in Linux ttylinux
was used as a base, then stripping and adding files to that filesystem
as needed, along with the addition of a kernel and ramdisk,
created the final version; and for Solaris I used the x86.miniroot ramdisk filesystem and kernel,
which I opened up (via a lofiadm mounts) and
similarly customized it by stripping and adding what I needed. In both cases,
the design of the O/S was such that its application function (let’s say a UDP
packet re-request server) was not hard coded into it, but rather was designed
so that a boot script would, based on a configuration file it would FTP over (via
wget), dynamically customize the server’s personality
at boot-time. It was very scalable.
· Migrated
the InetATS DR site from
June 2004 – August 2005 Consultant
OpenSystems Engineer and
Technical Writer for various clients
· Storage Engineer -
retained in a consultant capacity to design and configure a Sun / Clariion / Brocade based SAN for Primus Financial.
· EMC Engineer (EMC residency program) - retained in a consultant
capacity to assist their customer, Rainbow Media (a division of Cablevision in
Jericho, N.Y.) to provision storage in a EMC Symmetrix
8430 and ED-1032 Connectrix based SAN environment.
· Technical authoring of Business Continuance processes, High
Availability best practice guides, and step-by-step HOW-TOs
for various clients of Sun Microsystems. A small sampling of the many documents
I have written over the years for clients, and for myself, can be viewed at the
following online address: http://info.ComputingArchitects.Com
Oct 2002 - June 2004 The New York Mercantile
Exchange (NYMEX),
Senior SAN Design/Architect/Implementation/Admin Engineer
(Consultant)
· Retained in a consultant
capacity by NYMEX to fully design and implement a multi-site SAN (Storage Area
Network). Other than my own, no vendor or third party professional services
were used in any of the work to be described. Please refer to the following
technical diagrams and papers, which relate to the work described below:
NYMEX
Clusters and DWDM distance SAN and Buffer Credit Calculations for Distance SANs
·
Successfully designed/specked out/purchased/installed/configured the following:
(1) Took two unused Hitachi HDS9960s, moved one to a
DR site, and got TrueCopy working between the two via
direct FC-AL over two DWDM lines. This step included upgrading HDS
microcode, provisioning disks via the SVP and Remote Console, creating an RCU,
ensuring different DWDM paths etc. (2) Based on the distance between the two
sites, calculated the BB & EE CREDIT requirements and procured and configured
4 McData ES3232 switches (a redundant pair for each
site); through a pair of local ISLs between the two
switches at the same site, and pairs of DWDM ISLs
between the two sites, converted FC traffic from just TrueCopy
traffic over DWDM to general FibreChannel SAN traffic
over DWDM (which included TrueCopy traffic) (3)
Purchased Hitachi SANtinel licenses for Lun Masking (4) as the first clients of the SAN, created a
mission critical VCS 3.5MP2 cluster (for a mission Critical Oracle Database) on
at one site, and synchronously TrueCopy replicated
the data to the DR site. Other accomplishments included creating specialized
High Availability storage solutions using multi-initiator configurations using
the D2 StorEdge array; configured Squid Proxy
servers; and other Sun/Solaris architectures/implementations.
Jan 2001 - Sep 2002 Cablevision Inc.,
Hicksville,
Lead Senior Sun/EMC/Veritas/Solaris Infrastructure Design
Engineer (Consultant)
·
Retained in a consultant capacity by Cablevision core Engineering to design and
implement all aspects of the compute and storage processing infrastructure
(Sun, EMC, Veritas, etc.) that represents the backbone of what will serve a
projected 4 million households with a new home media service known as the iO.tv (i.e. Interactive Optimum, which is based on a
digital set top box that uses http to display a scalable and remotely updatable
user interface, and a cable modem to send encrypted digital video on demand,
email, and other plug-in interactive services). Among other things, I designed
and implemented (without EMC professional services) the EMC based SAN that
services all the functions in the Master Head End datacenter (customer
database, the digital movie encoders, the Conditional access smart card
encryption system, set top box auto provisioning system etc). Technologies
include ED1032 Connectix; 8730/8430 Symmetrixes; Fibre Zone; Volume Logix; ECC 4.3; SRDF; TimeFinder;
Persistent Binding; PowerPath.
· Designed and built highly
available HA clusters based on Veritas VCS and various other availability
technologies and best practices (PowerPath/JNI/Qlogic,
DMP, IP multipathing, mirroring, load balancing
through Resonate etc);
· Designed and coded a black
box engine that sits on top of Sun's jumpstart product that eliminates all of
the traditional shortcomings of jumpstart and makes it enterprise scalable. I
evaluated and installed the new SunFire 6800, 4800,
3800 products; the evaluation included creating single and dual partitions and
the domains within them using the System Controller Console and Domain Console
CLI; physically adding and removing components like CPU/Memory, Interface
Boards, PCI cards in one domain to verify the isolation in other domains; flash
upgraded the 6800 & 3800 firmware; extensive load testing including designing
and creating a platform for Oracle 8.1.7/9i Parallel Server testing on EMC
storage. Essentially, I designed and physically implemented (always with an
enterprise and scalable mentality) anything to do with the back end (Head End)
computing infrastructures; it will ultimately service up to several million
households in the New York Tri-State area.
Aug 1999 - Dec 2000 Mail.COM Inc.,
Lead Senior Sun/EMC/Veritas/Solaris Infrastructure Design Engineer
·
Engineered, built and administered the EMC-based Storage Area Network (SAN) on
which Mail.COM hosted its critical businesses: consumer, partner ISP, and
business-to-business messaging (for example: Mail.com, Email.com, Iwon.com,
CNN.com etc.). The design consisted of four EMC Symmetrix
3930s, two 3830s, three EMC dual director Connectrix Fibre Channel Switches, four EMC Celerra
File Servers, and a dozen 28CPU Sun UEx500 Enterprise Servers. Additional
components include software components such as EMC PowerPath,
ECFM Connectrix Manager, Volume Logix,
ECC SymCLI & OSM Manager, Veritas Volume Manager
(VxVM), Veritas FileSystem
(VxFS), etc.
· On the SAN side of the
design, considerations such as redundancy and resiliency were made possible
through multiple active (Power) Paths across different Fibre
Channel switches, JNI HBA boards across different Sun I/O boards, VxFS for quick filesystem
recovery, and VxVM mirrored O/S and SWAP volumes.
High availability considerations were accomplished through the configuration of
an additional UE6500 with visibility to the entire SAN storage pool via Fibre Channel zoning and Volume Logix
HBA to FA hypervolume authentication. In this
configuration, the UE6500 can assume the compute task of any of the other
·
On the NAS side of the configuration, multiple NFS volumes are hosted by
multiple EMC Celerra File Servers. Performance and
availability design consideration were accomplished through the combination of
2 to 1 active/passive data mover failover configurations, redundant 100Mbit ethernet links across different datamover
NIC cards and Cisco switches, etc.
·
Based on Sun’s Jumpstart model, engineered a method for jumpstarting machines
on Mail.COM’s global networks, without the need to
configure jumpstart or even boot servers on remote segments. Traditional
jumpstart environments minimally require a boot server on each client network
segment. A result of this Light Weight Jumpstart Server design is that network
segments no longer require (and in fact are prohibited from having) their own
boot, configuration, and install servers. The configuration, install and boot
server for all of global Mail.COM exists, and is maintained, in one location (
Oct 1998 - Aug 1999 Chase Manhattan Bank
H.Q.,
Global Systems Solaris/Unix Design Engineer (Consultant)
·
As a member of a three person Engineering team, I designed Sun Solaris-based
solutions for Chase’s global business groups. Projects include the design, test
and building of a Veritas FirstWatch based HA
disaster recovery platform for the Chase private key infrastructure (PKI) using
multiple Sun machines connected to D1000s in multi-initiator fashion; SVR4
Packaging of products to be put into Chase's engineering build of Solaris.
Apr 1995 - Oct 1998 SUN MICROSYSTEMS
INC.,
UNIX/Sun Integration & Support Engineer for Sun PS
·
As a senior member in the professional services division, provide technical,
integration and consulting services for business clients that use SUN Solaris/Sparc-based computer and storage networks as their
enterprise-wide client/server platform. The vast number of hardware &
software products and customer UNIX configurations required of me a rapid
learning curve, dedication and passion for what I did. As a result, I was
awarded Sun Microsystems Northeast Area's Engineer of the Year award, and
became a Senior Systems Support & Professional Services Engineer within my
first year at the company. Here are a few of Sun Microsystem
client assignments I architected and implemented (hands on):
· For Alliance Capital
Management Corp, I built an environment consisting of UEx00 enterprise servers
with RSM-219s and EMC storage for a y2k testing lab. Technologies included
Symmetrix 3830, PowerPath,
Veritas Volume Manager, etc. Wrote a C program that allows
any user on a system to have independent control and view of the date &
time without altering the UNIX system (kernel) date & time. This
ability to change the date/time anywhere in the range "01/01/1970
00:00:00: - 01/19/2038 03:14:07" at the user shell level meant that
multiple developers could test for Year 2000 compliance, each with a view of
their own time (within their UNIX shell), without disturbing the REAL master
system time.
· For Olsten Staffing Corporate
HQ, as the SINGLE systems architect and integrator, I deployed a Sun/EMC
Enterprise-based infrastructure for year 2000 efforts. The hardware I
configured are: ten E6000s, one E5000, one E4000,
three RSM2000s, two Ultra2s, Sun to EMC connectivity (2.9 TeraBytes
over two Symmetrix Storage Units: 3700 and 5700
models). With this equipment I have built from the ground up the following
configurations:
· Four E6000 HA Clusters
(pairs) using Vertias FirstWatch
HA and shared EMC storage over Ultra Wide Differential SCSI interfaces;
configured carefully designed striped volumes using Veritas Volume manager and
Veritas Filesystems to work optimally with Oracle
7.3.3 and 8; wrote supplement programs to the Veritas Oracle Agent API to
start/stop the TNS listener during failover and to start/stop the HA monitoring
of Oracle for DBA use when performing database maintenance. Configured dual ATM
interfaces to support LECS and LanEmulation protocol
for IP support over the ATM fabric. Configured an RSM2000 and associated LUNS
on a E6000 on one of the HA pairs for private disk
storage. This cluster doubles as a Load Test Generator (Load Runner) / Oracle
Test Database pair. The extra RSM200 added the complexity of managing different
disk controller and minor device numbers between the two machines when using
Veritas Quick I/O for databases.
· Two E6000 machines using
Solstice DiskSuite and shared EMC storage over Ultra
Wide Differential SCSI interfaces; stripped volumes were carefully configured
to work optimally with Oracle 7.3.3 and 8; dual ATM similarly configured.
· An E6000/RSM2000 and
E4000/RSM2000. Created both RAID5 and RAID 0+1 striped LUNS
for use with Oracle and for Print spooling.
·
Configured redundant Ultra2 pairs to serve corporate-wide DNS name services,
home directories and standard application repositories (for automount),
rdist distribution services to the
· Installed Oracle 7.3.3 and
created a basic database. With input from DBAs,
created optimal database environments: in /etc/system, tune MINFREE and
LOTSFREE kernel variables, exclude unnecessary modules from being loaded, set
SCSI options for optimal disk I/O, create UFS and VXFS filesystems
with appropriate block sizes.
· Install, debug, configure
and/or design the following UNIX based subsystems: installed and configured
Solaris O/S, 10/100 BaseT & ATM Classical IP and LanEmulation based TCP/IP networks, RAID Volumes on Storage
Array Disks using DiskSuite or Veritas, in memory tmpfs based filesystems, NIS and
NFS services, Scripted backup schemes, User Accounts, Automatic Installation
via JumpStart, Network Terminal Servers, Configured
departmental intranets with HTTP and FTP services, Basic firewall with
FireWall-1, High Availability Servers for NFS and Oracle Database & TNS
Listener processes.
· For Mayer & Schweitzers Inc., I created the custom JumpStart
server used to build their 100 position UltraSparc
based trading desks.

·
Designed and built the DSP hardware board that predicts the signal vectors
(i.e. pixels position, velocity and hue) for DirectTV
broadcast signals. The output vectors are used to substitute for momentary
signal loss during atmospheric disturbances.
· Wrote FirmWare
in C to interface a UNIX serial port to a receiver board used in RCA's DirectTV development project. The interface provided the
means by which to transfer test vector information to and from the embedded
system under test.
· Developed C programs to
predict the behavior of hardware being developed for a new broadcast system
(DirecTV) designed to transmit several programs over a single satellite channel
using MPEG compression techniques.
